tung·sten

 (tŭng′stən)
n. Symbol W
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. Also called wolfram. See Periodic Table.

[Swedish : tung, heavy (from Old Norse thungr) + sten, stone (from Old Norse steinn; see stāi- in Indo-European roots).]

tungsten

(ˈtʌŋstən)
n
(Elements & Compounds) a hard malleable ductile greyish-white element. It occurs principally in wolframite and scheelite and is used in lamp filaments, electrical contact points, X-ray targets, and, alloyed with steel, in high-speed cutting tools. Symbol: W; atomic no: 74; atomic wt: 183.85; valency: 2–6; relative density: 19.3; melting pt: 3422±20°C; boiling pt: 5555°C. Also called: wolfram
[C18: from Swedish tung heavy + sten stone]

tung·sten

(tŭng′stən)
Symbol W A hard, gray to white metallic element that is very resistant to corrosion. It has the highest melting point of all elements. Tungsten remains very strong at high temperatures and is used to make light-bulb filaments and to increase the hardness and strength of steel. Atomic number 74. Also called wolfram. See Periodic Table.
