tungsten bar are extensively used in manufacturing industry and other industries

Manufacturing process of tungsten wire:

Tungsten wire   

comes out through the process of heating, forging of tungsten rod, and then straightened for several times.
 
Tungsten wire applications:
Tungsten wire is universally used to make 

tungsten wire resistance

 for bulb, lamps. Besides, it can be used in making optical instrument, electric vacuum components, high temperature resistant parts.

Properties of tungsten wire:
 Tungsten wire is characterized by highest melting point, excellent electric conductivity. It has high performance in sintering and high temperature in recrystallization. For the above features, it can serve a long life in any applications.

Tungsten wire dimensional tolerances lengths:
