CMW 3950 is a tungsten bearing sintered alloy of high density and high strength. It is a powder metallurgical product and one of a series of alloys with densities 50% greater than lead. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive and bend strength as well as fracture toughness and fatigue. It also includes information on high temperature performance and corrosion resistance as well as machining and joining. Filing Code: W-11. Producer or source: CMW Inc. Originally published as Mallory 3950, March 1968, revised September 2000.

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.

ELKONITE 1W3, 3W3, 3W53, 5W3, 10W3, 10W53, 30W3, 40W3, 50W3,and 2050C are a series of tungsten-copper compositions with the tungsten content ranging from 50 to 90 wt.%. These alloys are normally made by the press-sinter-infiltrate (PSI) method. This datasheet provides information on composition, physical properties, microstructure, and bend strength. It also includes information on heat treating. Filing Code: W-25. Producer or source: CMW Inc.

UGIMA NSU and UGIMA 303 are the same grades designated differently for the European and North American markets, respectively. They are resulfurized grades with calcium added. Carefully controlled steelmaking results in a composition with oxides that have a low melting point and produce a lubricating effect during machining. Gains in the cutting conditions of 25 to 50% are typical on computer numerical control (CNC) lathe or classical machine work. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-709. Producer or source: Ugine-Savoie.
