Important applications of cleaned 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 metalizing processes. Thicker wire 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. The
materials can be made filaments for auto lamps, fluorescent lamps, high
pressure halogen lamps and other lamp components.
