Colsibro: High-Strength Copper Nickel Silicon

Colsibro is a precipitation hardening copper nickel silicon that offers a remarkable blend of physical and mechanical attributes unrivalled by many other grades of copper alloy.

Its combination of high strength, corrosion resistance, high thermal and electrical conductivity, excellent wear resistance, spark resistance and good cryogenic properties has enabled Colsibro to find a place in virtually every engineering field, from electrical to mechanical and automotive to marine.

Colsibro is a high copper alloy with small additions of nickel and silicon, which combine to increase the strength, hardness and wear resistance of the material, while retaining many of the physical benefits of copper itself.
