I was wondering about the colours of molten metal as i only melted aluminium . And on channels i follow the copper and brass colours are different. Although with my flames in furnace it gets hard to see until it settels.
We aren't sure about the density, however aluminum doesn't distribute heat as well as iron or steel. In both cases we are avoiding blowing out metal, so maybe it has to do with weight as well. If anyone else watching is a seasoned welder and knows the answer feel free to chime in.
Hey man I hope you can help me here* I need to seperate gold from a mix of iron nickel silver gold alloy* I plan to melt it down in an induction furnace and pour it into a pyramid slag mold* and collect the gold at the bottom* could you advice me on this
I'm sorry Mohd, for something that specific we would recommend connecting with a metallurgist. While we created this to give our customer a general understanding of melting points the details you are requesting are far more scientific.
Your videos are really a informative. It would be great if you tell me the thermo-physical property of grey cast iron. properties like solidus temperature, liquid temperature, latent heat of fusion, thermal conductivity ant etc..
Hi Biniyam, for something that specific we would recommend connecting with a metallurgist. While we created this to give our customer a general understanding of melting points the details you are requesting are far more scientific and detailed.
Hi my question is how can I make a steel shot maker similar to a Oasis Lead shot maker. Waterfowling requires non-toxic shot and steel shot, bismuth, tungsten or copper plated shot is required. How could I make my own shot maker for hunting and just plinking at the range? Each pellet has to be perfectly round
That would be a very difficult project due to the significant temperature needed to melt steel. Lead melts at a low enough temperature you can easily make shot in your home using something like the Oasis. Steel, on the other hand, requires a lot more energy to get that hot, and you also need the tools to be made from sturdy enough stuff to reach that temperature without melting. One of our employees' brothers made steel shot a few years back and said it was too much effort to replace just buying steel shot.
Each alloy can have different melting points, but the spreadsheet in our description gives a pretty clear picture of the base metals and their melting points.
In general, metal will melt at a lower temperature in extreme pressure, however, there are plenty of variables to consider when it comes to each material.
@@Jkauppa that is a bit over our head, while we know that carbon is the highest of any element in melting point, we can't confidently tell you if it would melt with just friction pressure melting. Sounds like a great test case.
hi, I got a question about melting alloys, say for example I had a 6061 aluminum alloy and I decided to melt it at 2000°F does it still retain it's properties when it hardens?
Hi Louie, the short answer is no. The 6061 we stock is strain hardened, tempered and sometimes stress relieved. It will have vastly different properties. Also 6061 isn't great for casting if that is what you are looking for.
Oh thanks for the reply, so what kind of aluminum is suited for casting? say I'd like to make a plate with a thickness of 20mm that I would machine later on
@@onlinemetals I see, the problem here in my country is that I couldn't find a local store that would sell aluminum plates that's why I decided to build my own foundry, the only part I'm missing right now is the knowledge of creating a plate, I don't know maybe I can weld my own mini cold roll forming machine or do you have any ideas to at least make an aluminum with less porosity?
Unfortunately, that is a little out of our realm. Might be worth heading to our site and chatting with our team or reviewing our product guides to help you through your decision: www.onlinemetals.com/en/product-guide.
When you heat something it puts of EMR. ie. warm metal plate at 100F will feel hot to touch yet look silver. Its putting off infrared which is outside of human visual spectrum but not outside a properly made detector. The peak is usual in the IR range till you heat it enough where it starts to peak at shorter wave lengths, it begins to spill into the shorter infrared part of the spectrum to visible red. the first redish glow of hot iron at around 900F. Keep going and the spectrum shifts till its in the middle of the visual spectrum appearing white hot then shifts to shorter blue wavelengths. physics.stackexchange.com/questions/304299/how-heated-metal-colors-relate-to-black-body-color-at-the-same-temperature Take a look at the graphs on that page. People can get pretty good at guesstimating a metals temperature via apparent color not quit as accurate as a prism spectral analysis though. This is not a bad starter on it if you want to get into a little more. web.iitd.ac.in/~sdeep/Spectroscopy_lecture_1_2.pdf Enjoy!
I used a stainless steel pool filter filled with hardwood/charcoal lined with fire brick and fed with one of those cheap air blowers made for bathtub mats. Had fun melting aluminum but was surprised to find out I had melted the iron hinges from the hardwood table. Not bad considering no extra oxygen was added.
Our guide online should provide some guidance on that matter: ruclips.net/user/redirect?q=https%3A%2F%2Fwww.onlinemetals.com%2Fen%2Fmelting-points&event=video_description&v=0qMIL3NPW1w&redir_token=39A3TbubeZX8eiEI-8znbDK5FkB8MTU3NzgzMTY1MEAxNTc3NzQ1MjUw
Hi Darren, it has to do with the chemical makeup. Copper is used more frequently for electrical and thermal conductivity than silver so it needs to maintain its form at higher temperatures.
Sorry wrong on color and melting point. Its based on temperature black body radiation. That is one of the reasons why aluminum is silver looking when it melts + reflectivity When it does get reddish its much hotter than melting point and is why iron is just as red yet a solid.
A 304 will maintain its shiny appearance over time and will be easier to clean, but 430 will be a much cheaper and stilll effective grill. Hope that helps!
We hear you loud and clear. Definitely on the horizon to do one for Celsius or include both. We have a table in the description above that can show you the comparison.

