This has to be the first video I've watched of someone pouring brass where there isn't huge billows of zinc boiling off the top. I think the method of disolving the copper in molten zinc was the trick, a new method to me. It would be interesting to know the temperatures you're working at. Thanks for the video. Excellent as always.
The copper starts to "dissolve" (not sure this is exactly the correct term) at about 1500 F then we pour about 1850 F or so. Keep the temp around 1500 until the copper is all in and then raise from there
@@mbmmllc I was looking into making brass today and was asking around about how to avoid issues with the low boiling point of zinc. Thank you SO much for posting this video!!! Quick question...once it's actually poured and cooled and the alloy is fully formed at room temp...are there any further concerns for re-melting the alloy? Like...will the zinc potentially separate in the molten state and start boiling?
Wow thanks a lot! I remember the definition of Alloy and the most used example of it was Brass. I thought to search on RUclips and see if I was lucky enough to see it live and here I have it.
I've tried this method and made 50-50 copper zinc brass, which is yellow and looks a lot like gold. Thanks a lot for the tip. Before i was putting zinc in molten copper and it was not good (zinc oxyde fumes are not nice to inhale : metal fever). In fact copper does not dissolve in zinc. Zinc diffuses in copper and transforms it into brass. Some copper also diffuses into the zinc. The new brass melts down and then you can increase the temperature above 900C without the zinc boiling.
It is very important to cut the copper into very small parts to increase the copper surface and the speed. I have made my brass at 600C first, then 750C, then 1100C for pouring.
Thank you for this information, I am currently trying to mix Cu and Zn and it makes lots of smoke but it is precisely because I raise the temperature to quickly
@@TheBruzka Be careful with this smoke. It is zinc oxyde. Don't breathe it, it causes zinc fever, a flu like condition. Kind of allergy. Zinc boils at 910C, you need to start much lower. Check the temperature with a 1300C infrared thermometer.
I used a long pliers to hold a six-inch zinc billet in the flame until it dripped molten zinc into the melted copper in the crucible. I lifted the furnace cover and quickly stirred the hot billet into the melt. Lots of smoke, but the repeated process produced beautiful 60/40 brass with only about 6% zinc loss.
We have several tons of brass scrap turnings generated from our CNC machines ...But never tried melting of brass. Well awesome and easy process. Praveen Gupta , India
very informative video۔ few questions i want to ask that you mentioned that you added aluminium into the molten copper and zinc but you didn't told when you added and if we want to add more aluminium like 7% ? Further more can you tell how to add iron into this brass? and the last question is I also want to add 3% manganese in the brass, what temperature we required? My target is to make brass with following composition Cu 68% Zn 24% Al 7% Fe 4% Mn 2%. I hope to get some supportive response. Thank you
I'm an artist. I'm thinking of mixing copper and zinc pennies together to make brass. You have any suggestion what temperature to set the furnace to ensure complete mixing without boiling the zinc?
How will this brass act in quality? Will it be just as fresh as "new brass"? Or will the material loose its strength after every time it is smelted? Thanks for video. Planning to make a staff of wood and a stone at top, and I wish to use metal to fasten the stone to the stick. First wanted to use silver, but it's gonna cost me much. So I beleive brass is going to be great.
Hello . I usually base 300 grams of copper and a few grams of zinc. I have noticed that the zinc added to the molten copper burns. I would like to know if the right sequence to prevent zinc from burning is the one in the video and if it is also good for small quantities of brass
Not sure about the specific types of brass for electrical contacts. I would do a quick google search and it would tell you the type of brass used. There are lots of different types of brass. Most are between 60%-80% copper with other additives depending on the use
Well that was a nice video but the ending was a bit disappointing it would have been nice if you would have took at least one bar and shined it up so we can see what it look like it wouldn't have been that hard come on guys and tell me how much do you sell one bar like that for just curious cuz I could use some

What are you trying lol
I'm suddenly in love with chemistry after screaming at my chemistry book for an hour, great video

@@puits-de-science I already had the fever, with a headache … my body expulses that, right?
@@puits-de-science what is the white powder that sticks to the surfaces? Pure zinc?

