The metal tungsten

Technical characteristics

Refractory heavy metal tungsten as the material is used in different industries. It can be used as an alloying element, heat-resistant steels and pure — filament lamps. Its main features are high melting temperature and a minimum temperature coefficient of linear expansion. Widely used in the metallurgical industry for alloying tool steel and armor alloys due to their refractory properties. Since the melting point of tungsten: 3387−3422°C, this metal was used to manufacture filaments in lamps and cathode ray tubes. This metal is the basis of a number of semi-finished products, such as:





Tungsten in a normal environment does not react with any chemical substances. Density it is identical to the gold — respectively: 19,30 g/cm3 against for 19.32 g/cm3.

Tungsten alloys

Stellite, wins and other tungsten alloys are characterized by high hardness. This quality was the main reason for their use in the manufacture of cutting tools. Such alloys have excellent resistance to wear, corrosion and cavitation resistance.

Tungsten is a rare element in the earth’s lithosphere. Under normal conditions it is very heavy, hard, not enough plastic. The difficulty of obtaining it in pure form, quite high processing because of the unique properties affect the final product cost.
