I'm confused on something, maybe you can clarify. I been stripping motors with the air chisel, since steel is hard to find atm, Some are aluminum with copper coating. You know the kind where it looks like copper, but aluminum in the middle?



Anyway I have been throwing it in with the cast aluminum.

Have I been paying idiot tax? Should this actually be copper/alu and go in with the ac condensers, rads, etc?
