tungsten bar rod

is similar to tungsten rod. It adds straightening and other further processed to get thin tungsten rod.

Tungsten bar applications:
Tungsten rod is used to stretch for making tungsten wire and other shape of products. Besides, it is widely adopted to electrical system, voltage regulator in automobile engine and making electrode, electronic tube, cylinder barrel of advanced automobile and etc.

Properties of tungsten rod:
Our Tungsten bar features hardness, low mechanical abrasion with smooth surface. Moreover, It characterized by high temperature resistance and high creep resistance.
