ZA-8 is a hypereutectic zinc-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. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming, machining, and surface treatment. Filing Code: Zn-48. Producer or source: Aluminum Smelting and Refining Company Inc..
