Tungsten wire has a wide variety of applications in a number of industrial application. In the Lighting Industry, Tungsten wire is essential for the production of lamp products such as wire filaments, where its high temperature properties are necessary. Among its properties are a melting point of 3410° C, a low coefficient of thermal expansion and low vapor pressure at elevated temperatures, as well as good electrical and thermal conductivity.
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 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.
