Tungsten and Molybdenum Wire in a variety of diameters is now available from stock and can be cut to your length, tolerance, concentricity, and straightness requirements.

Tungsten Wire

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.

stock Tungsten wire in a range of diameters from 0.001" to 0.125" and can be cut to your length, tolerance, concentricity, and straightness requirements. Typical uses include:

Medical Devices

Molybdenum Wire

Molybdenum wire is used in the construction of power tube grids and support structures which require high temperature strength, low vapor pressure and low thermal expansion. High temperature vacuum and hydrogen atmosphere furnaces also employ Molybdenum rod and Molybdenum wire to form resistance heating elements. Molybdenum wire is also used as a mount for Tungsten lamp filaments (which operate at temperatures in the range of 2400° C); the Molybdenum wire acts as both a heat sink and a support while lowering the temperature at the support junction.
