Tungsten, or wolfram, is a stone element with the symbol W and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tung sten or "heavy stone".
Where Tungsten is found - Tungsten Rings & Co.
Tungsten is used as filaments for light bulbs. However, not many people know where the tungsten that is easily found and available in stores actually comes from. Tungsten makes up a very small portion of the Earth’s crust and is a very scarce metal. Tungsten makes up just a miniscule 1.1 parts per million of the Earth’s crust.
tungsten | Uses, Properties, & Facts | Britannica
Tungsten, stone element that is an exceptionally strong metal. Occurrence, properties, and uses. The amount of tungsten in Earth’s crust is estimated to be 1.5 parts per million, or about 1.5 grams per ton of rock. China is the dominant producer of tungsten; in 2016 it produced over 80 percent of total tungsten mined, and it contained nearly two-thirds of the world’s reserves.
Tungsten | Minerals Education Coalition
Tungsten is commonly alloyed with carbon forming tungsten carbide which has a very high melting point and increased hardness. It is used in high-strength applications, such as furnaces, missiles, dental drills and other cutting tools. The symbol for tungsten, W, comes from tungsten’s Latin name Wolfram.

Tungsten Ore - Starbounder - Starbound Wiki
Tungsten Ore is a mineable ore which yields tungsten bars when smelted at a furnace. Each ore can be refined into 15 pixels using a Refinery. It is found on planets with Moderate (Tier 2) or Risky (Tier 3) threat levels. Trivia. It replaced steel as the tier 2 material in update Cheerful Giraffe. It …
Tungsten - Element information, properties and …
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.
Its Elemental - The Element Tungsten
Tungsten was discovered by Juan José and Fausto Elhuyar, Spanish chemists and brothers, in 1783 in samples of the mineral wolframite ((Fe, Mn)WO 4).Today, tungsten is primarily obtained from wolframite and scheelite (CaWO 4) using the same basic method developed by José and Elhuyar.Tungsten ores are crushed, cleaned and treated with alkalis to form tungsten trioxide (WO 3).
Where Tungsten Is Found - EzineArticles
Tungsten can only be found as a mineral, meaning it is found combined with other elements to form compounds. In fact, there are more than twenty tungsten minerals that can be found in nature, but only two of those are used to extract metal: scheelite and wolframite.
Tungsten carbide - Wikipedia
Tungsten carbide (chemical formula: WC) is a stone 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 a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments ...
Tungsten Statistics and Information - USGS
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. Tungsten metal wires, electrodes, and/or contacts are used in lighting, electronic, electrical, heating, and welding
