Tungsten alloy tools are mainly divided into nickel iron alloy, nickel copper alloy, and even nickel iron copper alloy. In contrast, wide nickel ferroalloy has better mechanical properties and plays an important role in various fields of national defense industry and national economy. It is a very important new material in the national defense industry, and is gradually expanding to various civilian industries.
Heavy tungsten alloy is a tungsten based alloy material (tungsten content is generally 80% - 98%), which contains a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. The density of high specific gravity tungsten alloy can reach 15.20~18.70g/cm3, which is also called high specific gravity tungsten alloy or high density alloy material. Because the weight of tungsten is more than twice that of alloy steel.
The common method of manufacturing heavy tungsten alloys is to mix the required tungsten, iron, nickel or copper powder, and then carry out cold pressing and liquid phase sintering until they are close to full density. In the process of liquid phase treatment, the matrix tungsten alloy melts, and some tungsten enters the solution to form dispersed tungsten particles (20~60 μ m) Structure.

Tungsten alloys with high specific gravity are used to make tool holders, especially boring bars.
The high specific gravity tungsten alloy is used as the counterweight material for the high crankshaft of the chainsaw small engine supplied by the forest every month.
Electrodes for EDM and electrochemical machine tools are also made of tungsten with a high specific gravity
