CuSn12Ni2

Bronze alloy

EN CC484K - UNS C90800

CuSn12Ni2 is a tin-nickel bronze alloy known for its excellent mechanical strength and high resistance to wear and fatigue. The addition of nickel improves corrosion resistance—particularly in marine environments—as well as the stability of its mechanical properties. This alloy is particularly well-suited for harsh environments that require durability and reliability.
