Manufacturer of tungsten heavy alloy for more than 20 year experience from China–Zhuzhou Jiuding Metal Technology Co., Ltd.

What is tungsten heavy alloy?

composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added with Co? Mo?Cr, etc. They have very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Tungsten content in conventional heavy alloys varies from 90 to 98 weight percent and is the reason for their high density (between 16.5 and 18.75 g/m3). Nickel, iron and copper serve as a binder matrix, which holds the brittle tungsten grains together and which makes the alloys ductile and easy to machine. Nickel-iron is the most popular additive, in a ratio  of 7Ni:3Fe or 8Ni:2Fe (weight ratio). The conventional processing route for tungsten heavy alloys includes mixing the desired amount of elemental powders, followed by cold pressing and liquid phase sintering to demanded density. 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.

Main properties of tungsten heavy alloy

There are many special performance of tungsten heavy alloy, e.g., small volume but high density (between 16.5 and 18.75 g/cm3), high melting-point and hardness, excellent abrasive resistance, high ultimate tensile strength, good ductility, low vapor pressure, high temperature resistance and good thermo stability, easy to machine, anti-corrosion, better resistance to shock, sky-high absorbing ability of radiation, excellent anti-striking ability and anti-fracturing ability, Besides, it is a kind of non-poisonous and environmental friendly material which conforms to international environment protection standard.

Main application of Tungsten Heavy Alloy

There are many kinds of tungsten heavy alloy products, with different manufacture techniques various shapes could be made, such as tungsten heavy alloy rod, cylinder, bar, block, brick, plate, tip, strip, sheet, ultra thin sheet, sphere, pellet, ball, disc, ring, tube, etc. They could be used in different fields depend on their special properties, such as small capacity but high density, high yield strength, good hardness, excellent elongation, etc. When it comes to different functions, tungsten heavy alloy could be widely used for different industries and countries in various fields: such as the sports, including golf, fishing, darts, yacht, racing car; the medical, including radiation shielding, source holder, collimator, isotope container, nuclear syringe; the scientific, including tungsten heat sinks, oil drill, mine exploitation. Due to increasing abundant demand of Depleted Uranium, tungsten alloy is also widely used as a substitution in some parts of military products nowadays. As its high density similar to real gold, tungsten alloy material is very famous as gold-plated substitution. It could be made as gold-plated tungsten bar, golden tungsten brick, gold-plated tungsten bar, golden tungsten paperweight, gold-plated tungsten coin. For its high melting point, tungsten alloys are usually used for many high temperature working environments, such as rocket ignitron, turbine, etc. For its environment-friendly, tungsten alloy material is widely made as tungsten heavy alloy fishing sinker, jig, weights, it is much better than lead in small capacity but high density. Depending on special properties, tungsten heavy alloy is very popular in our life now.

Zhuzhou Jiuding Metal Technology Co., Ltd.

Established in 2001, Zhuzhou Jiuding Metal Technology Co., Ltd is a professional joint venture company which engages in manufacturing, machining and sales of tungsten heavy alloy, tungsten copper, cemented carbide, pure tungsten and other relevant tungsten alloy products. Our products mainly include tungsten heavy alloy, tungsten carbide, tungsten alloy fishing sinker, tungsten darts, tungsten Alloy swaging rod, bucking bar, copper tungsten electrode, tungsten alloy bullets, tungsten alloy syringe, tungsten alloy shielding vial, tungsten alloy boring bar, etc. Due to its characteristics of high density, high hardness, high melting point, anti-corrosion, radiation protection, non-toxic and environmental-friendly, therefore, our fragmentation is a natural under the action of detonation products, the shell expansion, fracture broken is made of such warheads is characterized not only as a container shell to form another anti-elements, fragments the size of the shell is uneven, irregular shape in the air fast decay in flight speed, so that the effective anti-personnel grenade limited in scope.

Pre-control use of shell fragments groove, groove or increase the lining of explosives and other technical measures to make the shell partial reduction of the intensity to control the  explosion of the broken parts to form fragments. Such warheads are characterized by the  formation of fragment size of the uniform, shape the ground rules.

Prefabricated fragments forming a pre-processing will be the shape and quality of pre-designed steel ball, steel arrows, tungsten ball, tungsten and other prefabricated column fragments produced prefabricated sets of body fragments, and installed in the grenade projectile outer surface or inner surface. These prefabricated projectile fragmentation grenade explosion with the formation of fragments together constitute the natural fragmentation field, due to resistance of prefabricated fragments flying characteristic consistency, with prefabricated fragments of the grenade will be set within the framework of the lethal effect of a relatively dense, full-bombs a greater degree of lethality increase.

Because there is a prefabricated fragments will affect the negative effects of missile body structures, usually only in low-pressure chamber which uses artillery and ammunition, such as the forced large-caliber bullets and grenades. Applications also are the most common aircraft shells, grenades, mines and so on. The current high chamber pressure prefabricated artillery fragments, are used in canister form, such as Switzerland, L70-type 40 mm grenade where overhead is filled with tungsten carbide ball. Prefabricated fragments technology has been widely used on all types of warheads. Cylindrical fragments (Tungsten column) as a type of prefabricated fragments, due to high density, armor-piercing capability, as air defense, anti-radiation, anti-surface, one of the main anti-elements, and widely used.
