Tungsten Heavy Alloy
Tungsten heavy alloys generally are refractory metal, which have two-phase 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.

Product Description

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.
