View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.ZA-8 is a hypereutecticzinc-aluminum,highperformance die casting alloy. It is one of a family of three ZA Alloys which can be economically die cast with properties surpassing conventional zinc or aluminum alloys. It is the lowest aluminum content alloy of the family and it has the lowest melting point and casting temperature range.
