Tungsten steel is any steel that has tungsten as its alloying element with characteristics derived mostly from the presence of this element (as opposed to any other element in the alloy). Common alloys have between 2% and 18% tungsten by weight along with small amounts of molybdenum and vanadium which together create an alloy with exceptional ...
Tungsten electrode used in a gas tungsten arc welding torch Tungsten filament is used in incandescent lightbulbs, where it is heated until it glows Because of its conductive properties and relative chemical inertness, tungsten is also used in electrodes , and in the emitter tips in electron-beam instruments that use field emission guns , such ...
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 ...

Electrical resistivity increases with an increase in the percentage of tungsten present in the composite, ranging from 3.16 at 55% tungsten to 6.1 when the composite contains 90% tungsten. An increase in tungsten leads to an increase in ultimate tensile strength up until the alloy reaches 80% tungsten and 20% copper with an ultimate tensile ...
During this period the company developed a new type of anti-tank projectile made of tungsten with a hard carbide core. [ 10 ] The company has expanded through acquisitions, [ 11 ] [ 12 ] including the purchase of Widia Group (2002, 188 million Euros) [ 13 ] Extrude Hone Corp. (2005, $137 million) [ 14 ] and Allegheny Technologies' tungsten ...
Tungsten ore is a rock from which the element tungsten can be economically extracted. The ore minerals of tungsten include wolframite, scheelite, and ferberite. Tungsten is used for making many alloys. Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions. [1]
