Tungsten Filaments


What is Tungsten Fliaments?

Tungsten Filament is arguably the key component of the incandescent lamp business.

tungsten filamentsThe tungsten filament of a vacuum incandescent lamp is heated to temperatures where visible light is emitted by resistance heating. The tungsten filament acts as an electrical resistor, which dissipates power proportional to the voltage applied, times the current through the tungsten filament. When that power level is sufficient to raise the temperature to above 1000 degrees Kelvin, visible light is produced.

The Tungsten Filament is quite sturdy and provides stable and uniform electron emission, primarily used in scanning electron microscopy. Custom

tungsten filament cathodes in a variety of tungsten filament sizes and configurations and a variety of glass or ceramic bases are available. Some combinations of various options may not be possible due to design considerations. All tungsten cathodes are shipped pre-fired, vacuum clean, and ready to install.

Application of Tungsten Filament:

1.Tungsten heater element and other heater components in semiconductor.

2.High temperature lamp filament, stock-resistance filament, double helix filament, etc.

3.Electric incandescent lamp filament, fluorescent light filament, etc.
