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 substrates to hold fragile tungsten particles together, making tungsten alloys tough and easy to work with. 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.
In the design and development of shell piercing shells abroad, the use of high specific gravity tungsten alloy is an effective technical measure to improve the core kinetic energy and the ability of piercing shells. Foreign countries attach great importance to this. It began development in the early 1970s and became operational within a short time. At present, in addition to the use of high gravity tungsten alloy core materials in the United States, many western European countries also use the corresponding.
