  Tungsten Metal (W) Element Chemical + Physical Properties

  The chemical symbol for tungsten is W which stands for Wolfram. The name came from medieval German smelters who found that tin ores containing tungsten had a much lower yield. It was said that the tungsten devoured the tin "like a wolf". Pure tungsten metal was first isolated by two Spanish chemists, the de Elhujar brothers in 1783.

  What is tungsten? ~ wolfram

  Tungsten is a metal as heavy as gold (density g /cm³), as hard as diamond (in the form of tungsten carbide) and so heatresistant, that iron is already boiling before tungsten melts (melting point: 3422 °C). The sheer variety of applications of the element with the symbol W is impressive.
