This paper examines surface films, localised corrosion, sand erosion, galvanic issues, sulfides and ferrous sulfate treatments as well as biofouling, boat hulls and offshore sheathing.In principle, a cupronickel can contain between 1% and 49% nickel, such that copper remains the main element (otherwise you would call it a nickel-copper alloy). Both copper and nickel are completely soluble in each other, which supports this very wide range of compositions. The most commonly produced cupronickel is the 90/10 (90% Cu, 10% Ni).In recent years, the price of both copper and nickel have steadily increased. The reason copper factors into the value of a nickel is because a standard Jefferson five-cent coin isn’t made from just nickel.
