COLSIBRO ®

Colsibro is a Copper Nickel Silicon alloy which offers a remarkable blend of properties. The combination of strength, corrosion resistance, high conductivity, wear resistance, spark resistance, cryogenic properties and numerous other attributes has enabled Colsibro to find a place in every engineering field from electrical to mechanical and automotive to marine.

Colsibro develops its unique performance by heat treatment and is stocked in its fully precipitation hardened, heat treated condition. The alloy is always fully stress relieved in the hardened condition which means that close machining tolerances can be held.

This is the preferred material for many “high performance” valve guide manufacturers
