Copper Nickel alloys have excellent resistance to seawater corrosion and are widely used for marine application. They have excellent inherent resistance to biofouling and good fabricability. Often used in pump components, oil refining, condensers, heat exchangers, salt water piping systems, and various marine hardware components.
