Binary Composite Tungsten Electrodes

In the binary composite tungsten electrodes, W-La-Ce electrode has lower arc voltage and at low current conditions, it has good arc stability. W-Y-Ce electrode composite electrode has best arcing and anti-burning properties. Besides, it has good arc stability and has large thermal power. W-La-Y has similar arc performance with W-La-Ce electrode and W-Y-Ce electrode, but it has large thermal power is larger, so large current anti-burning properties is lower than W-La-Ce electrode and W-Y-Ce electrode.
