DIN 2.1293 Copper Chromium Zirconium Round Bars For Resistance Welding Electrodes
Description of Copper Chromium Zirconium:
Used extensively for cap style resistance welding electrodes.
Evidence suggests that it can provide less sticking and resist deformation longer than
its copper-chrome counterpart in some specific situations.
