  • Pure Tungsten , the least expensive of all tungsten electrodes, is generally used in the AC welding of aluminum and magnesium alloys
  • Yttriated Tungsten is primarily used in military and aviation industry with narrow arc beam,high compressing strength,highest welding penetration at medium and high current.
  • The performances of Composite Electrodes in welding can be much improved by adding two or more rare earth oxides which are mutually completementary.
