Product Description

Machined Heavy Tungsten Alloy Disk

Heavy Tungsten Alloy Disk has comprehensive excellent properties such as high density, high strength and high hardness (commonly known as 3H alloy), and has good ductility, electrical conductivity and thermal conductivity. It plays an important role in the manufacture of weapons. It is then widely used in the defense industry, aerospace and civil industries (such as the electrical industry and the drilling industry). Supergravity tungsten alloy material has become a military and civilian alloy material.

Introduction & Features of Heavy Tungsten Alloy Disk

  1. Heavy tungsten alloy disks are mainly divided into two series: W nickel iron and W nickel copper, and even W nickel iron copper. In contrast, tungsten-nickel-iron alloys have better mechanical properties and play a huge role in the defense industry and various fields of the national economy. It is a very important new military material in the defense industry, and is gradually extended to various civilian industries.
  2. The content of tungsten in heavy tungsten alloys ranges from 90% to 98%, which is the reason for its high density (16.5 to 19.00g/cc). Using nickel, iron and/or copper as the metal binder matrix, combined with brittle tungsten particles, makes the tungsten alloy tough and easy to process. Nickel-iron is the most commonly used additive in a ratio of 7Ni:3Fe or 8ni:2Fe (by weight).


Application of Heavy Tungsten Alloy Disk

  • Supergravity tungsten alloys have been widely used in lift control and rudder balance devices of aircraft and helicopters, aircraft wing and rudder control devices, and aircraft damping devices. Static and dynamic balance weight and damping device for helicopter rotor blades.
