Introduction and characteristics of Tungsten Heavy Alloy Bars

The tungsten content in tungsten heavy alloys varies from 90% to 98%, which is responsible for their high density (16.5 to 19.00g/cc). Nickel, iron and/or copper are used as a metal binder base to hold the brittle tungsten particles together, making the tungsten alloy malleable and easy to work. Nickel-iron is the most commonly used additive, with a ratio of 7Ni:3Fe or 8Ni:2Fe (weight ratio).


Common processes for preparing tungsten heavy alloys include mixing the desired amount of tungsten, iron, nickel or copper powder and then cold pressing and liquid phase sintering to almost full density. During the liquid phase treatment, the matrix tungsten alloy melts and brings some tungsten into the solution to form a microstructure through which large tungsten particles (20 -- 60μm) are dispersed in the matrix alloy.


Application of Heavy Tungsten Heavy Alloy Bars

In order to increase the kinetic energy of projectile core and enhance the ability of piercing armor, the application of high specific gravity tungsten alloy is a successful technical measure in the design and development of shell piercing projectile abroad. At present, in addition to the United States, many countries in Western Europe have adopted tungsten alloy projectile core materials.
