Copper-Nickel Alloys

Complete solubility occurs between copper and nickel. All alloys have similar microstructure and can be cold or hot worked.
Cupro-nickel also known as German silver is extremely malleable and ductile. It is good against corrosion due to salt water. Condenser tubes are main parts made out of this alloy. It is also used for coinage. 70/30, 80/20 and 75/25 alloys are very common.

Monel metal is essentially 70% Ni and 30% Cu with small amounts of iron and other elements. Alloy is well known for its high strength and corrosion resistance. This alloy is largely used for chemical and food processing plants. It also finds great use as turbine blades, valves corrosion resistance bolts, screws and nails. It is known for its characteristics silver luster.
