The Materials You Need When You Need Them

Tungsten

Many practical applications of Tungsten are based on its high melting point and density and its low vapor pressure. Tungsten is an excellent material for high vacuum technology, dimensional stability, glass seals and furnace construction. In addition, Tungsten’s high density gives it a capacity to absorb radioactive radiation. Tungsten has found wide use as additives to steel to enhance physical properties and an alloy with nickel, copper and iron to provide high density machinable materials.

Applications - Precision/Cut Wire

Tungsten wire has a wide variety of uses in a number of industrial applications, including lighting, radiation shielding, medical devices, support structures for power tubes, vacuum heating, evaporation sources in metallizing processes, office machinery, and others. Among the properties of Tungsten are its high melting point of 6170° F (3410° C), a low coefficient of thermal expansion and low vapor pressure at elevated temperatures, along with good electrical and thermal conductivity.
