Tungsten is a wonderful strong metal of nature!

It is a rare metal that occurs naturally on Earth almost exclusively as compounds with other elements. Tungsten, known as a heavy engineering metal, has a density of 19.35 g/cm3 at 20°C.

 Its tensile strength is 1 lakh 42 thousand psi. Moreover, its melting point is 3,695 Kelvin and boiling point is 5,555 degrees Celsius. Tungsten forms chemical compounds in oxidation states -II to VI. 

 Tungsten was identified as a distinct element in 1781 and first isolated as a metal in 1783. As a rare metal, tungsten is not found in nature as a pure element, but as an ore compound. 

 This rare and extremely heavy tungsten metal is mainly used in rifle bullets, surgical components, light bulb filaments and heating devices. Moreover, it is used in integrated circuits as an interconnecting component of electronic devices. 

 Tungsten metal is used to make alloys for aircraft engine turbine blades, rocket-engine nozzles, and darts.
