Tungsten, also known as wolfram, was first isolated in 1783 by charcoal reduction of the oxide (WO₃) derived from the mineral wolframite. Tungsten is a very hard, dense, silvery-white, lustrous metal that tarnishes in air, forming a protective oxide coating. Tungsten exists majorly in two forms; one of them is stable and has body-centered-cubic structure and the other is metastable. Among all the metals in pure form, tungsten has the highest tensile strength and melting point and when temperatures are above 1650°C, it has lowest vapor pressure. Also, it has lowest thermal expansion among all pure metals.

Tungsten is never found in nature in a free state, always combined with other elements. It is a rare element and the only minerals which are used industrially to obtain tungsten are either wolframite and scheelite.
