Melting aluminum?

Question

im melting aluminum and what should i use for metal. cans will just oxygenize( i forget the word for it sorry)

Answer 1

aluminum, in general, will just oxidize if heated in air.  it is not just cans that behave that way

when they (alcan, alcoa) smelt aluminum industrially they keep it in a reducing environment and do not allow molten aluminum to contact air.

so use any aluminum you like but prevent it from contacting air.
