including tungsten and carbide products

Pure tungsten is the production of pure tungsten products, materials. Pure tungsten is called its purity more than 99.95% pure. Products made of pure tungsten has the highest density of tungsten products, including tungsten and carbide products. Pure tungsten products are preferred by the customer, its high density, high temperature, high corrosion resistance, high wear resistance, high hardness, and low thermal expansion.
Tungsten wire is a chemical element, chemical symbol W and atomic number 74.

In the standard case, the hard and unbound metals, tungsten is a natural compound found on Earth. In 1781 was identified as a new element, first isolated in 1783 out of the metal. The important ores including wolframite and scheelite. Freedom is a significant element of its excellent corrosion resistance, especially that it's all non-alloyed metals highest melting point of all the elements after carbon second highest on record. Equally striking is its high density of 19.3 times that of water, comparable to uranium and gold, a small amount of impurities higher than lead.Tungsten (approximately 1.7 times) that tend to be brittle, hard, making it difficult to work. However, very pure tungsten, though still difficult, more resilient, and can be cut with a hard steel hacksaw.

Elements in the form of non-alloy is mainly used in electrical applications. Tungsten alloy has many applications, most notably incandescent bulb filaments, X-ray tube (filament and target), and high-temperature alloys. Hardness and high density tungsten penetration of the projectile to give it a military tungsten compounds are the most commonly used industrial catalysts.

Tungsten been widely known in the chemical elements of biological age living in the third and fourth lines of the transition, in any organism, are well-known heavy metal elements. However, to the extent of tungsten, molybdenum, copper are toxic to animals decomposition. (From Wikipedia)
