Making Cast Iron Bronze - Ingot Give Away
HTML-код
- Опубликовано: 16 окт 2024
- I am making cast iron bronze again with a slightly different method, some crude tests and an ingot give away.
Following on from last weeks video I make cast iron bronze again using cast iron, copper and aluminium but with a slightly different method.
This week I show how I make this cast iron alloy, a aluminium bronze with cast iron and cast it into some 1kg ingots. As I recently reached 1000 subscribers I have 3 of these polished bronze ingots to give away.
The give away video will be later this week.
This is an extremely hard bronze and is well suited to swords, axes, knives, hammers and other similar tools. It should also hold an edge well.
This cast iron bronze has a beautiful golden bronze colour.
The recipe for this weeks cast iron bronze alloy is:
70% Copper
20% Cast Iron
10% Aluminium
Expect losses of 30% to dross as it currently stands.
To make this bronze, melt the copper and the cast iron together, add the aluminium when the copper has melted and mix well, keep heating until everything's melted, skim and pour. Temperatures need to be kept in the 1150C - 1300C range and must be mixed extremely well.
This cast iron copper alloy recipe was provided by Daniele Bosco. You can see his RUclips Channel here / channel
Daniele is from Italy and has studied metallurgy for 5 years.
He has several other recipes for this cast iron bronze which I hope to try out in the future.
Hope you all like this video, happy casting.
Andy
Tried this one again, still a few issues, but got some lovely ingots to give away. Might not be easy to cast with, but if you like your ingots and don't mind losing a bit to dross this is a great metal. Cheers all, hope you enjoy the video. Best wishes Andy 🥂🥂🥂
MeltandCast Strange I thought the flashes I saw in the last video were small” thermite reactions from iron oxide mixing with the molten aluminum. I didn’t think about trace magnesium causing that reaction.
Have you tried acid etching a slice to examine under magnification?
That takes a beautiful polish...how long does it stay like that?...
Due to the narrow temperature range of pouring, perhaps centrifugal casting is the ticket to successful end results on a project. What do you think?
@@stanervin6108 No mate not tried that... not sure if I will... I'll probably try this recipe a couple more times and then move on to other things... Cheers Andy 🍺🍺🍺
I think this was marvelous experiment.....so mixture is 70% copper....20%cast iron....10% aluminum...and 2.5% tip of stir rod?.😁....it was a great melt.
Haha, that chemical reaction definitely took place and made some hellish heat for sure.
Subscribed, glad RUclips recommended this as I love these types of videos. Great pour and interesting look into alloys. Looking forward to future videos
Thanks for the sub Edward, glad you enjoyed it mate. Cheers Andy 😎😎😎
I hope we see more of this new alloy and are able to find a suitable recipe for casting in molds!
Would love to see a snap test to check grain properties. Would be interesting if it created small hard crystals like cast Iron or Bronze, or if the copper gives it a little flexibility.
And a proper HRC test
Perhaps send it to Cody's lab hes a geologist could do some neat stuff with it
I second this - he'd have some great fun with it, from analyzing it with his spectrometer to probably making a nosecone for a mars probe. ;)
I can’t wait to retire so I can do cool stuff like this
you would need a metallurgist, or need to send stones ;P
@@Alrion1704 Cody is sort of a "mad genius of all trades". He mines, grows plants, does experiments on precious metal recovery / carbon capture / charcoal generation, recovers range lead, etc etc etc. He's currently in the middle of nowhere in NV building 'chicken hole base' which is meant to emulate a mars mission.
Since the losses are almost entirely Fe and Al, and those are by far the cheapest and most abundant of the three metals in the melt, this seems worth the loss to me!
I don't think I've ever had my forge up past 2400, kind of scared to go that high...but that is a gorgeous bronze. Some day! Great video
its awesome to see you adopt new ideas like testing them after or working on them more
Now that is beautiful - love the crystalline structure on the outside, but when you cut it - wow - it looks mint! Well done!
My fiance and I are going to be keeping an eye on your progress and, hopefully, trying out this alloy in our smithy. Looks FANTASTIC!
