DI-METAL 3 is a zinc-base alloy of high fluidity capable of producing fine detail in die castings. It is the most stable of the zinc die casting alloys, but on aging loses about 20% of its tensile strength with practically no impact drop. This datasheet provides information on composition, physical properties, hardness, tensile properties, and shear strength as well as fracture toughness. It also includes information on corrosion resistance as well as casting, forming, heat treating, machining, and joining. Filing Code: Zn-3.
