Product Description

Standard WNiFe WNiCu Machined Heavy Tungsten Alloy Screws

Heavy Tungsten Alloy Screws is a kind of tungsten as the matrix alloy material (tungsten content is generally 80%~98%), and a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. The density of high specific gravity tungsten alloy is up to 15.20~18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as steel.

What is Heavy Tungsten Alloy Screws?

  1. Heavy tungsten alloy is mainly divided into nickel nickel iron, nickel nickel alloy, nickel copper, even tungsten alloy two series. In contrast, o - ni - fe alloy has good mechanical properties and plays an important role in various fields of national defense industry and national economy. It is a very important new military material in national defense industry and has been gradually extended to various civil industries.
  2. The tungsten content in tungsten 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 fragile tungsten particles together, making the tungsten alloy malleable and easy to work. Ferric nickel Nickel is the most commonly used additive in 7Ni: 3Fi or 8Ni: 2Fe by weight


Application of Heavy Tungsten Alloy Screws

  • High gravity tungsten alloys are used to make tool holders, especially boring bars.
  • High gravity tungsten alloy is used as the counterweight material for the high crankshaft of the small engine of forest chainsaw.
  • The electrodes of edM and electrochemical machine tools are also made of tungsten gold with high gravity
