Tungsten is actually a variety of
silvery metal together with the appearance equivalent to steel. It has high
melting point, low vapor stress and tiny vaporization velocity. Also, higher
hardness, exceptional high-temperature strength and property of electric
conduction and thermal transfer are its physical properties. In normal
temperature, Tungsten Chemical Properties are stable. It
doesn?¡¥t react with air and water and is erosion resistant so 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. However, in higher 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 . As well, Tungsten Market place
is considerably wide given that it has wide applications which cover mineral,
metallurgy, machine, building, transportation, electronic, chemical industry,
light business, textile, military, aerospace, science and a variety of
industrial fields. Presently, tungsten is extensively applied in modern
technology by the state of pure metal and alloy system. Alloy system primary
refers to alloy steel, cemented carbide according to tungsten carbide, abrasion
resistant alloy and excellent thermal alloy. Below, let?¡¥s come to its
application in following industrial fields.
Cemented carbide according to
tungsten carbide
Carbide of tungsten has higher
hardness, erosion resistance and infusibility as a result of Tungsten Metal Properties and mechanical
properties of tungsten. It contains tungsten carbide as well as a small
quantity of cobalt. Cobalt acts as metal of bonding agent to offer alloy needed
intensity. These tungsten carbide utilized in finished steel nonetheless
include titanium, tantalum and niobic carbide. All these alloys are
manufactured by power metallurgic method. Cemented carbide cutter includes a
cutting speed far quicker than that of excellent chisel tool steel cutter.
Consequently, cemented carbide is mostly applied for cutting tools, mine tools
and wire-drawing dies.
Wonderful strength and abrasion
resistant alloy
As the most infusible metal,
tungsten may be the element of a lot of higher strength alloys like alloys
composed of tungsten, chromium, cobalt and carbon that are mostly used in
surface coating on strongly erosion resistant parts like valve of aircraft
engine, working components of die thermal cutter, impeller of turbine motor,
digging equipment and plowshare. In aviation, rocket technology and other
departments that have requirements on high thermal strength on machine
components, engine and some apparatus, tungsten and also other fusible metal
like alloy of tantalum, niobium, molybdenum and rhenium can be utilized as
higher strength material.
Speak to material and high
proportion alloy
Tungsten-copper alloy and
tungsten-silver alloy manufactured by powder metallurgy technique has
exceptional electrical conductivity and thermal conductivity of both copper and
silver too as tungsten abrasion resistance. As a result, tungsten, by virtue of
Tungsten Material Properties , becomes the efficient speak to
material in manufacturing working components like knife switch, disconnector
and spot-welding electrode. As for those high proportion alloys of tungsten,
nickel and copper and alloys replacing copper with ion are employed to
manufacture gyroscope rotor, plane, balance weight of control 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 generate the anticathode and cathode of X-ray tube and gas discharge
tube at the same time 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. Moreover, tungsten is
applied to manufacture thermionic cathode and grid electrode of electronic
oscillation tube, cathode of high stress rectifier and separately heated
cathode heater in a variety of electronic instruments, which can perform in
hydrogen, inert gases or vacuum.
