CuNi2Si (CW111C) is a copper-nickel silicon alloy that offers unique chemical and mechanical characteristics. CuNi2Si is a superior product compared to other copper alloy grades; the material promotes many beneficial performance qualities that virtually any engineering or fabrication company can benefit from. The material's corrosion resistance is excellent and surpasses the performance of the majority of copper alloys while also being free from the effects of stress corrosion and hydrogen embrittlement.
Other Qualities
Wear and bearing characteristics are also superior, and the material benefits from high strength and hardness. When compared to non-ferrous alloys, the thermal and electrical conductivity of CuNi2Si is excellent. This alloy provides exceptionally low magnetic permeability, outstanding performance in cryogenic environments and spark resistance.
Key Applications
CuNi2Si copper bars find typical use in cryogenic storage tanks, electrical components and engine valve guides & seats.
