<p>A method of segregating metallic components fabricated from different aluminum wrought alloys comprises the steps of providing a feedstock such as used aluminum containers having at least two components thereon comprised or different aluminum alloys and heating the feedstock to a temperature sufficient to increase the fracture sensitivity of at least one of the components. Preferably the temperature is sufficiently high to initiate incipient melting of the component having the lowest incipient melting temperature. While at the lowest incipient melting temperature of the aluminum alloy component, the feedstock is subjected to agitation sufficient to cause the aluminum alloy component having the lowest incipient melting temperature to fragment and, when part of an article, to detach itself from the article. Thereafter, the fragmented or detached components are segregated from the remaining components or articles and may be recovered.</p> |
