Tungsten Alloy Music

Tungsten products generally includes everything from household items to aerospace technology. The metal is almost as dense as gold and has the highest melting point of any metal in purest form at 6,192°F (3,422°C). These properties popularize the use of tungsten in many applications. Tungsten has a wide range of industrial use when combined with other elements and industrial metals to make tungsten heavy alloy.

tungsten alloy rod


Most of the major applications for tungsten alloy rods are based on its very high density where it is used to control or distribute weight in some way. Tungsten heavy alloy rod could be machined further.
They are usually used to making the parts of counterweight, radiation shielding, military defense appliance, welding rod, extrusion die. Some sports facilities are also use it, such as darts, billets, golf club, etc. In addition, we can manufacture and offer tungsten alloy rods as the counterpart of Anviloy 1150, whose properties are much similar.

Tungsten wire

The resistivity of tungsten is 5.3 * 10 ^ -8, high melting point of tungsten, resistivity, strength, vapor pressure, is all pure metals, the production of incandescent filament tungsten best material. With the development of science and technology, theprogress of human civilization, the requirements of life getting higher and higher,more and more close to nature. Had phased out incandescent tungsten done,replaced by fluorescent lamps. Fluorescent lamps not only can emit white light nearthe sun's rays, but also energy saving, energy-saving lamps in China.
Tungsten is now still widely used in the heating industry, because the tungsten resistivity and high temperature resistance determines the popularity of tungsten inthe heating industry.

tungsten alloys

Tungsten material is also made into tungsten carbide product, which is a chemical compound that contains carbon and tungsten and is similar to titanium carbide. It was originally developed for use as a cutting tool, in machine tools applications, where it still finds wide use today. Cemented tungsten carbide is neither a metal nor is it a ceramic, which are prepared by reacting carbon and tungsten at a temperature of between 1400-2000ºC. With its highest hardness as 86~93 HRA (68~81HRC), however, it is not called tungsten alloys, but tungsten carbide, because its superior wear resistance and high cutting speed,. Besides, as it is easily brickle, tungsten carbide is widely used as cutting blade, drill, bits, nozzles, etc. but not for crack resistance, tungsten alloys are usually widely used as tungsten alloys radiation shielding, tungsten alloys crankshaft, tungsten alloys counterweight, which is usually made of tungsten alloys materil with its special properties as good elongation, small capacity with high density, good corrosion resistance, wonderful shock resistance, high radiation adsorption capability, etc.

tungsten heavy alloys

The matrix alloy melts and takes some tungsten into solution during liquid phase processing, resulting in a microstructure through which large tungsten grains (20–60µm) are dispersed in the matrix alloy. The as-sintered material often is subjected to thermo mechanical processing by swaging and aging, which results in increased strength and hardness in the heavy alloys.

Tungsten alloy is now well known as the best material for this significant role of golf club balance weight. You can have a general impression for how tungsten alloy is applied to balance the golf club’s better control from the below pictures demonstration.

Tungsten nozzle

Tungsten nozzle can be manufactured from the material of pure tungsten, tungsten alloy and tungsten carbide. They have different prosperities, such different density, the density of pure tungsten nozzle is about 19.2~19.3g/cm3, the density of tungsten alloy nozzle is about 15-18.5g/cm3 and the density of tungsten carbide nozzle is about 14.4-1g/cm3.

Tungsten boat

Tungsten boats sources are used for the vacuum evaporation of materials that are in granular or pellet form. They can also be used to evaporate small lengths of wire or to evaporate materials which would not properly "wet" the surface of an evaporation filament. These boats are ideal for use in small evaporation systems, such as bell jars, for experimental and prototype work.

Tungsten filament

Tungsten filament is a product existed when the bulb with tungsten filament is invented and has a long history. Since tungsten filament has gone through so long history, it has been created with kinds of shapes to match different bulb, such tungsten filament in the room, tungsten filament in the car, tungsten filament in the motorbike, and so on. All the applications has promoted tungsten filament to be more fashion and applicable.
