Tungsten Unique Properties and Wide Applications

Tungsten can be a type of silvery metal with the look similar to steel. It has higher melting point, low vapor pressure and tiny vaporization velocity. Also, high hardness, outstanding high-temperature strength and home of electric conduction and thermal transfer are its physical properties. In typical temperature, Tungsten Chemical Properties are stable. It doesn?¡¥t react with air and water and is erosion resistant so that it doesn?¡¥t solve in hydrochloric acid, sulfuric acid, nitric acid and aqueous alkali, but only in mixture of chloroazotic acid, nitric acid and hydrofluoric acid. However, in high temperature, it chemically combines with chlorine, bromine, iodine, nitrogen and sulfur but not hydrogen.

On account of special properties of tungsten, it gets significantly favor by Tungsten Producers, taking the example of China Tungsten On-line. Too, Tungsten Market is considerably wide given that it has wide applications which cover mineral, metallurgy, machine, constructing, transportation, electronic, chemical sector, light market, textile, military, aerospace, science and various industrial fields. Nowadays, tungsten is widely applied in modern day technologies by the state of pure metal and alloy program. Alloy program major refers to alloy steel, cemented carbide according to tungsten carbide, abrasion resistant alloy and fantastic thermal alloy. Under, let?¡¥s come to its application in following industrial fields.

Cemented carbide depending on tungsten carbide

Carbide of tungsten has higher hardness, erosion resistance and infusibility due to Tungsten Metal Properties and mechanical properties of tungsten. It contains tungsten carbide and a little quantity of cobalt. Cobalt acts as metal of bonding agent to supply alloy required intensity. Those tungsten carbide utilized in finished steel nonetheless contain titanium, tantalum and niobic carbide. All these alloys are manufactured by energy metallurgic technique. Cemented carbide cutter features a cutting speed far faster than that of excellent chisel tool steel cutter. Consequently, cemented carbide is mainly applied for cutting tools, mine tools and wire-drawing dies.

Wonderful strength and abrasion resistant alloy

Because the most infusible metal, tungsten would be the element of numerous higher strength alloys like alloys composed of tungsten, chromium, cobalt and carbon which are primarily employed in surface coating on strongly erosion resistant parts like valve of aircraft engine, operating parts of die thermal cutter, impeller of turbine motor, digging equipment and plowshare. In aviation, rocket technology along with other departments that have requirements on higher thermal strength on machine components, engine and some apparatus, tungsten as well as other fusible metal like alloy of tantalum, niobium, molybdenum and rhenium could be utilised as high strength material.

Get in touch with material and higher proportion alloy

Tungsten-copper alloy and tungsten-silver alloy manufactured by powder metallurgy technique has superb electrical conductivity and thermal conductivity of both copper and silver as well as tungsten abrasion resistance. Thus, tungsten, by virtue of Tungsten Material Properties , becomes the successful make contact with material in manufacturing operating components like knife switch, disconnector and spot-welding electrode. As for all 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 technology. Tungsten might 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 may be the best material for glower and taenidium on account of Tungsten Filament Properties. Furthermore, tungsten is applied to manufacture thermionic cathode and grid electrode of electronic oscillation tube, cathode of higher pressure rectifier and separately heated cathode heater in a variety of electronic instruments, which can operate in hydrogen, inert gases or vacuum.
