3:10 you should are to the heavy side with the aluminum because you'll lose some of it

What is ratio of copper and aluminum

is same like EU coins 10 and 20cent 50cent

You really should melt the higher temp metal first, then add the lower temp stuff to avoid overheating the shit out of the lower temp metal for ages.

it is easy to burn the metal so watch out on the heat if you can pull it off place a ir reader close so you can read the level of heat .. also never use dryice it will warp the metal unless you have it in a 2+ ton press .

Your text Nick leaves a lot to be desired sorry this is way too immature

👏👏👌👌

Fresh sub, thanks for the stream!! But, i cry over the melting of bar stock copper. 😢 😊

yeah man that was a great session , great big bar there love the sand mixing I need to pour a big one in a sand mold on my channel , I did a Nordic gold couple weeks back still waiting on more tin to arrive as well sub you another like on e mate !

I suspect this may be the most useful new to me alloy yet? I was not introduced to it by you, here. It was in fact BigstackD with Nordic gold. But it turned out not to be a cheeky gold imitation I discovered later. It is a precise ratio that provides a strong, possibly enduring material supplementing naval bronze? Only now I wish I had not sold my leather motorcycle jacket. It would have been a great safety garment to wear when casting copper alloy.

Is that an airplane at the end? I put on my earbuds to listen more. Can you describe what kind of sound it was? I find this fascinating and I'd really love to try and work it out. I am struggling to differentiate between your movement.

Nice video - thanks. Water quench from near melt temperature - I wonder what the metallurgical structure looks like. Can any metallurgists answer that?

I have a question can u melt copper,brass, aluminum, and dust like iron to make a sword ive always wanted to make a sword of stainless steel, copper and brass but aint found anyone thats done it yet could it be possible

far out

Maybe put the lit paper in the bottom part to get it started.

Will a 30% copper 70 % aluminium alloy work for casting a cannon? I want to use this low temperature eutectic....

Excellent question, how long does it take to melt?

Great work 👏

I need to build one of these as a beginner project or something, the schematic looks fairly simple

I was successful in making the aluminum bronze, however my furnace don't want to remelt the bronze. Any idea why?

Your math is rotten.

why 11% al and 89% cu? can you do it 50/50?

Where did you get the plans? I like the big one.

What size is the crucible your using in this video ?

so its basically brass useing aluminium instead of tin

she's a lucky woman

Can you do some small ones and add small amounts of other alloying elements metals or nonmetals in Trace Amounts like 1- 2% give or take and tweak the recipe for better grain size or Surface texture or to make it more cold workable to be made into jewelry things like tin zinc lead magnesium beryllium business silicone phosphorus or anything else to improve on that. I've done lots of homework and would love to help you brainstorm on such a project if you're interested and I don't have my notes with me or I would have included more specific recommendations but would gladly dig them up if there's any potentials future in pursuing that with you because I don't have a Forge as I'm working on a shoestring budget that I do have plenty of time and motivation and more than enough intellectual capacity to dedicate to such a task if you're interested and as far as being able to cold work the material I think annealing would be a much better choice than quenching and allow you to successfully stamp it for better results. Quenching increases hardness and tensile strength while annealing increases malleability it's just the difference in how the crystals form their lattice under different conditions

Put that thing on a grinder or sander and progressively move up to a buffer and polish it up real nice but after you pour it is there a way you can reheat it while still in the mold to smooth out all of the rough spots because I've seen that done with silicone molds and Kilns with gold which eliminates all of the concentric rings on the top and stratification on the bottom for a much nicer looking ingot that doesn't have to be grinded or sanded as much and lot less work I think for a nice looking end product

The heat comes from outside of The Crucible and copper has a lower melting point Than The Crucible or it would shaped very differently now but either that's copper inside of your Crucible still or somehow the inside of The Crucible which was the furthest from the heat Source managed to get hotter than the outside which makes no sense at all so how do you clean that mess out of your Crucible after it cools?

I've been looking at things like Nordic gold but I don't think they're going to do what I need them to do so I'm leaning towards aluminum bronze now and looking for ways to alloy it with other things to make it more manageable through cold working processes that could allow it to be more practical for making jewelry when alloyed with gold at low karat amounts like 6K (25%) because people still want gold jewelry but can't afford 14 karat or 18 karat so if anybody has any recommendations on any metal or nonmetal Alloys that could suit my needs I think affordable low karat gold jewelry that retains all or most of the qualities and characteristics of higher karat gold jewelry looks appealing to me as very marketable.

Do you glaze your Crucible with Borax or anything else before using it the first time?

The concept of these timers makes my brain go crazy! Love them but no sure why yet hoping to make something interesting from them one day

The EASY way to figure percentage weights from a "I'm gonna use this pile" start (doesn't matter major, minor, or trace ingredient): weigh your "start pile" (your 2 copper bars). Divide that weight by percentage of total (89). Result is 1% weight. Multiply by additional ingredient percentage (11 for your aluminum), result is needed weight for that ingredient. Write down weights of each so you can "check sum" on the scale. By working from 1% weight, even "points' (nn/100 of a percent) are easily determined (0.nn times 1% weight). At any point you can confirm the result by dividing by "accumulated percentage" to ensure it conforms to the 1% weight. Best part is it doesn't matter what your "starting pile" is, the major ingredient, or the most minor one, or any in between.

Great work! How did you add the engraving?

Good stuff. New subscriber. You from TN?

Hey there, old video but how did you create the base/legs?

Queria entender porque colocar o metal com menor ponto de fusão primeiro e não o contrário. Não há perda do alumínio por evaporação? Obrigado

How do you figure out aluminum to copper . What is the ✍🏻formula to get 89 aluminum to 11 copper. I tried I got it way wrong 👎🏻

place crucible on plinth block with cardboard separating the two and you will get better melts with less crucible stick. Clean bottom of crucible

So its an electronic fart generator?

👏👏👏👏👏🇧🇷🇧🇷♻️♻️

I want to make stuff out of bronze I'm hoping I can figure out a way to make a statue mold

That was pretty cool man👍

How strong it is compare to bronze or brass?
