Chromium Zirconium Copper
Chromium-zirconium-copper (CuCrZr) chemical composition (mass fraction)% (Cr: 0.1-0.8, Zr: 0.3-0.6),hardness (HRB78-83),conductivity 43ms/m. Chromium-zirconium-copper has good electrical conductivity, thermal conductivity, high hardness, wear resistance, explosion resistance, crack resistance and high softening temperature. Its feature of low electrode loss during welding, fast welding speed, low total welding cost, then it is suitable for welding electrodes Related to pipe fittings, but general performance on electroplated workpieces is fair. This product is widely used in various materials for welding, conductive nozzles, switch contacts, mold blocks, and auxiliary welding devices in automobile, motorcycle, barrel (tank) and other machinery manufacturing industries.
Chemical composition：Cr0.5~1.5% Zr0.06-0.2% Cu Balance.