And hello from Ohio, US!! :D
Thanks Eden, and greetings from not so sunny Cambridge !!! It's not so easy to make, but it's worth a go. Lots of people would like to know how it might forge. Daniele says it can be hot forged. Do let me know how you get on, I'd be really interested to see the results. Cheers Andy 🍺🍺🍺
I really like the one with the two beads, it has a certain charm to it. Love the cast iron bronze idea
my metallurgy training and study's can back to me with power when i saw your first vid on this
aluminum always has a thin oxide layer on it and iron oxide and aluminum oxide make thermite, and with the magnesium impurity you where making thermite in your melt.
but the copper is mixing and interfering with the aluminum and iron with atmospheric o2 thermite reaction.
your still losing a lot of aluminum as a gas in your melt, but the same happens when you make brass with the zink
so id say this is more in the famaly of brass for the melt but bronze for finished product
but it is at the end mostly copper with iron or as you say "Cast Iron Bronze"
id love to see a cut and acid etching of one of the ingots as well as how it melts a second time as brass will out-gas zink with each melt and some other alloys will make non alloyed pockets in the castings with each melt
also my metallurgy science demands to know its physical property's like pull tear and compress strength, its corrosion resistance, its hardness (it make a great bell) is ductility or brittleness, is it still ferrous? (will a magnet stick to it?) whats its electrical property's? whats its magnetic flux property's? i have so meany questions.
Lovely looking result and thanks for showing that experimentation can be hard work. Hope you've inspired enough people to contribute refining the process and show some finished works.
Thanks Tim, glad you enjoyed it mate 🥂🥂🥂
Interesting exercise! I used to be the electrician in a foundry that specialized in stainless and hastaloy casting for pump housings and propellers. The temperatures involved are pretty awe inspiring!
Cheers Gary, I just Googled Hastelloy, seems like a very complex metal judging from the ingredients. I bet you need some serious heat to combine that lot. Cheers Andy 🍺
I think the trick to making this alloy may be to leave it in the heat for longer with occasional stirring and a higher heat if possible. Why I say this is because it seemed to be a little bit clumpy on the first pour which I think is a sign of a non-homogeneous melt. But I'm just a guy that watches too many videos like this and the only school I have similar to this is my immersion in chemistry of which I haven't completed yet :/.
The last ingot did look a lot better than the others didn't it ? 🤔🤔🤔
I would be most interested in the electrical properties of this of this alloy. In RF and electrical systems we use Beryllium Copper extensively. A new lower cost alloy would be a great thing. If the resistance is low enough it could improve the safety of structural wire. The applications are nearly limitless, if it has good electrical properties.
I had a thought that if the alloy maintains some of the magnetic properties of the iron you may have something very special for building coreless transformers. Improving the efficiency of transformers has nearly limitless applications and benefits. Everything from power grid sized transformers to microelectronics would benefit.
iron has a higher resistance than copper by a factor of ~5.
This could make an absolutely beautiful damascus!
Excellent job, every pour is a learning experience. Enjoyed the video, keep up the great work.
Thanks James 😎😎😎
I have a character in my books who uses a bronze sword. This would be the absolute idea material for it! Brilliant! Thanks for all your effort in bringing this creation to life!
Thanks Mitch 😎😎😎
Really fascinated by this compound! I am a blacksmith and am wondering if this could now be hammer forged into items or if it should only be cast into shape... What do you think??? Looking forward to the giveaway! I'd love to experiment with it in my shop!
I have a blacksmith friend, if I do make this again I'll give him a piece to forge. I'm fairly sure Daniele said this can be hot forged, not 100% sure, but I think so... Cheers Andy 🍺🍺🍺
Awesome job man !!!!! Unique for sure !!!! Love it !!!! Dang that is strong!
Thanks David, enjoy the weekend buddy... Andy 🥂🥂🥂
Really interesting thx to showing, looks amazing how you do it.
Just found your channel. Awesome. Love it. Keep up the good work
Cheers Eric, glad you like it mate 🥂🥂🥂
20:47 actually that was testing strength and ductility. The point of failure would've indicated its strength while the mode of failure (shattering vs deforming) would've indicated ductility. Hardness requires special tools or sets of standard files.
I have seen your first video on this alloy, and immediately had the idea of making a watchcase out of it. Back then I was wondering how I could get my hands on a small piece of that alloy. Really looking forward to the giveaway.
Kurt
PS: defenetly got a new subscriber!
Thanks for the sub Kurt.. Cheers Andy 👍👍👍
OMG those are gorgeous!!!
I love the strength of the metal!!
