ASTM B777 WNiCu Machined Tungsten Heavy Alloy Bars

ASTM B777 WNiCu Machined Tungsten Heavy Alloy Bars

Tungsten Heavy Alloy Bars have high density, high strength, high hardness (known as 3 H alloy) and good ductility, electrical conductivity and thermal conductivity. Because of its comprehensive excellent performance, it plays an important role in weapon manufacturing, and then it is widely used in the national defense industry, aerospace and civil industry, such as the electrical industry, drilling industry, etc. High proportion tungsten alloy material has become a kind of dual-use alloy material that attracts much attention.

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.
