Product details

Tungsten alloy, also named tungsten heavy alloy, generally is refractory metal, which has two-phase composites

consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloys are added Co、Mo、Cr, etc. They

have very high meltingpoint and have a density twice that of steel and are more than 50% heavier than lead.

Tungsten content in conventionalheavy alloys varies from 90% to 97% and is the reason for their high density

(between 16.5g/cc and 18.75 g/cc). Nickel,iron and copper serve as a binder matrix, which holds the brittle

tungsten grains together and which makes tungsten alloys ductile and easy to machine. Nickel-iron is the most

popular additive, in a ratio of 7Ni:3Fe or 8Ni:2Fe (weight ratio). Theconventional processing route for tungsten

heavy alloy includes mixing the desired amount of elemental powders, followedby cold pressing and  liquid phase

sintering to almost full density. 


Application

There are many kinds of tungsten heavy alloy products, different manufacture techniques could have various

shapes, 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.For its heavy density raging from 17.0 g/cm3

to 18.5 g/cm3, which is much denser than normal materials, tungsten heavy alloy is widely used as shielding in many

fields, such as medicine industry, aerospace research or even our daily life for mobile radiation protection. Especially,

tungsten protection acted as collimator, syringe shielding and other shield, such as X-ray protection apron, are very

important for eradiation treatment concerning X-rays, gama radiation, CT examination, etc.Besides, tungsten heavy

alloy material work as substitution to depleted uranium for nuclear radiation protection is essential to military field and

aviation. If there is need, Chinatungsten can also offer engraving or coating technique as required.
