Zirconium Tungsten Models and Features

Zirconia doped tungsten, zirconium tungsten electrodes produce. Specific data as follows:

Other grades dopant doping doping electron work function color coating head

WZ3 ZrO2 0.20 ~ 0.40% <0.20% 2.5 ~ 3.0 Brown
WZ8 ZrO2 0.70 ~ 0.90% <0.20% 2.5 ~ 3.0 White

Zirconium tungsten electrodes and pure tungsten electrodes, can only be of the AC welding work environment.

Zirconium tungsten electrodes in AC environment, good weldability. Especially in the case of high load currents, zirconium tungsten electrodes shown superior performance of the other electrode can not be replaced.

In welding, the end portion of the tungsten electrode of zirconium to maintain a reduced spherical tungsten infiltration phenomenon, and has good corrosion resistance.

Since the emergence of other alternative products, zirconium tungsten electrode demand will have a decreasing trend. Main alternative product is lanthanum tungsten electrode.
