Copper Alloy No. C94300 is a cast copper-tin-lead alloy (bronze). It is characterized by low hardness and strength, medium ductility, excellent machinability and good resistance to corrosion. Commercial names formerly used (but not recommended) are (1) Ingot No. 322, (2) Soft Bronze, (3) High-Leaded Tin Bronze and (4) 70-5-25. This alloy is recommended highly for high-speed bearings at light loads. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-470. Producer or source: Copper alloy foundries.
