Tungsten electrode is used in welding, high voltage anode, cathode discharge and heat transfer devices.Compare to the NDB and back casting technoloy to bulid the non-defect between the tungsten and copper shank, we use advanced CBT-technology bonding the shank with the No-ferrous metal tips. Zhuzhou Jielong's CBT no-ferrous insert spot welding electrode face material can be tungsten, Lanthanum tungsten, molybdenum, TZM, Silver tungsten.
