Tungsten is the most widely used of the refractory metals. In wire form, it is essential for the production of lighting products such as wire filament, and other goods where its high temperature properties are of use. Among its properties are a melting point of 3410° C, a low coefficient of thermal expansion and low vapor pressure at elevated temperatures, along with good electrical and thermal conductivity.

Pure tungsten products are widely used for Furnace parts, Semiconductor Base Plates, Components for Electron Tubes, Emission Cathodes for Electron Beam Evaporation, Cathodes and Anodes for Ion Implantation, Tubes / Boats for Sintering of Capacitors, Targets for X-ray Diagnostics, Crucibles, Heating Elements, X-ray Radiation Shielding, Sputtering Targets and Electrodes.
