ZA-12 is the intermediate member of the family of three ZA die-casting alloys. Its melting point, solidification range and recommended casting-temperature range are greater than those of ZA-8. (See Alloy Digest Zn-48, January 1990). Due to these factors, ZA-12 must be die cast in cold chamber die-casting machines like conventional aluminum die-casting alloys. 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-49. Producer or source: Aluminum Smelting and Refining Company Inc..
