AMPCOLOY 97 is a high-conductivity alloy in which medium hardness and strength are provided by age hardening. Its applications include such items as current-carrying rings, water-cooled casting molds, bushings and bearings. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as machining and joining. Filing Code: Cu-321. Producer or source: Ampco Metal Inc..

AMPCOLOY 91 Alloy is a cobalt-bearing copper alloy with a small addition of beryllium to make it age hardenable. It has an excellent combination of strength, toughness and electrical conductivity. It is recommended for resistance welding tips and wheels; flash, butt and projection welding dies; springs; slip and collector rings; and electrical components. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting, forming, heat treating, machining, joining, and surface treatment. Filing Code: Cu-286. Producer or source: Ampco Metal Inc..

AMPCO 940 is a precipitation-hardening copper-nickel-silicon-chromium alloy developed for resistance welding and other applications now using the 1% beryllium-copper alloys. The heat-treated alloy is capable of meeting the RWMA (Resistance Welder Manufacturers Association) Class 3 minimum requirements-95,000 psi tensile strength, 90 Rockwell B hardness and 45% IACS electrical conductivity. Potential applications include resistance welding tips, wheels and fixtures. A major use is in plastic injection molding. AMPCO-TRODE 940 is used for repair welding and overlays. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as casting, forming, heat treating, machining, and joining. Filing Code: CU-434.
