Tungsten Particular Properties and Wide Applications

Tungsten is a kind of silvery metal with all the appearance comparable to steel. It has high melting point, low vapor stress and little vaporization velocity. Also, high hardness, outstanding high-temperature strength and house of electric conduction and thermal transfer are its physical properties. In normal temperature, Tungsten Chemical Properties are steady. It doesn?¡¥t react with air and water and is erosion resistant in order that it doesn?¡¥t resolve in hydrochloric acid, sulfuric acid, nitric acid and aqueous alkali, but only in mixture of chloroazotic acid, nitric acid and hydrofluoric acid. Nevertheless, in high temperature, it chemically combines with chlorine, bromine, iodine, nitrogen and sulfur but not hydrogen.

On account of specific properties of tungsten, it gets much favor by Tungsten Producers, taking the example of China Tungsten Online . At the same time, Tungsten Market place is considerably wide given that it has wide applications which cover mineral, metallurgy, machine, developing, transportation, electronic, chemical sector, light business, textile, military, aerospace, science and numerous industrial fields. Presently, tungsten is widely applied in modern day technology by the state of pure metal and alloy method. Alloy program major refers to alloy steel, cemented carbide determined by tungsten carbide, abrasion resistant alloy and great thermal alloy. Below, let?¡¥s come to its application in following industrial fields.

Cemented carbide based on tungsten carbide

Carbide of tungsten has high hardness, erosion resistance and infusibility as a result of Tungsten Metal Properties and mechanical properties of tungsten. It contains tungsten carbide and a tiny quantity of cobalt. Cobalt acts as metal of bonding agent to offer you alloy essential intensity. These tungsten carbide utilized in finished steel nevertheless include titanium, tantalum and niobic carbide. All these alloys are manufactured by energy metallurgic strategy. Cemented carbide cutter features a cutting speed far quicker than that of good chisel tool steel cutter. As a result, cemented carbide is mostly applied for cutting tools, mine tools and wire-drawing dies.

Great strength and abrasion resistant alloy

As the most infusible metal, tungsten would be the element of many high strength alloys such as alloys composed of tungsten, chromium, cobalt and carbon that are mostly utilized in surface coating on strongly erosion resistant parts like valve of aircraft engine, operating parts of die thermal cutter, impeller of turbine motor, digging gear and plowshare. In aviation, rocket technologies and other departments that have needs on high thermal strength on machine components, engine and some apparatus, tungsten and other fusible metal like alloy of tantalum, niobium, molybdenum and rhenium can be utilised as higher strength material.

Contact material and high proportion alloy

Tungsten-copper alloy and tungsten-silver alloy manufactured by powder metallurgy method has outstanding electrical conductivity and thermal conductivity of both copper and silver also as tungsten abrasion resistance. As a result, tungsten, by virtue of Tungsten Material Properties , becomes the powerful get in touch with material in manufacturing working parts like knife switch, disconnector and spot-welding electrode. As for those higher proportion alloys of tungsten, nickel and copper and alloys replacing copper with ion are utilized to manufacture gyroscope rotor, plane, balance weight of handle rudder, radioactive shield of radio isotope and charging basket.

Electric vacuum illuminating material

Tungsten is applied in electron tube production, radio electronics and X-ray technologies. Tungsten can be applied to create the anticathode and cathode of X-ray tube and gas discharge tube also as contactor of wireless apparatus and electrode of atom hydrogen welding gun. At meanwhile, tungsten would be the best material for glower and taenidium on account of Tungsten Filament Properties. Additionally, tungsten is applied to manufacture thermionic cathode and grid electrode of electronic oscillation tube, cathode of high pressure rectifier and separately heated cathode heater in various electronic instruments, which can operate in hydrogen, inert gases or vacuum.
