Tungsten Copper Nozzle

Tungsten copper nozzle has a long service life, which is several times of common copper material, and it greatly reduces the cost of production. Because of the relatively high conductivity, the high temperature by welding is quickly transferred; the core hardness and wear resistance of the conductive nozzle are continuously strengthened. Its coaxiality and finish are very high in order to meet the strict requirements of the military field. The nozzle usually mounted at the end of the welding equipment to guide the welding wire, the weld quality is high, less smoke and no arc.

Because of the use of electric current and the electric field intensity is high, the conductive nozzle material which is used in the field of military high not only been needed for good conductive and thermal conductivity, the hardness, strength and electric resistance of ablation need to be improved. Compared with the copper and chromium zirconium copper electrode, in spite of the high current environment, tungsten copper nozzle can also keep a good performance; the arc ablation resistance is strong to increase the service life. Compared with the copper and CuCrZr nozzle, it is easy to occur adhesion during welding, bonding wire and conductive nozzle, spatter plug the nozzle which leads to the failure of conductive nozzle.
