Descr1ption of high density tungsten alloy :
Tungsten heavy alloy generally is refractory metal, which have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe. They are materials mainly with over 85% tungsten and low amounts of chemical elements, such as Ni,Fe ,Cu,Co,Mo,Cr, etc.  produces tungsten heavy alloys with density ranges from 16.8g/cm3 to 18.75g/cm3. 

Applications of high density tungsten alloy:
1.Tungsten heavy alloy can be widely used as balancing weights and high temperature moulds;
2.They can also be used as protection shields for high-energy rays;
3.Electro-heat upsetting anvil block and the core of armour piercing shell also adopt tungsten heavy alloy as material;
4.They are also offered as machinable blanks or precision machined parts according to customers’ requirements;
5.Tungsten heavy alloys also can be used for producing aircraft control surfaces, helicopter rotor systems, engine components, ship ballasts, golf club weights, boring bars and down hole logging-sinker bars, etc;
6.They can be produced as the materials for making fire arms and ordnance.

Features of high density tungsten alloy:
1.Tungsten heavy alloy has a very high density between 16.8g/cm3 to 18.75g/cm3, which is twice as much as of steel and more than 50% heavier than lead;
2.It is of low thermal expansion coefficient, high strength and high modulus of elasticity;
3.It has high absorption capacity of high-energy rays;
4. comply with Standard ASTM B 777-99.