If I win one of those I'm going to forge it into something, blacksmith style!!!
Just tell me what I gotta do!!
Also, thank you for wearing your respirator this time, and yeah this aluminum was way better quality.
Anywho, amazing melt as always!!
Cheers, Kayla.
Thanks Kayla... Give away video will be out in a few days... Have a great weekend... Andy 🥂🥂🥂
Fascinating. Will you be testing the tensile strength any time soon? I am more than interested to see how it compares to iron and steel. Thanks.
That looks like a tough beautiful ingot you've made there...I'm just beginning to do my research and make a forge...that little ingot would make a nice set of bolsters and pommels, great video and very brave of you to jump right in there like that.
Thanks Daniel, glad you enjoyed it mate... Andy 🍺🍺🍺
Awesome. Looks extremely tough. Love to see a knife or axe made from this stuff to see how it performs. Thanks for all the great info. Awesome video.
Cleans up really nice for a 2nd 1st time pour. Looks to be a very interesting material, think i need to dive into some books to understand the aluminium's reaction in the cook, and the effect it has on the final structure. Thanks for being that chap who likes to try new stuff.. Joy to watch, very avant-garde! Be very interested to see what can be done with it, cast or Forge worked, new stuff is grand lol
Thanks QziQza, I really appreciate that mate, very kind of you. Best wishes Andy 🥂🥂🥂
The luster on the metal is amazing, beautiful!
Thanks Jose, I appreciate that mate 🥂🥂🥂
Those are just spectacular, mate! Great video and very well done with the subscribers.
Thanks Chris, How are you mate ??? Hope things are all good your way ??? Cheers Andy 🍺🍺🍺
I would be interested in seeing how this material forges. I wonder about edge retention, abrasion resistance, and to what extent it will work harden.
I watched your last video on this stuff, and I just subscribed. I haven't had a chance to look at your other videos yet, but I am interested to see what's in the back catalogue.
Daniele says it can be hot forged and quench hardened. If you can find his thread in the comments you can put the question to him. Other than that until I try it, I don't know mate, sorry !! Cheers Andy 😎👍🥂
I would love to see you make up an ingot and do a collaboration with a blacksmith RUclipsr to see how well they can forge it out and how well it can hold up to abuse
Alec steele
I second Alec Steele. great guy with an amazing blacksmith channel.
Agreed on sending a sample to Alec Steel
What a fantastic idea! I never would have thought of that alloy. I would love to cast something with that alloy.
I'm so stoked about this new metal! Hoping to get a couple of the boys to make this in the summer
that is gorgeous! I would love to know later on how well it resists oxidation.
Amazing experiment. I'll be excited to see what kind of quality it lends to a tool or blade.
I have no idea why but just watching this process is .. relaxing? I love this for some reason. Also explaining why you are metaling / adding metals in a certain order (to create a chemical reaction to create heat at the right time to melt the cast iron) also very nice. Thanks.
Thanks Walter, glad you enjoyed it mate. Cheers Andy 🍺🍺🍺
Awesome and unique for sure Andy. Don't be afraid to to use extruded aluminium. Extrusion is just a formation process just like casting. It can be many different grades. The only way to be sure is if it is marked by the manufacturer. I can't even scratch the surface by leaving a comment. I did send you an email on the subject
Thanks Relyonno, just found your email... Cheers Andy 😎😎😎
Interesting that your "skinny bar" had much tighter grain structure and a smoother overall finish. That was the bar that you had to reheat to be able to pour it. I can't help but wonder if you need to heat for a longer period of time to let it do it's magic........
Quite possibly... I also noticed that... definitely worth a try... Cheers Andy 🤔🤔🤔
Or you can melt, let it cool to cherry red and then reheat and melt again for pouring.
Maybe do so a total of two or three times and see what happens.
Scary part there is he got dross with both melts. If that much dross forms each reheat, he could be looking at 50% or more material loss.
@@angelaabrams9108 The dross that came out on the remelt could be the result of oxidation caused by an oxygen rich atmosphere. As a test, I wonder what would happen if on the remelts, the crucible were flooded with argon to block oxygen out of the mix. Doing that would require using an induction furnace for heating tho..... But then we'd be getting into exotic metallurgy....not the realm of a hobbyist ....LOL!
