Tungsten Rod

Jan 07, 2019

Tungsten Rod 

has high melting point, high temperature strength and creep resistance, as well as good thermal conductivity, electrical conductivity and electronic emission properties. Low coefficient of expansion and minimum metal vapor pressure. 

Powder metallurgy is usually used to make it.


Tungsten electrodes are widely used in welding, high voltage anode, cathode discharge and heat conduction devices. Tungsten electrode can be used as probe needle, resistance welding electrode, plasma discharge electrode, fusion electrode and so on.
