CMW 28 is a copper-base alloy having exceptionally high electrical and thermal conductivity coupled with reasonably high strength and hardness. Typical usage is for the spot welding of coated steels and high-conductivity materials, excluding copper and silver. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: CU-97. Producer or source: CMW Inc. Originally published as Mallory 28, February 1961, revised September 2000.
