Copper No. C81100 is a cast copper with relatively low room-temperature strength and fairly good ductility. It has good thermal and electrical conductivities and good resistance to corrosion and oxidation. Its characteristics make it highly suitable for applications that require good conductivity and good resistance to corrosion and oxidation. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting, heat treating, machining, joining, and surface treatment. Filing Code: Cu-515. Producer or source: Copper alloy foundries.
