Contact material for vacuuminterrupter and method of making a contact material

摘要

Contact material for vacuum interrupter and method of making a contact material. In order to being enabled in a precise control of the Si concentration of Cu/Cr contact materials contact material has a chromium content which is above 10 wt.% and that the material is doped with silicon below 0 2 wt.% (2000 ppm Si) and the remainder is copper Cu.
