WNiFe Tungsten Heavy Alloy Rod Picture:
The tungsten content in tungsten heavy alloys ranges from 90% to 98%, which is the reason for their high density (16.5 to 19.00g/cc). Nickel, iron and / or copper are used as metal binder matrix to fix brittle tungsten particles together, making tungsten alloys ductile and easy to process. Ferronickel is the most commonly used additive in the proportion of 7Ni: 3Fe or 8ni: 2Fe (weight ratio).
Common processes for preparing tungsten heavy alloys include mixing the required amount of tungsten, iron, nickel or copper powder, and then cold pressing and liquid phase sintering to almost full density. In the process of liquid phase treatment, the matrix tungsten alloy melts, some tungsten is brought into the solution to form microstructure, and large tungsten particles (20 – 60 µ m) are dispersed in the matrix alloy through this microstructure.
In the design and development of shelled armor piercing projectiles abroad, in order to increase the kinetic energy of the core and improve the armor piercing ability, the application of high specific gravity tungsten alloy is an effective technical measure. Foreign countries attach great importance to it. It began to be developed in the early 1970s and put into use in a short time. At present, in addition to the use of high specific gravity tungsten alloy core materials in the United States, many Western European countries also use them accordingly.
