Customized Special Shaped Electrode Pin Chrome Zirconium Copper

Customized special-shaped electrode pin spot welding machine against welding machine accessories chrome zirconium copper

Description:

Chromium-zirconium copper (CuCrZr) chemical composition (mass fraction) % (Cr:0.25-0.65, Zr:0.08-0.20) hardness (HRB78-83) electrical conductivity 43ms/m softening temperature 550°C Features: high strength and hardness , Electrical and thermal conductivity, good wear resistance and wear reduction, after aging treatment, the hardness, strength, electrical conductivity and thermal conductivity are all significantly improved, and it is easy to weld. Widely used in motor commutators, spot welders, seam welders, electrodes for butt welders, and other parts that require strength, hardness, conductivity, and pad conduction at high temperatures. The ideal mirror surface can be etched out by making EDM electrodes, and at the same time, the upright performance is good, and it can achieve the effect that pure red copper is difficult to achieve, such as thinning, and it performs well on difficult-to-machine materials such as tungsten steel. Chromium-zirconium copper has good electrical conductivity, thermal conductivity, high hardness, wear resistance and explosion resistance, crack resistance and high softening temperature, less electrode loss during welding, fast welding speed, and low total welding cost. It is suitable as an electrode for fusion welding machines About pipe fittings, but the performance of electroplated workpieces is average. Application: This product is widely used in various materials for welding, contact tip, switch contact, mold block, and welding machine auxiliary equipment in machinery manufacturing industries such as automobiles, motorcycles, and barrels (cans).

The electrode arm is a part that is easy to wear out in the resistance welding machine, and the working conditions of the electrode in the resistance welding are relatively harsh. In addition to good electrical and thermal conductivity, the materials used to make electrodes must also have good high temperature and high pressure resistance. At present, the common materials of resistance welding electrode arms are mainly copper and copper alloys. In the case of special welding occasions, high temperature resistant materials such as alumina or tungsten can also be used as the electrode arm. In resistance welding, the material of the electrode arm directly affects the welding quality, production cost and labor productivity.
