ABSTRACT:
Method for producing extruded structural profiles from aluminum or aluminum alloy scrap materials. The scrap materials are compacted under room temperature or under heat suitable for hot extrusion into a cylindrical body which is of such a dimension that is suitable for insertion into an extruder. The compacted body has an average density which is 70 to 86 percent of that of aluminum, and includes longitudinal air passages. Suction pressure is applied to the interior of the extruder during extruding process for removing air entrapped in the body, which may otherwise cause voids in the extruded products.
