Tungsten Properties

From a mining and metal industry perspective, tungsten falls into a loose grouping of around 20 metals termed “minor metals”.

Tungsten is unique in having a combination of relatively extreme properties compared to other metals; its properties include:

a very high melting point, 3,422°C (5,700°C, boiling) – highest melting point of all metals
a very dense, heavy metal, 19.25 g/cm3
an extremely strong, wear resistant metal; has a hardness close to that of diamonds – highest modulus of elasticity and highest tensile strength of all metals
thermally and chemically stable metal, with high thermal conductivity – lowest coefficient of expansion of the metals
a high electrical conductivity
a relatively inert metal which does not oxidise readily, is extremely corrosive resistant and relatively acid resistant and is deemed environmentally benign.
