ZAMAK 3 is the most widely used general purpose zinc-base die casting alloy. It provides an excellent combination of strength and ductility. It has good impact strength. It is the designer's first choice for die casting applications. This datasheet provides information on composition, physical properties, hardness, 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, heat treating, machining, and joining. Filing Code: Zn-1. Producer or source: Noranda Sales Corporation.
