Tungsten definition

tŭngstən
A hard, gray to white metallic element that is very resistant to corrosion. It has the highest melting point of all elements, and it retains its strength at high temperatures. It is used to make light-bulb filaments and to increase the hardness and strength of steel. Atomic number 74; atomic weight 183.84; melting point 3,410°C; boiling point 5,900°C; specific gravity 19.3 (20°C); valence 2, 3, 4, 5, 6.

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 and wear-resistant tools and machine parts; in electrical elements, notably lamp filaments; and in instruments requiring thermally compatible glass-to-metal seals. Atomic number 74; atomic weight 183.84; melting point 3,422°C; boiling point 5,555°C; specific gravity 19.3 (20°C); valence 2, 3, 4, 5, 6.

Origin of tungsten

  • Swedish tung heavy (from Old Norse thungr) sten stone (from Old Norse steinn stāi- in Indo-European roots)

    From American Heritage Dictionary of the English Language, 5th Edition

  • From Swedish and Danish tung (“heavy") + sten (“stone") (although neither language uses "tungsten" as the name of the element)
