The purity of lamp tungsten wireis at least 99.95% according to Chinese Standard. There are four grades of tungsten wire which include W1, W2, WAL2-2, WAL2-T.Lamp tungsten wireare widely used for production of filaments for lamps of coiled-coil or three-coiled incandescent lamp fluorescent lamp energy saving lamp halogen lamp household lamp decorative lamp automotive lamp special type lamp auto lamp and hi-color temperature lamps and so on
The important applications of black tungsten wires 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 metalizing processes. Thickerwire sizes, straightened, finish-ground and cut into rod pieces are widely used for glass-to-metal seal lead parts in the lighting and electronic industries.
White tungsten wiresare mainly applied for making various electron tubes, H series auto lamp, halogen lamp and other special lamps.
