MET CuNi2SiCr - technical data sheet
Copper alloys: MET CuNi2SiCrAlternative designation: C18000 / CW111C / 2.0855 |
MET CuNi2SiCr is a thermally curable low-alloyed copper material with high stiffness, also at elevated temperatures. It offers good thermal and electrical conductivity combined with high corrosion resistance and is well suited for wear and sliding applications. The beryllium free copper alloy is used for tooling, as mold insert and for highly thermally stressed construction elements. |
