The name tungsten (which means ' heavy stone ' in Swedish and was the old Swedish name for the mineral scheelite and other minerals of similar density) is used in English, French, and many other languages as the name of the element, but wolfram (or volfram) is used in most European (especially Germanic and Slavic) languages and is derived from ...
Thirty-four artificial radioisotopes of tungsten have been characterized with mass numbers ranging from 156 to 194, the most stable of which are 181 W with a half-life of 121.2 days, 185 W with a half-life of 75.1 days, 188 W with a half-life of 69.4 days and 178 W with a half-life of 21.6 days.
Tungsten's high density and strength are also key properties for its use in weapon projectiles, for example as an alternative to depleted Uranium for tank gun rounds. [23] Its high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris. [24]

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...
