Copper nickels.

Adding nickel to copper improves strength and corrosion resistance, but good ductility is retained. Nickel Silver. Nickel silver, also known as German silver, nickel brass, or alpaca, is a copper alloy with nickel and often zinc. For example, UNS C75700 nickel silver 65-12 copper alloy has good corrosion and tarnish resistance and high formability.COPPER ALLOYS High Coppers - 90%+ (C1xxxx) 225 Brass (Copper Zinc alloys, C2xxxx, C3xxxx, C4xxxx, C66400-C69800) 500 ...
