Widely used in marine applications where resistance to both corrosion and biofouling is important. C715 Cupro-Nickel is a 70/30 copper-nickel alloy that is almost entirely resistant to stress corrosion and is ideal when used in applications involving high-velocity polluted seawater. Typical 715 CuNi applications for use in the chemical and desalination industries include tubes and tubesheets for condensers, evaporators and heat exchangers; tubes for carrying seawater; valve bodies; pump bodies and impellers.
