Technological properties

Property
Application areas

It is used as a material for welding electrodes. Tungsten is doped with two percent cerium oxide by weight to obtain a material with a lower electron work function, better ignition characteristics and a longer service life than pure tungsten.

Other

Suitable as a substitute for WT20.
