Abstract
An improved aluminum alloy containing specific additions of silicon and copper to improve wear resistance and improve solutionizing of the alloying constituents, and a process for forming a wear-resistant component from the alloy. The improved aluminum alloy is also characterized by good strength and sufficient ductility so as to permit forging of a wear-resistant component from the alloy. A preferred composition for the alloy, in weight percent, is about 13.0 to about 15.5 percent silicon; about 0.8 to about 2.0 percent copper; about 0.8 to about 1.3 percent magnesium, and the balance being aluminum and impurities. The aluminum alloy is particularly well suited to form pistons of the type used in compressors of automotive air conditioning systems.
