Tungsten electrode has high melting point. It has excellent proporites for high temperature strength, creep resistance, electron emission. Moreover, tungsten is low coefficient of expansion and the lowest metal vapor pressure. In generally, we adopt powder metallurgy to produce tungsten alloy.
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.
