Tungsten occurs in many alloys, which have numerous applications, including incandescent light bulb filaments, X-ray tubes, electrodes in gas tungsten arc welding, superalloys, and radiation shielding. Tungsten's hardness and high density make it suitable for military applications in penetrating projectiles.
Tungsten was discovered in 1781 by Swedish chemist Carl Wilhelm Scheele. Tungsten has the highest melting point of all metals, at 3,410 °C (6,170 °F). Filament of a 200 watt incandescent lightbulb highly magnified. Up to 22% Rhenium is alloyed with tungsten to improve its high temperature strength and corrosion resistance.
Tungsten disulfide is the first material which was found to form non-carbon nanotubes, in 1992. [6] This ability is related to the layered structure of WS 2 , and macroscopic amounts of WS 2 have been produced by the methods mentioned above. [ 13 ]
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.
rWNiCo: tungsten (91–93%), nickel (3–5%) and cobalt (2–4%) rWNiFe: tungsten (91–93%), nickel (3–5%) and iron (2–4%) Upon detonation of the explosive, the casing disintegrates into extremely small particles, as opposed to larger pieces of shrapnel which results from the fragmentation of a metal shell casing. The HMTA powder acts like ...
