Tungsten filament

Material:Tungsten
Size:0.3-0.8mm diameter.
Wire Quantity:2-4pcs
Application:Tungsten heater（Tungsten evaporation coil）is of many metal shapes and generally consists of one or several streams of doped tungsten wires. By special heat treatment technology, tungsten heaters have the features of high melting point, high corrosion resistance, good stability and long service life.

They are applied in fields as thin film technology, metal evaporation, mirror processing, and picture tube industry.
Tungsten filaments (W filaments; wolfram filaments) are always used in lighting industry like incandescent/halogen lights and standardized lamp coils for fluorescent lights. We can offer thousands of filament designs with respect to parameters such as basic coil type (single coil or several coils), bulb shape, gas fill, service life and lumen output.
Note: we supply them according to the drawing from the customers
