CMW 3 is an age-hardenable copper-base alloy combining high mechanical and electrical properties. The alloy is typically used for spot and seam welding cold and hot-rolled steels and coated materials, current carrying shafts and arms, back-up bars, back-up bars for arc welding, electrical current carrying structural parts, and springs. The alloy is available in both the cast and wrought forms. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: CU-85. Producer or source: CMW Inc. Originally published as Mallory 3, January 1960, revised August 2000.
