Manufacturing process of tungsten bar:
We are strict in the process of manufacturing

tungsten bar

. In order to offer better quality

pure tungsten

, we imported advance production equipments including IF induction sintering furnace, forging machine, wire cutting machine and others. The specific process including leather sheath modeling, sintering, forging, annealing, mechanical processing and further processes.
 
Tungsten bar applications:
Tungsten bar is used to make tungsten wire. Besides, it is widely applied in high temperature furnace, vacuum furnace, and sapphire crystal furnace. We can offer pure tungsten with purity of 99.95%.
 
Properties of tungsten bar:
Tungsten bar features high temperature resistance and high creep resistance. In addition, it has good high-temperature strength and electrochemical corrosion resistance.
