Descr1ption:
Tungsten heavy alloy, also known as high density tungsten base alloy, is specially made by adopting tungsten as matrix and adding nickel, iron, copper and other metal components in appropriate proportion. In terms of the alloy, tungsten content commonly accounts for 90% and the relative density is above 17g/cm3. Tungsten heavy alloys can be divided in two major kinds: tungsten nickel copper alloy system and tungsten nickel iron alloy system. Tungsten heavy alloys fromall comply with Standard ASTM B777-99.

Application:
1.Tungsten heavy alloys are mainly applied in aerospace industry, damping devices, conventional weapons, radiation shielding devices and parts;
2.They are also used for die mold in machinery manufacturing, flywheel and automatic watch pendulum;
3.They're also adopted in electrical equipment contacts and electrodes, etc.

Features:
1.Tungsten heavy alloys are of high density, high strength and good conductivity thermal characteristics;
2.The properties of high density tungsten base alloy help to reduce the processing temperature, simplify the production process and improve the alloy plasticity and processing performance;
3.In terms of engineering materials, tungsten heavy alloy is much easier to conduct than pure tungsten because of its better mechanical property.

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.The tungsten heavy alloys from comply with Standard ASTM B 777-99.
