Chromium copper is the primary copper alloy used for resistance spot and seam welding. This alloy achieves good hardness and electrical conductivity though a combination of heat - treatment and cold work. C18200 is utilized for electrodes, holders, adaptors, as well as numerous electrical applications where resistance to deformation at high temperature is required or when higher mechanical properties than C11000 are required.
