Tungsten wire can be used for producing electric light source parts and electric vacuum components, heating elements and refractory parts in high temperature furnaces and heating elements in vacuum metalizing or plating processes.
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.
