A high strength copper alloy composed of over 70% copper and remainder of Sn, Fe, Al, Mn, and Ni. The alloy has double the compression strength as compared to SUS304 stainless steel. Copper alloy parts can be formed by die casting or by precision casting. The material has good compression strength, yield strength, and machinability. Also, the metal alloy can have a thin profile (thickness) and is excellent for plating, PVD coating, and other surface treatments. Applications include industrial and consumer good components, such as metal credit cards, smartphone frames, and hinges.
