5. Twisted wires for coating films under vacuum and for tungsten wires in electrical light sources usage.
Application:
1. Tungsten is widely used as refractory metals. In wire form, tungsten wire is essential for the production of lighting products and other goods where its high temperature properties are of use. Among its properties are a melting point of 3410C, a low coefficient of thermal expansion and low vapor pressure at elevated temperatures along with good electrical and thermal conductivity.
2. The important applications of tungsten wire are for the production of coiled incandescent lamp filaments, cathode and support structures for power tubes, heating elements for high temperature furnaces and evaporation sources in metallizing processes. Thicker sizes of tungsten wire, straightened, finish-ground and cut into rod pieces are widely used for glass-to-metal seal lead parts in the lighting and electronic industries.
3. tungsten filament is used as filament, cathode for emitting tube, high temperature electrodes
4. tungsten filament is mainly used as filament, cathode for emitting tube, high temperature electrodes, Tungsten wire in twisted, folded-heater for electronic tube, grid, gridsiderod for electron tube. The type contain WAL1, WAL2, WAL3, W1 , W2.
