Tungsten

Tungsten (formerly wolfram) is a chemical element that has the symbol W and atomic number 74.

A very hard, heavy, steel-gray to white transition metal, tungsten is found in several ores including wolframite and scheelite and is remarkable for its robust physical properties.

The pure form is used mainly in electrical applications but its many compounds and alloys are widely used in many applications (most notably in light bulb filaments and in space-age superalloys)..
