 The different color's tungsten electrodes

   TIG Tungsten electrodes come in various types with different purposes for each.Every tungsten electrode has its color,today SHAANXI YUHENG introduces different color's tungsten electrodes.

  White tungsten electrodes are 0.8% Zirconiated and have been specifically designed for welding aluminium in AC.White tips are referred to as WZr08.

  Black, Gold and Blue tungsten electrodes are 1%, 1.5% and 2% Lanthanated, respectively. Lanthanated rods are mainly used for high-alloyed steel, titanium, nickel, copper and magnesium. The higher the percentage the better the ignition characteristics. The life of the tungsten is less than the purple tips. Lanthanated tips are referred to as WLa10, WLa15 and WLa20.

  Red tungsten electrodes are 2% Thoriated and designed for use with mild steel and stainless steel however because of the radioactive element they are slowly being phased out in favour of the E3 purple tips.Red tips are referred to as WTh20.

  Green tungsten electrodes are pure tungsten and is mostly a hang over from America where they use this electrode for aluminium welding - the life of this tungsten is less compared to white.