I wonder if this recipe needs to have glass covering it at the top like Wootz steel is made. The glass melts first, and covers the metal so that oxygen can't interact with the metal while it's bonding. Might be worth a test or 3...
A bit of loss for a great alloy, worth it! Machined or forged would be interesting. Corrosion resistant?
Wear resistance? All things to test.
Looks like it will be hard to cast with.
Thanks for sharing.
Thanks Das 🍺🍺🍺
This gets more interesting with each pour, I'm impressed with the hardness/ductility test. Subscribed to see where this goes.
I keep thinking about the sword of Goujian with that gorgeous golden colour and hold out hopes you and Daniele have discovered something genuinely new and useful.
I really hope you figure out how to homogenise the pot and limit the oxidation going on. I wonder if any other traditional bronze ingredients will alter the alloy predictably. like a pinch of tin to increase hardness or lead for softness. I haven't a clue what bronze uses a flux, but it looks like the lumpy pour could do with some? Would adding carbon somehow give a steel bronze, instead of iron bronze? Keep me well away from boiling metal and dry ice, lol.
If I had a setup like yours, I'd be ordering all sorts of elements online and chucking it in to see how it affects the stew. One would think all this has been figured out by now, but the comment section has me wondering.........
Incredible material and great vids man. Just recently found your channel and will be sticking around. Id love to work with some of these materials, keep up the good work! Subscribed!
Thanks for the sub Canon... Keep an eye out for the give away video.... you never know hehe. Enjoy the weekend mate... Andy 🥂🥂🥂
Thank you for sharing your time and effort. It is a pleasure to watch.
Cheers David 🍺🍺🍺
I just discovered your channel . You have added to my entertainment. I will have to look back and see what you have accomplished. I am always trying to cast metals. I would loce tomake a cast iron straitedge. Thanks !
Mike
Glad you like my bumblings in the shed mate, hopefully I can get a bit better at it in time... hehe.... Cheers
Nicely done, I really loved the feathery pattern after the original pour, I suspect it was from the viscosity of the alloy. Then you cleaned them up and it looks just like bronze to me, I wonder how much heavier it is too just out of curiosity.
Great job, glad this batch didn't flash like the last one.
All pretty cool to watch. One of those ingots would be a very nice conversation starter
Cheers Ted, to enter the draw just comment on the most recent video "Subscriber give away 2020". All the best... Andy 🥂
It'd be interesting to see what the hardness is
Ave did a video where he tested rockwell hardness by bouncing a ball bearing down a straw and seeing far it bounced as a cheap way of doing it
Even cheaper is to just buy the hardness testing files... I'd start there.
@@Mmouse_ OK, so why don't you buy them and mail them.
I checked for an alloy similar to yours and could find anything like it for sale. So, yes, everything I see says it's either brand new or lost in ancient times.
I'm so fascinated by this, surely sticking around for more. We really need some way to know if all that iron alloyed in the end result. This could be just a refined form of aluminium bronze, like everybody is saying. But it sure does look promising.
F st and Luckygen made some interesting comments... Carbon, graphite and copper just don't behave too well with each other... without going in to too much detail, they are an incompatible pairing which is why there's so much waste and prone to spots. It might never work "well", sure you can make it... but you could perhaps make something better, with less work and much more reliability... Still Daniele's recipe is out there if anyone fancies it.... Cheers Andy 👍👍👍
This is awesome!!!! Watching with much anticipation........
I am absolutely loving how beautiful they look all polished up. It'd make one hell of a beautiful knife or even better...... An ax!!
Thanks Wiggle, Daniele made a sword with it, possibly even an axe... he's managed to cast it successfully... even If I don't think its easily cast. The ingots sure looked good though. Maybe they could be made into something by a smith... Cheers Andy 🍺🍺🍺
@@MeltandCast thanks for sharing your videos and thank you for replying! I'll be going through your backlog soon. I've already seen a number of them I've gotta watch. I don't have any personal experience with casting, but it's something I've always wanted to try at least once. Does Daniel have any photos of his sword or possible axe posted anywhere?
Some of my older videos are a bit sketchy mate, kinda learning all this stuff as I go.... hehe. I'll ask Daniele to post something up showing his sword and axe... Cheers Andy 🍺🍺🍺
Looks like some nice grain refined aluminum bronze. Tough stuff for sure.
