Cupro Nickel 70/30 Flanges Corrosion Resistance

Cupro Nickel 70/30 flanges offer exceptional resistance to corrosion in seawater, brine, and other corrosive media. Its strong resistance to biofouling and enhanced resistance to crevice corrosion and impingement attacks make it an ideal choice for marine applications. Raw seawater and marine environments containing hydrocarbons, chlorides, and sulfides are aggressive environments that can quickly deteriorate metallic materials. However, Cupro Nickel 70/30 flanges offer high resistance to these aggressive environments and provide extended service life.
