When I get my foundry built I will probably melt some of that extruded AL but what I will be melting and casting the most will be Cast AL.
I also will be casting a lot of cast iron.
Pop/soda and beer cans here are worth $0.10 each and I truly doubt there is a bucks worth of AL in ten empty cans melted.