Iron is a perfectly normal additive in aluminum bronze, which this is. Materials like this with tighter alloy tolerances than this can achieve strength as good as steel.
Cast iron has the highest melting point of the metals used here. When the alloy hits a cold mold the cast iron solidifies first forming an iron concentration.
Lovely looking alloy does it behave any better on the second melt .
Amazing product! It would be great to have the possibility to try it! I'm a knifemaker and it would be very interesting to test it's propriety. I think it would be a perfect metal for guards
I’d love to see this go to a blacksmith to see if he could make a knife.
Knifes are a good test of a materials properties.
I certainly would like to try it out, that's for sure!
Liam Armstrong i had the same thought as i was watching this video. It would make a handsome yellow knife too.
Yes, a forge test would be great! How does this alloy take a heat, Does it forge weld? Does it deform without cracking? Can it be tempered? Do send a piece to a blacksmith to do these tests.
@@tree_relics I'd gladly do some tests with it! I only just today got my gas forge set up, so now I have access to both coal and gas. Given that it is a copper-based alloy, I would make a guess that it does not really forgeweld as steel does, and that it might be red-short, but it should work-harden, but I haven't an idea what aluminium and iron+the bit of carbon does in what is essentially a bronze, we touched metallurgy only very briefly in blacksmith school. :)
Very good idea. Im wondering how bendable, how well it takes/keeps and edge,... The works!!
Very nice looking ingots. Very interesting combination of metals. Nice work!
Thanks Pharaoh 👍👍👍
Very interested in copying an doing an axe as well as seeing how alloy works in heat transfer via being a skillet.
This would be fun to try and make a few things out of. Maybe a straight razor/knife or bottle openers and whatnot.
I’d love to see how it machines! Also that material would probably make a great non sparking/marring hammer.
Also would love to see if it corrodes in the weather!
Well, I must admit my surprise that they stood up to the test so well. How magnetic is the slag? Could most of the iron be getting rejected into slag? That would leave you with essentially aluminium bronze which would behave like your test piece. Great video again. Thanks for making it. Mike
Good point Mike, I didn't think to test that, I'll do that next time I'm in the shed. I'll report back on the next video. I'm also starting to think i'm just making aluminium bronze albeit in a much more convoluted way... Commercially produced aluminium bronze does have iron in it, whereas most RUclips aluminium bronze is just copper and aluminium... Of course it could be I'm just extremely bad at making alloys... Daniele's managed to make this with few losses - and been able to sand cast it too... Cheers Andy 🍺🍺🍺
@@MeltandCast The alloy you are making is likely just C954 aluminum bronze, that much iron simply isn't going to dissolve in copper. It will separate out as a copper containing iron alloy. That will also mop up all the carbon that was in the original cast iron (which is insoluble in a copper alloy), which will probably form a bunch of cementite, which would explain the thick, slushy crud in your crucible.
That's pretty much what Luckygen and F st said, that the carbon and resulting graphite were incompatible... I'll make this one more time as Daniele has a suggestion, but I think the result will be similar. I have a lot of other projects I want to work on, so I won't be pursuing this too much afterwards, apart from perhaps making some ingots to send to other channels to run some tests. Forging, stress, shear, strength tests etc. From the comments a lot of people would like to see some numbers, so I'll try and make that happen. Cheers Andy 🍺🍺🍺
Can you forget it? You should send one to demolition ranch, Alex steel, bigstackD, all pretty good you tubers and see how they hold up to a few test.
I was just thinking that. If Alec Steele learns of it, he might just make some himself and then we'll see a 100 part series of him trying to make a sword or something of that nature. I'd like to see that.
Or How to Make Everything.
"Today we're going to invent an alternative bronze, called Iron Bronze, or Daniel's Metal. Now, since we haven't invented Recipes or Printing yet, I'll be eyeballing this"
I'd love to see Alec Steele try his hand on this, alternative is to grind up into smaller chunks and re-melt it, and try re-casting it, or both!
Send one to clickspring as well. Maybe he’ll find a use for it
I guarantee this will
Shatter into a thousand pieces if hit by a bullet
That was a stress test. Very impressive. I am very tempted to give this a go. I am planning on trying to melt some bronze from some old valves, see how they turn out. I'll add it to my Que lol. Nice work Andy.
