Abstract
A continuous process is disclosed for the recovery of an aluminum alloy from aluminum scrap containing more than one alloy. The recovery is made in a manner which will conserve energy. The process comprises providing a feedstock containing at least two components therein comprised of different aluminum alloys, the components having at least parts thereof joined to each other. The feedstock is treated to cause the joined components to become detached from each other. One of the detached components is separated from the remainder of the feedstock, melted and thereafter continuously cast without substantially upgrading the composition thereof to provide a cast alloy having a composition substantially the same as that from which the separated component was fabricated. The treating may be accomplished by heating the feedstock to a temperature sufficiently high to render fracture sensitive the component having the lowest incipient melting temperature.
