Abstract

Copper Alloy no. C90500 is a cast copper-tin-zinc alloy known also by names formerly used (not recommended): Gun Metal, 210, Tin Bronze and 88-10-0-2. It has a good combination of strength and resistance to corrosion. Because of its mechanical properties and corrosion resistance, it is used frequently in castings that are subjected to liquid or gas pressure, such as those in valves, pumps, etc. It also is used for bearings and gears. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-432. Producer or source: Copper alloy foundries.
