The C954 aluminum bronze I use to make axe blades has a slight attraction to magnets, but it also has a small percentage of iron in it. I do not believe it would be magnetic otherwise. I look forward to seeing you try heat treatment hardening with your diy alloy! That is something I have always wanted to try with the purchased alloy I've been using. If only I had a controllable kiln... However, aluminum bronze blades will still work harden quite well with a bit of peening. Try dropping one of your ingots on a cement floor or hitting it with a hammer. Watch out for shrapnel though; if you have too much aluminum in it, it will be so hard and brittle that it shatters like glass!

Cast iron Is usually steel. The carbon content is higher than most steel alloys. Cutting the iron into smaller pieces may help them melt easier

The alloy mix with iron should yeild good results for being heat treatable and tempered. Never tried it myself. Plain-jane AlCu is still a useful, extremely hard alloy. Great video.

Merry Christmas. Great experiment. looking forward to seing how you make out

I'm amazed your furnace didn't melt into a puddle haha Would love to try gas furnace one day, they look a lot more fun than the small electric one I use!

Great video. Thanks. 👍👍👍

Very nice!

Hell yea man keep it up 🤙🏼

Interesting stuff. All I can say is when they make steel, they throw the alloying elements in last. You might need to melt the iron, then add the copper, then the aluminum right before you cast. Stirring might help. Good luck dude.

To quench harden aluminum bronze you make sure it’s over 15% by weight no need for the iron

To lower the melting point of iron so you can accomplish this at home simply add phosphorus

Al Bz should NOT be ferrous (magnetic). BUT the max ratio you're supposed to mix it is 90% Cu / 10% Al, otherwise it gets brittle as heck.

Yes the aluminium is what makes them mix

I believe iron is supposed to be added last in aluminium bronzes

How much for one of those hearts

Great Video! Is that a 6kg crucible you're using in that propane burner?

Where is the blade?

ok, can we promote the ONLY one american youtuber who said it outloud? METRIC SYSTEM IS EASIER! :P switch to celcius instead of farentheit and that would be all ;) (as for lbs you too prolly saw on others channels they just slap other measirung system values on screen, and you clearly know how to do notes on screen :) )
