tungsten electrode for resistance welding

Tungsten electrode has high melting point. It's good for high temperature strength, creep resistance, temperature electric and electron emission. Moreover, tungsten is low coefficient of expansion and the lowest metal vapor pressure. In generally, we adopt powder metallurgy to produce tungsten.

Tungsten electrode is used in welding, high voltage anode, cathode discharge and heat transfer devices.

HOSO Metal design the electrode especially for the resistance welding.

 tungsten electrode selection:

pure tungsten electrode≥99.95% tungstenhigh temperature resistance
tungsten cerium electrodes2% Cerium oxideA low electron work function, strong arcing ability, long service life
tungsten lanthanum electrode1-2% lanthanum oxidelow electron work function
tungsten thorium electrode2% thorium oxidegood thermal stability, radioactive
tungsten rhenium electrode5% or 26% rheniumcreep resistance capability
tungsten copper electrode10-60% copperhardness and electrical conductivity good balance

HOSO Metal can supply the finished tungsten parts according to customer's drawing