Please do Wulf, I'm sure Daniele would love to see his metal being experimented with. You'll probably get some losses but the ingots do look great. Cheers Andy 😎😎😎
Glad I found your channel. Glad I'm not alone in playing with alloys.
Wow that is hard. Not as hard as the steel spike but definitely not soft. Awesome alloy. 👍
Thanks Kyle 😎😎😎
That stuff is super cool. It would make for interesting medium to make stuff from
I've never done a pour but would love doing one. I think yours went well. Good job
Gorgeous! I wonder if someone could make some nice Damascus blades out of it and whether it would weld to steel
Awsome alloy👍 can't wait to see how it casts
Badly at the moment I suspect haha... Cheers Andy 🍺🍺🍺
Might make nice sword fittings. Although besides a Bronze style sword I don't think it's going to out perform good steel.
I bet that stuff would make some awesome reeds for harmonicas.
Or maybe even violin strings!
...a silk core, wrapped with this, then ground smooth. Installed on a Guarneri pattern violin... you would get some incredible velvet warm tones.
Shame about the loss but it's a fascinating process. Do you have any thoughts about what might happen if one were to try to make an alloy like Field's metal using zinc in place of Indium?
I'm not sure mate, I don't have much understanding of metallurgy... But fields metal is a clever invention. I like the way it can be used to fill parts to enable CNC machines to create very thin walled components and for drilling hollow tubes without leaving a burr on the inside... smart... 😎😎😎
Just found your videos today. And promptly subscribed. I'd love to try and machine that stuff. Or better yet turn some on the lathe.
Thanks for the sub Eleventeen, much appreciated mate. Try the give away in a few days.... you never know hehe... Andy
@@MeltandCast no problemo
I'll be sure to try for the giveaway.
This metal seems to show promise :-)
Making a sword with this should result in a beautiful blade indeed.
I've not long got into melting too and would love to add one of these to the collection 😉
Thanks Kev, try the giveaway video in a few days mate... It will be obvious from the title. Cheers Andy 🍺🍺🍺
@@MeltandCast will do dude 😁
Love your process. simple but effective.
Just had a thought pop into me head, what about adding some cobalt as it can alloy with either steel or copper and thus help meld the two together? I would say about 5% cobalt. Sure would harden it up a lot more too.
if you used a high frequency induction heater furnace, could the magnetically caused convection movements help with the mixing? Great videos btw!!
Thanks Sivanesan, I'm not sure, I don't know much about induction furnaces... Cheers Andy 🍺🍺🍺
I wound up making a bit of "bronze" that was purple. I was just Linda playing with stuff. Mostly started with some red brass, added tin, aluminum. Not sure on ratios, etc. Havent been able to recreate it sadly. I thi k I may have also added in some iron and zinc. And maybe nickel. Basically i just kept throwing stuff in.
Haha... nice... although mixing metals can be dangerous... be careful... Andy😎😎😎
pix plz ;)
Beautiful color! Well done sir.
Thank you 😎😎😎
Interesting video again! Wow I thought I had mistaken myself, but I saw it right! congrats with passing 1k subs, already heading to 2k! How did you do that? You scared me a bit by stepping over that red hot full crucible just before the first melt. Nice ingots :)
Have you tested the hardness ? It would be great, to see how it play's out when it's machined !! Do you think the dross is mostly comprised of iron ? Great Work !!!
Thank you Joe... I would guess the dross is mostly iron and aluminium oxide. No testing has been done so far. Someone else will have to make it to run some tests. I just wanted to have ago at making Danieles recipe for this alloy. I'm back on the casting now, I may make it again in the future but probably not for a while. Cheers Andy 😎👍
It is an interesting mix. With last weeks video, I was thinking the temperature was so hi to melt the cast iron that it caused the aluminum to burn or something and most of it was the dross.
Such a beautiful color when you cut it in half. It will be interesting to work with.
Thanks James, it was the magnesium content in the aluminium last week... It's not supposed to flare like that. Cheers Andy 🍺🍺🍺
It's certainly an interesting alloy, has a wonderful gold sheen to it. I think it might be something that has a very short window for casting though, it looks like it looses heat incredibly quickly with how quick it thickened up. Your first attempt though, I'd like to see a remelt and mix on it, see if it will blend a little better, a comparison between your accidental alloy and the actual alloy would be interesting, see if that magnesium makes it tougher or weaker. Either way it was certainly a light show.