When welding why is a blowout of aluminum more catastrophic than steel? Does the density cause greater heat distribution?
We aren't sure about the density, however aluminum doesn't distribute heat as well as iron or steel. In both cases we are avoiding blowing out metal, so maybe it has to do with weight as well. If anyone else watching is a seasoned welder and knows the answer feel free to chime in.
@@onlinemetals that makes sense. Steel can distribute heat faster so the blowout doesn't get as bad as fast as aluminum. Thank you.

Can you change melting point any matel?
Each alloy can have different melting points, but the spreadsheet in our description gives a pretty clear picture of the base metals and their melting points.
Yes, of course all metals have different melting points but for example tin melting point can go to silver?
Your videos are really awesome, very informative. It would be great if you make heat treatment of steels :)
Thank you! We will definitely look into making a video regarding the heat treatment of steels.
Quick advice use C as Celcius universal unit so we all can understand
Definitely agree! The focus here was definitely US based, however we do have comparisons to Celsius here: www.onlinemetals.com/en/melting-points
Better yet, let the Celsius people learn how to convert from Farenheit to Celsius.
Hey can you plss tell me how to lower the melting point of steel by simply adding chemicals.
Not sure what the ask is here, but alloying material is a sure-fire way to affect the melting point of steel.
how does high pressure (megapascals) affect melting points of metals?
In general, metal will melt at a lower temperature in extreme pressure, however, there are plenty of variables to consider when it comes to each material.
@@onlinemetals if you friction pressure melt carbon, assuming no leaks, would it work?
@@Jkauppa that is a bit over our head, while we know that carbon is the highest of any element in melting point, we can't confidently tell you if it would melt with just friction pressure melting. Sounds like a great test case.

@Nathan Cassius no problem =)
Wow amazing 😍😍😍 this to all colour Metall i like thank your
In btw Tungsten where am I ?
Hi there, we focused on materials we sell and the different alloys that could be impacted.
What of metals like Tungsten and titanium?
Our guide online should provide some guidance on that matter: ruclips.net/user/redirect?q=https%3A%2F%2Fwww.onlinemetals.com%2Fen%2Fmelting-points&event=video_description&v=0qMIL3NPW1w&redir_token=39A3TbubeZX8eiEI-8znbDK5FkB8MTU3NzgzMTY1MEAxNTc3NzQ1MjUw

Glad you like it! Hope you have a new appreciation for both metal and the extreme temperature and pressure it goes through.

Hi there Bob! Could you walk us through black body radiation and how that impacts color a bit? Love to hear more about your insight.
The fact core was right, tungsten has the highest melting point of any Metal.
Hi there, we focused on materials we sell and the different alloys that could be impacted.
Precious metals ???
We focused more on the materials we actually sell, but our table in the description may have a few of the precious metals you are looking for.