That's pretty incredible! Those brass bars look amazing!!!
Super beautiful!
Thank-you!
You should do a video of the separation of copper and zinc from brass! Seriously, though, I can't find one video on it
I would love to be able to melt my own brass ingots and be able to fabricate my own brass fittings. I spend too much money on brass!
I scrap metal and I was drooling over this video haha
Haha, thanks for watching
Those ingots are gorgeous. Nice job👍👍👍
I absolutely love copper alloys!
TAKE IT ON THE RUUUUUN BABY
Very cool.... I am going to show this in my Science class tomorrow.
Nice work, guys!
Wow! Thanks for sharing this. Very interesting/educational.
Love watching smelting vids. 🍻👍
Is that an induction furnace? I always thought copper was too conductive to really work in an induction furnace. I guess I learned something.
I'm searching this video 🎉 I like this .Awasome
Love that Take it on the run by speedwagon is playin in the back lol
Any chance to buy brass from you at larger volume?
i have a silver coated brass fountain pen therefore i looked this up. (the pen is labam antique)
Love your work nice neat and clean

This mixture of copper and zinc. Could it be malleable? I mean soft copper

Dude, i think that's gonna look pretty awesome!
@@jordazmo19 hoy. Cool, I will make a video upload once I get further into the process
Did you stir the melt or did it mix by itself? Great video. Thank you.
What type of furnace is this? Can you share the details?
Now, can you make bullet casings out of some brass ingots?
great job well done guys
would yu know in 1800 how was zinc purchased? by brass makers.. was it in ingot form? especially if yu could know wrt india
I think we mix with iron content also
Does that alloying process create slag just like melting alumunium and steel making?
Hi there. This is so cool. Can I use this video for my compilation about amazing workers and tools? I'll give you full and proper credits. Thank you.
Want start my own brass foundry

Does it dissolve ? I thought it melted .....
wait, isnt brass made out of gold too?
Keren masheeeee from indonesia
Great video! Do you coat the ingot containers with anything to prevent the ingots from sticking?
Nope, just cold, but dry steel. Knock them out before they cool all the way
Can u tell instrument used to check percentage of metals ??
Does this zinc puddle method really works?
brazing rood কিভাবে তৈরী করবো..?
Very helpful video. May I know which instrument you used to measure the metal ratio?
It looks like a Niton XL2 from Thermo Scientific
How many percent of copper and zinc? How much burning lose of it?
Thought brass was tin and copper? Is tin and copper bronze instead of brass?
Tin and copper is bronze. 20 -25 percent tin is ideal for casting 🔔.
After read the book I am here
very helpful video
Well that was cool.
how would a brass pewter work for jewelry
What is the ratio of metal used to making brass Spatially used for electrical contacts and connecting foils .
Not sure about the specific types of brass for electrical contacts. I would do a quick google search and it would tell you the type of brass used. There are lots of different types of brass. Most are between 60%-80% copper with other additives depending on the use
What thype of melting technique is that plz can someone tell
Is 1.2 % of lead normal in brass utensils ?
WHAT CAUSES BRASS TO HAVE PITTS OR BUBBLES IN IT?
Cool
What is that gun that you used at the end? How does it work
XRF GUN works by magic
What is proportion??
What happened if I mix 30% copper & 70% zinc , please reply
you get wrought brass. Google is your friend.
Per kg how much price
Ciao una domanda ma e oro giallo
how to saperate copper and zinc
Bhatti ke bare jankari chahiye
Not bad!
Can you use aluminum instead?
That would make aluminium bronze.
Yes for aluminum bronze. only about 5% aluminum and 95% copper though
Can you please tell us what is the ratio of copper and zinc
about 60% cu and 40% zn
Super
