Abstract
Wrought aluminum alloys are separated from cast aluminum alloys. The former are primarily aluminum, and the latter contain at least 1.5 pct silicon. The scrap mixture is heated to a temperature (550 deg-580 deg c) above the solidus temperature of the cast scrap. The mixture is crushed, and the cast alloys are fragmented. By using an appropriate screen, the cast fragments are separated from the wrought aluminum alloy pieces, which are merely flattened. The method is useful in the secondary aluminum industry.
