These Tungsten electrodes are manufactured by Plansee. It features a comprehensive melting point of all metals, a low vapor pressure, low thermal expansion, good thermal conductivity, and a low electron work function.
Anodes have to withstand extreme thermal loads. PLANSEE can supply special potassium-doped tungsten materials for this type of application: WVM and WVMW. These materials benefit from a high level of thermal stability, and are characterized by extensive arc erosion resistance.
