About 50% of tungsten is used in tungsten carbide, with the remaining major use being alloys and steels: less than 10% is used other compounds. [23] Tungsten is the only metal in the third transition series that is known to occur in biomolecules, being found in a few species of bacteria and archaea.

Its high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris. [24] Some of the applications of tungsten are not related to its refractory properties but simply to its density. For example, it is used in balance weights for planes and helicopters or for heads of golf clubs.
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 ...
The dominant use of sodium tungstate is as an intermediate in the extraction of tungsten from its ores, almost all of which are tungstates. [1] Otherwise sodium tungstate has only niche applications. In organic chemistry, sodium tungstate is used as catalyst for epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones. It ...
Tungsten has several oxidation states, and therefore oxides: Tungsten(III) oxide; Tungsten(IV) oxide, also known as tungsten dioxide; Tungsten(VI) oxide, also known as tungsten trioxide; Tungsten pentoxide
Copper–tungsten (tungsten–copper, CuW, or WCu) is a mixture of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite instead of a true alloy.
Tungsten(IV) oxide is the chemical compound with the formula W O 2. The bronze-colored solid crystallizes in a monoclinic cell. [1] The rutile-like structure features distorted octahedral WO 6 centers with alternate short W–W bonds (248 pm). [1] Each tungsten center has the d 2 configuration, which gives the material a high electrical ...
