Copper Nickels

Copper Nickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. It is highly resistant to corrosion by salt water, and  used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is also used for the propellers, propeller shafts, and hulls of high-quality boats. Other uses include military equipment and chemical, petrochemical, and electrical industries.

Copper Nickel 90/10 alloy has high resistance to stress corrosion - erosion in seawater and good weldability. Its combination of good ductility retention and thermal conductivity at very low temperatures.
