Polished Tungsten Tube

Polished tungsten tube refers to semi-finished surface of pure tungsten tube after polishing products. Outer surface finish, wall caustic pure tungsten tube, the surface smooth, bright, shiny metal pan, the inner surface of the outer surface of the light is better. Pure tungsten tube diameter range is very wide, up to 100 mm, diameter size can also be controlled to 12 mm in length no restrictions, it can be customized according to user requirements. Usually taken pure tungsten tube through the use of pure tungsten rod system. Given its high temperature resistance, high melting point characteristics, pure tungsten tube can be used to protect its internal wire, the wire can also be introduced into the lumen to its high temperature gas or liquid.

Under standard conditions, unbound hard and rare metals, tungsten is a natural compound found on Earth. In 1781, a new element has been identified, first isolated in 1783 in the metal. Its important ores include wolframite and scheelite. Freedom notable feature is its excellent corrosion resistance, especially in the second highest of all the elements that most carbon it's all non-alloyed metal melting point later on. Equally striking is the high density of its 19.3 times that of water, comparable uranium and gold, much higher than the small amount of impurities of lead (approximately 1.7-fold), tungsten is often brittle and hard, making it difficult to work. However, very pure tungsten, though still difficult, more toughness, and can be cut with a hacksaw hard steel.
