Tungsten Alloy is an alloy produced by powder metallurgy with tungsten powder as main raw material and Fe, Ni, Co as binder. It has excellent properties such as high melting point, high hardness, high strength, high specific gravity, creep resistance, thermal conductivity and electrical conductivity, and is widely used.
I. Aerospace Industry
Rotor materials of gyroscopes, inertial rotating elements of aircraft, balance weight elements of ailerons, steering rudders, engines, rotating blades of helicopters, etc.
II. Military Industry
Small arrows bundled with arrows in bullets, "gunpowder cover", shrapnel, shrapnel, screen bullets and armor-piercing bullets in shaped charge bullets, Gyro rotor, counterweight screw, adjusting plate of missile instrument, high density alloy missile body weighing tens of kilograms, counterweight block in governor of tank engine, and shielding material for counterweight block and nuclear reactor in nuclear submarine.
III. Electrical Industry
There are many kinds of electrical equipment made of tungsten alloy, such as anvil material for electric upsetting, rivet material for electric riveting, electrode material for EDM, electric welding material, electric contact material for high voltage switch, etc.
IV. Machinery Manufacturing and Pressure Casting Industries
Machinery and instrument manufacturing industries are used as balancing elements. For example, installing tungsten alloy counterweight on the drill pipe of oil drilling rig can greatly improve the verticality of drilling, improve the oil drilling efficiency and the high temperature performance of tungsten alloy, and make it a good die material in die casting industry.
V. Medical Device Industry
Tungsten Alloy is an ideal material for shielding components or containers of various radioactive sources, such as medical tungsten needles, gamma ray collimators, anti-scattering plates, CT detectors, radiological protection doors, etc.
VI. Sporting Goods Industry
The crankshaft made of tungsten alloy can greatly improve the performance of racing car; The edge of golf ball and tennis racket is inlaid with tungsten alloy counterweight, which can make the racket have stronger attack ability; In the heavy arrow competition, when the arrow is made of tungsten alloy, the hit rate of heavy arrow can be greatly improved
.
VII. Other Industries
Since the density of tungsten alloy is similar to that of gold (19.3g/cm3 for gold and 19.0g/cm3 for tungsten alloy), it is used to make rings, necklaces and commemorative coins in souvenir and jewelry industries. Used as vibrator material of BP machine and mobile phone in electronic communication industry. In addition, it is also widely used in the fishing industry to manufacture fishing sinkers.
