Tungsten is a chemical element with the symbol W and the atomic number 74. It is a grayish-white lustrous metal. Pure Tungsten is mainly used in electrical applications while Tungsten alloys are used in various applications, especially in incandescent lights as filaments, in X-ray tubes (as both the filaments and targets) and in super alloys.

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. Also, tungsten is widely used as an alloy with nickel, copper and silver to provide high density machinable materials.
