ABSTRACT:
A method of detaching and segregating metallic components secured to metallic articles is disclosed. The segregation is made in accordance with the alloy composition of the components. The method comprises the steps of providing articles having at least two components thereon comprised of different aluminum alloys and heating the articles to a temperature 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 articles are subjected to agitation sufficient to cause the aluminum alloy component having the lowest incipient melting temperature to fracture and detach itself from the article. Thereafter, the detached components are segregated from the remaining articles and recovered.
