Product Details

Manufacturing process of tungsten filament:
Tungsten filament is the further product of tungsten wire. It also has the process of heating, forging and straightening into the thin filament.

Tungsten filament applications:
Tungsten filament is mainly used in the high color temperature bulb and shockproof lamp business. When the power level is sufficient to raise the temperature to above 1000f degrees Kelvin, visible light is pro
duced. Besides
tungsten filament bulb
, it is also used in scanning electron microscopy.

Properties of tungsten filament:
Tungsten filament is characterized by high melting point, low vapor pressure. In addition, it is quite sturdy and provides stable and uniform electron emission, therefore, tungsten filament is suited for manufacturing lamps. Its surface is smooth and has compact crystal structure.
