Tungsten metal is the only metal that is known to occur in the double molecule, where it is used in the third transition series of several species of bacteria. It is known to be the heaviest metal for any living organism. However, tungsten interferes with the metabolism of molybdenum and copper and is toxic to animal life.
Because tungsten retains its high temperature strength and has a high melting point, the most dense metal tungsten is used in many high-temperature applications such as light bulbs, cathode ray tubes, and vacuum tubes, heating elements, and rocket engine nozzles. Its high melting point also makes tungsten suitable for aerospace and high-temperature use such as electric, heating and welding applications, especially in tungsten argon arc welding (also known as tungsten inert gas (TIG) welding).
Armament, Tungsten Metals alloys with nickel and iron or cobalt form heavy alloy tungsten metals, using kinetic energy-piercing armor as an alternative to depleted uranium, Tungsten Metals in applications that do not require additional predictive properties of uranium (for example, in ordinary small-arms bullets designed to penetrate bulletproof vests). Similarly, tungsten alloys are also used in cannon shells, grenades and missiles to build supersonic shrapnel.
Tungsten is similar in density to gold, allowing the use of tungsten in jewelry as an alternative to gold or platinum. This feature has been used to create a thin layer of gold bullion made from tungsten on the surface. Its hardness makes it an ideal ring that will resist scratching, Tungsten Metals is hypoallergenic and will not require polishing, which is particularly useful in the design of abrasive treatment.
Use of tungsten metals
Tungsten metal applications include heat sinks, weights, counterweight, ballast keel yachts, tail ballasts for commercial aircraft and ballast racing for NASCAR and formula I. It is an ideal material to be used as a car's riveting, and in the necessary quality good effect can be achieved in a compact bar. The density of nickel, copper, or iron tungsten is used as a high quality dart (allowing a smaller diameter, thus a tighter grouping) or bait (tungsten beads allow the fly to sink rapidly). Tungsten Metals Some types of instrument strings are rolled around with tungsten wires.
Tungsten metals are used as catalysts, inorganic pigments (such as tungsten oxide) and as high-temperature lubricants (tungsten disulfide). Tungsten carbide (WC) is used for the manufacture of wear-resistant abrasives and knives and tools for drill bits, circular saws, milling cutters and used metal processing, wood processing, mining, petroleum, construction and other industry knives, accounting for about 60% of the current consumption of tungsten. Tungsten oxides are used in ceramic glazes and calcium/magnesium. Tungsten Metals Tungsten metals are widely used in fluorescent lighting, halogen-tungsten bulbs, often used to illuminate indoor photo shoots, and special negatives exist in order to take advantage of the unique characteristics of tungsten. Crystal East states as scintillation detectors in nuclear physics and medicine. Other salts containing tungsten are used in the chemical and tanning industries.
Tungsten metals are electrically conductive and relatively chemically inert, and tungsten is also used on electrodes and in the use of field emission guns, such as electron microscope electron beam apparatus of the emitter. In electronics, tungsten metals are used as interconnect materials in integrated circuits, Tungsten Metals between dielectric materials and transistors of silicon dioxide. This is used in the metal film, which replaces the wiring used in traditional electronics with tungsten (or molybdenum) on the coating of silicon.
The electronic structure of tungsten makes it a major source of X-ray targets and is also shielded from high-energy radiation (for example, in the radioactive drug industry, for shielding FDG radioactive samples). Tungsten powder as filler material in plastic composites, it is used as a non-toxic alternative to lead-fired bullets and radiation shielding. Because of the thermal expansion of these metals similar to borosilicate glass, Tungsten Metals it is used to make glass-metal seals.
The density of tungsten is applied to the acquisition of heavy metal alloys. A good example is the high-speed steel, which may contain up to 18% tungsten. Tungsten has a high melting point, making good tungsten materials like the application of rocket nozzles, such as the UGM-27 Polaris submarine-launched ballistic missile. Tungsten-containing high-temperature alloys, such as nickel-based alloys and tungsten-chromium-cobalt alloys, are used in turbine blades and wear-resistant parts and paints.
