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.