Might be a good heat sink material, then. If the conductivity stays close to as high as copper, this may be a fantastic wiring option!
God seeing that golden shiny ingot makes me want to melt some metal, but i need the snow to stop falling and melt away. The ingots are beautiful and it makes me want to give this alloy a shot. It's awesome!
Thanks Riley, please give it a got, Daniele would be really pleased to see others try. Just factor in the losses, unless we work out how to fix it... Thanks Andy 🍺🍺🍺
What is the difference between a heterogeneous mixture of metals and an alloy, if any? Chemical bonds, I'm assuming.
But I find it hard to believe this hasn't been discovered before. What happens when it is reheated to temperatures that would normally melt aluminum bronze? Can it even be forged? What are the properties when annealed or tempered?
I am very curious and fascinated by this. It looks beautiful.
Thanks Memespace, I've no idea mate, I'm just a dude in his shed playing with molten metal.... I have no training in metallurgy. The recipe for this was given to me by another subscriber. I'm just trying to re-create it. Cheers Andy 🍺🍺🍺
could you please try and etch it after a quick polish ? like the one you cut down the middle... would really like one of those for my knifemaking...
When railroad rails are welded, they use thermite to melt the powdered steel and powdered aluminum together. The aluminum works to heat and clean the welding steel. Same gig you got going.
I'd like to see what Clickspring could do with a chunk of that alloy
If it's really as hard as steel, he'd be stuck with his files I think. His lathe and cnc machine are pretty small, and he always seems to work with softer metals. I love his stuff, but he might not be the right choice
@@gamemeister27 Maybe, maybe not. Hard materials usually take a fine polish although they are more difficult to work as you point out. If there is anything exceptionally shiny, it's Clickspring's work
Clickspring's work is amazing, I saw his card press video a while back.... stunning work. Thanks for the reminder popped him a sub !! Andy 👍👍👍
You should try bringing one of those half-pieces to a fine polish, high-grit sandpaper with some oil (the flatter surface the better; I normally tape mine to a sheet of glass) should do the trick. I'd love to see what the crystal structure of that alloy looks like.
Nice tip with the glass, I'll do it if I get the time... Cheers Andy 🍺🍺🍺
Soft enough for vise Jaws to mark it up.
Vice jaws will mark high carbon steel. Marks dont mean a metal is soft.
Perhaps it can be heat treated.
@@barongerhardt My pondering was just an abbreviated form of me wondering if this alloy can be hardened and tempered by heat treatment.
IOW, is this a heat treatable alloy?
If so, it would open a lot of possibilities for it.
@@barongerhardt That's what I was thinking, since it's a copper alloy. But, I've been wrong before.
@@fortj3 since it has some cast iron in it (cast iron contains carbon), it could maybe be quenchable?
What about the two little buttons that came off of the bar you cut? I'd take one of those off your hands for ya!
Now this is unique. I'm really curious how these would forge and be shaped. I can see some pretty, pretty axes, hammers or even knives in my mind being made out of these.
Daniele says it can be hot forged and has cast a sword and knives with it. I couldn't make it work for me though... Cheers Andy 🍺🍺🍺
@@MeltandCast Cheers! If I was given the chance, I'd take it to the forge and anvil and see what I can do, worst comes to worst, I've got a gas forge now and could probably re-melt it, if it shatters during forging. It'd be interesting to go side-by-side, use cold-hammering and annealing for one half and forging it hot on the other and see how they differ.
Beautiful result again.thanks Andy.🍺🍺
Thanks Martin, glad you liked it mate. Cheers Andy 🍺🍺🍺
There's a new way to make batches of these metals now that involves an arc welder of vacuum chamber and inert gas and the molds are super cooled copper molds.
This is a very interesting pour! That smaller one that you cut in half would make a couple really nice pens. Although I would have to use my cousins large metal lathe as my small mini metal lathe would not touch it. Using some ebony accents to highlight the metal. Liked and subscribed.
Thanks for the sub Dirk, glad you enjoyed it mate... Andy 😎😎😎
I would love to have an ingot of this. Not sure what I would decide to do with it, since I have a lot of ideas for ways to use it.
exactly what I wanted to see great testing on this metal alloy is it light or much the same as copper I'd suspect looks like a great one with sword making or tools really enjoyed this mate another like bro greeting by another metal casting tuber!
