Preparation and Performance of Cu-Cr Contact Materials for Vacuum Switches with Low Contact Pressure

Insufficient anti-welding properties limit the application of Cu-Cr contact material in vacuum switches with low contact pressure. The CuCr-W-C alloys that are prepared are for decreasing welding tendencies and keeping the voltage withstand by addition of W and C elements. It is found that the avera...
