Introduction and characteristics of WNiFe Tungsten Balls 

  1. Tungsten heavy alloys contain between 90% and 98% tungsten, which is responsible for their high density (16.5 to 19.00g/cc). Nickel, iron and/or copper are used as metal bonding substrates to hold fragile tungsten particles together, making tungsten alloys strong and easy to work with. Nel is the most commonly used additive with a ratio of 7Ni: 3Fe or 8Ni: 2Fe (weight ratio).
  2. 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, bringing some tungsten into the solution and forming a microstructure through which large tungsten particles (2060 m) disperse in the matrix alloy.


Application of  WNiFe Tungsten Balls 

  • In the design and development of shell piercing projectile, the high proportion of tungsten alloy is an effective technical measure to improve the core kinetic energy and armor piercing ability. In the 1970s, the opening hours were shorter. At present, in addition to the high gravity tungsten alloy cores used in the United States, many Western European countries also use them accordingly.
