Copper-nickel alloys | Nickel Institute

As with other nickel-containing alloys, 90-10 and 70-30 copper-nickel alloys rely on a protective surface film to maintain their corrosion resistance. However, they differ because the protective films result from a reaction with the seawater itself, rather than the oxide film formed in air, and are a complex and layered mixture of oxides, chlorides and hydroxy-chlorides. These protective ...
