The rare, silvery white element named tungsten (W) is a metal of superlatives. Its melting point is the highest of any pure metal. Its boiling point approaches surface temperatures of the sun. Its tensile strength is the highest of any metal under extreme temperatures. And its coefficient of thermal expansion is the lowest of any metal (meaning, it undergoes minimal expansion when heated).
Tungsten is similar to Molybdenum chemically and its chemistry is amongst the most complex of the transition elements. Tungsten is a relatively rare element, with a crystal abundance of around 1.0–1.5 mg kg-1, similar to that of its neighboring elements in the periodic table, Molybdenum.
Tungsten. Tungsten (W) is a gray-white metallic element that is stable and is very resistant to acids and bases. Tungsten has the highest melting temperature of any metal (3422 ° C or 6192 ° F), and the second highest of all elements (carbon is highest).

TUNGSTEN (REVISED) Note: This article, originally published in 1998, was updated in 2006 for the eBook edition. Overview Tungsten is a transition metal. The transition metals are a group of elements found in the middle of the periodic table .
The main mining area is China, which today accounts for more than two-thirds of the world's supply. Other places with active tungsten mines are Russia, Austria, Bolivia, Peru and Portugal. World production is around 40.000 tonnes per year and reserves are estimated to be around 5 million tonnes.
Tungsten carbide is an important compound in the metalworking, mining, and petroleum industries. Alloys such as high-speed steel, cristite, and stellite, used in high-speed tools, contain tungsten. Alloys such as high-speed steel, cristite, and stellite, used in high-speed tools, contain tungsten.
Tungsten Mining & Beneficiation. Tungsten is usually mined underground. Scheelite and/or wolframite are frequently located in narrow veins which are slightly inclined and often widen with the depth.
Tungsten mineral data, information about Tungsten, its properties and worldwide locations.
Tungsten carbide is immensely hard and is very important to the metal-working, mining and petroleum industries. It is made by mixing tungsten powder and carbon powder and heating to 2200°C. It makes excellent cutting and drilling tools, including a new 'painless' dental drill which spins at ultra-high speeds.
Tungsten is a material mainly used in creating tungsten plating, used in construction of the fission and fusion reactors. Tungsten is acquired through placing netherrack in a decomposer. As tungsten only has a 10% drop rate from netherrack, it is suggested you have plenty of it to meet the...
Tungsten's chemical symbol W comes from the German name Wolfram. Wolframite and scheelite are the two naturally occurring tungsten ores important for industrial use. In its raw form tungsten is a hard steel-grey metal that is often brittle and hard to work, pure tungsten metal is shiny white and quite pliant.

Tungsten (W) is a metal with a wide range of uses, the largest of which is as tungsten carbide in cemented carbides. Cemented carbides (also called hardmetals) are wear-resistant materials used by the metalworking, mining, and construction industries.
The chemical industry also consumes tungsten — tungsten compounds are used as lubricants, catalysts, pigments and enamels, as well as in electronics and for other electrical applications.
Tungsten occurs in the normal state hardly in the type of chemical compounds with supplementary elements. Even though more than 20 tungsten bearing minerals are identified, only 2 of them are important for industrial utilize specifically wolframite and scheelite.
Tungsten (W), also called wolfram, chemical element, an exceptionally strong refractory metal of Group 6 (VIb) of the periodic table, used in steels to increase hardness and strength and in lamp filaments.
