The Element Tungsten is defined as...
A hard, brittle, corrosion-resistant, gray to white metallic element extracted from wolframite, scheelite, and other minerals, having the highest melting point and lowest vapor pressure of any metal. Tungsten and its alloys are used in high-temperature structural materials; in electrical elements, notably lamp filaments; and in instruments requiring thermally compatible glass-to-metal seals.
Tungsten originates from the Swedish words 'tung sten' meaning heavy stone. It was formerly called Wolfram hence the symbol of the element "W". - Obtained from scheelite and wolframite.
Tungsten is also by far the most dense element you can buy for less than precious metal prices. It's exactly the same density as gold, but something like a hundred or more times cheaper. Lead is cheaper still, but tungsten is almost twice as dense, and in applications where size counts, tungsten is used. This includes counterweights in aircraft control surfaces, for example.
Common Uses of Tungsten
Space-age super-alloys
Light bulb filaments - fluorescent lighting
Cemented carbides (also called hardmetals)
Armaments
Jewelry - Tungsten Carbide
