When you throw them on the truck keep them separate. They are handled
differently at the scrap yard.

Thanks everybody for encouraging me to take my scrap aluminum siding to
the metal scrap dealer (instead of my wife's kiln). I also have been
saving aluminum window frames, screen door frames and ladders. Are these
also not ideal for foundry work? Should I throw them on the truck?

Thanks again,
