Pure tungsten is the material from which pure tungsten products are produced. Pure tungsten is so-called pure and its purity exceeds 99.95%. Products made from pure tungsten have the highest density of tungsten products, including tungsten alloys as well as carbide products. Pure tungsten products are preferred by customers for their high density, high temperature resistance, high corrosion resistance, high wear resistance, high hardness, and low thermal expansion.
Tungsten is a chemical element with the chemical symbol W and atomic number 74.
In standard conditions, hard and rare metals are not combined, and tungsten is a natural compound found on Earth. It was identified as a new element in 1781 and was first isolated from the metal in 1783. Its important ores include wolframite and scheelite. Remarkable for the free element is its excellent corrosion resistance, in particular the second highest record of all elements after carbon with the highest melting point of all non-alloyed metals. Also striking is its high density of 19.3 times water, comparable to uranium and gold, much higher than that of small amounts of impurities in lead. Tungsten (about 1.7 times) that tends to be brittle and hard, making it difficult to work with. However, very pure tungsten, although still difficult, is more ductile and can be cut with a hard steel hacksaw.
Unalloyed elemental forms are mainly used in electrical applications. Alloys of tungsten have many applications, the most notable being incandescent light bulb filaments, X-ray tubes (filaments and targets), and superalloys. The hardness and high density of tungsten give it penetrating power. The military tungsten compound for projectiles is the most commonly used industrial catalyst.
Tungsten is widely known as the transitional system between the third and fourth chemical elements in the biological age, and is a well-known heavy metal element in any organism. However, the breakdown of tungsten, molybdenum, and copper are all toxic to animals to some extent.
Pure tungsten products include tungsten electrodes, tungsten wires, tungsten contacts, tungsten heaters, tungsten wires, tungsten crucibles, etc.
