A nickel, sometimes mistakenly called a nickle, is a five- cent coin struck by the United States Mint. Composed of cupronickel (75% copper and 25% nickel ), the piece has been issued since 1866. Its diameter is 0.835 inches (21.21 mm) and its thickness is 0.077 inches (1.95 mm). 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).
