Introduction and Characteristics of Tungsten Alloy Beads

Tungsten heavy alloys contain 90% to 98% tungsten, which is responsible for their high density (16.5 to 19.00g/cc). Nickel, iron and/or copper are used as metal binder bases to hold fragile tungsten particles together, making tungsten alloys tough and easy to use. 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 some tungsten is brought into the solution to form a microstructure through which large tungsten particles (20-60μm) are dispersed in the matrix alloy.

Application of Tungsten Alloy Beads

Application in aviation industry

  • An important use of high specific gravity tungsten alloy is for the lifting control and rudder balance device of aircraft and helicopter, the control device of aircraft wing and rudder and the damping device of aircraft. It is used as static and dynamic balance weight and damping device of rotor blade on helicopter.
