Tungsten
Tungsten is a steel-gray, hard, brittle, crystalline metal, which is usually obtained in a form of a powder, the latter being made to assume the coherent metallic form by a process of hammering known as "swaging."
Added in small amounts to steel, tungsten hardens and toughens the metal. Tungsten is nowadays universally employed for making the filaments of electric lamps, as it is almost infusible and is thus able to withstand the prolonged heating to whiteness. In many of its properties, tungsten is allied to molybdenum and chromium.
Alloys of tungsten with aluminium, antimony, bismuth, cobalt, copper, lead and nickel have been obtained. Of all the known metals, tungsten has the highest melting point.
