CuNi2SiCr


CuNi2SiCr is a thermal curable copper alloy. Typical for CuNi2SiCr is a favorable combination of electrical and thermal conductivity accompanied by high stiffness, also at elevated temperatures. This copper alloy features a high corrosion resistance and is very well suited for wear and sliding applications. Furthermore, CuNi2SiCr fulfills the requirements of a conductive contact material in electrical engineering and for electrodes in welding.
CuNi2SiCr is used for tooling because of its strong hardness and its high level of wear resistance. Furthermore, CuNi2SiCr-alloy is very well suited for highly thermally-stressed construction elements and for the use of a beryllium-free copper alloy.
