Tungsten, also called Wolfram, is a steel-gray colored metal found in nature. The name Tungsten comes from the swedish language where "tung" means heavy and "sten" means rock. 

Tungsten is most famous for it's physical properties. It has the highest melting point of all metals and high strength at high temperatures.

Tungsten is often used for it's good conductivity for heat and electricity as well as for it's high absorbation capacity for radioactive radiation and X-rays.

Tungsten is found principally in one of two forms viz combined with iron and manganese oxides, which is called wolframite WO₄ or combined with calcium as calcium tungstate which is called scheelite, CaWO₄, the later being the most common. The tungsten compounds seldom exeed 2 % of the orebody.
