Copper Alloy No. C96600 is a cast copper-tin-lead-zinc alloy also known as 87-10-1-2 alloy. It is characterized by a good combination of strength, machinability and resistance to corrosion. This alloy is often used to make castings for valves and pumps which are subject to liquid and gas pressure and, therefore, must be free from internal porosity, shrinkage or other defects. 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-410. Producer or source: Copper alloy foundries.
