Tg-12 Zinc Alloy is the general-purpose, zinc-aluminum-copper foundry alloy. It can be sand, permanent-mold or die cast, has a modest cost and a tensile strength suitable for many applications where bronze and cast or malleable iron were traditionally used. Tg-12 is extremely resistant to galling, has natural lubricity and is thus well suited to lubricated bearing and bushing applications. Tg-12 is particularly well suited to liquid and gas-pressure applications. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness and fatigue. It also includes information on casting, forming, heat treating, machining, and surface treatment. Filing Code: Zn-37. Producer or source: Texasgulf Inc..
