China Best Chromium Copper Alloy Bar for Spot Welder

Chromium zirconium copper has good conductivity, thermal conductivity, high hardness, wear resistance, explosion resistance, crack resistance and high softening temperature. It has less electrode loss during welding, fast welding speed and low total welding cost. It is suitable to be used as the electrode related pipe fittings of the welding machine, but it is generally used for electroplating workpieces.

At room temperature and higher temperature (400 ° С) It has high strength and hardness, good electrical conductivity and thermal conductivity, good wear resistance and antifriction. After age hardening treatment, the strength, hardness, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld and braze. It has good corrosion resistance in atmosphere and fresh water, good high-temperature oxidation resistance, and can withstand pressure processing in cold and hot states, but its disadvantage is that it is sensitive to notch, Stress concentration at notch and sharp corner is easy to cause mechanical damage. Therefore, it is not suitable to make commutator slices.
