· Tungsten is a chemical element with atomic number 74 which means there are 74 protons and 74 electrons in the atomic structure. The chemical symbol for Tungsten is W. Tungsten is a rare metal found naturally on Earth almost exclusively in chemical compounds. Tungsten is an intrinsically brittle and hard material, making it difficult to work.
Tungsten is a naturally occurring element. It occurs in rocks and minerals combined with other chemicals, but never as a pure metal. Elemental tungsten is a white to steel gray metal (depending on the purity) that can be used in pure form or mixed with other metals to make alloys. Tungsten alloys tend to be strong and flexible, resist wear, and conduct electricity well.
· Tungsten (atomic number 74, element symbol W) is a steel-gray to silver-white metal, familiar to many people as the metal used in incandescent light bulb filaments.Its element symbol W derives from an old name for the element, wolfram. Here are …
Tungsten Heating Element (Tungsten heater) is made from tungsten wire or other pure tungsten products, which has high melting point and excellent corrosion resistance. It is mainly used as heating elements in surface vacuum coating process such as aluminum spraying, chrome-plated, mirror making, ceramic coating and plastics coating, etc.
· Tungsten is a metallic chemical element classified among the transition metals of the periodic table of elements. It is well known for its strength and durability, which make it extremely useful in a wide range of industrial applications. Some consumers also own products which contain tungsten or were produced with the metal.
tungsten is a metal element with the element symbol W. It has high hardness, high melting point, and is not corroded by air at room temperature; it is mainly used to manufacture filaments, high-speed cutting alloy steels, super-hard molds, and also used in …
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. Tungsten metal was first isolated (1783) by the Spanish chemists and mineralogists Juan José and Fausto Elhuyar by charcoal reduction of the oxide (WO3) derived from the …
· It is correct that if the name wolfram is not used in nomenclature, students will have to learn some history of chemistry to know why the element symbol is W. Tungsten shares this, of course, with a number of other elements, such as potassium, mercury, and

· Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor …
· Tungsten is a metallic transition element in Period 6, Group 6 of the Periodic Table. It was first described in 1783 by Spanish brothers Juan Jose and Fausto de Elhuyar. They named the element Wolfram after a term used by the ancient tin miners in Saxony-Bohemia, describing a still unknown mineral.
Tungsten occurs in wolframite, scheelite, huebnertie, and ferberite. Important deposits of tungsten occur in California, Colorado, South Korea, Bolivia, Russia, and Portugal. China is reported to have about 75% of the world's tungsten resources. Natural tungsten contains five stable isotopes. Twenty one other unstable isotopes are recognized.
· Tungsten Heater Elements What is heating element. Heating element is an electrical device which converts electricity into heat.Heating elements are used in things like heaters,dish washers, stoves, hair dryers, ovens, coffee makers, toasters, and all sorts of other devices which generate heat to function.. Heating elements consist of coils of wire, which may be wrapped in …

· Tungsten (Swedish tung sten meaning "heavy stone"), even though the current name for the element in Swedish is wolfram (sometimes spelled in Swedish as volfram), from the denomination volf rahm by Wallerius in 1747, translated from the description by Agricola in 1546 as Lupi spuma, meaning "wolf's froth" after the way tin is eaten up like a ...
· Tungsten is used for electric contacts, arc-welding electrodes and for heating elements in high temperature furnaces. High-speed steels contain around 7% tungsten and these are used for saw blades, punches, dies and other high impact devices. However, so-called cemented carbide tools are taking their place. Tungsten carbide
· Tungsten or Wolfram. Tungsten; also known as wolfram; It is a chemical element with the chemical symbol W. Tungsten is only found on Earth combined with other chemical compounds. The pure element has strong physical characteristics; Especially the FET that has the highest spindle point of all the metals without alloy and the second highest of ...
