High Performance Density Tungsten Alloy Tool For Industrial PurposeTungsten 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. What is Tungsten Alloy Tool?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.
Chemical composition of Tungsten Alloy Tool| Chemical Composition | 90%W | 93%W | 95%W | 97%W | Density
(g/cc) | 16.85-17.25 | 17.15-17.85 | 17.75-18.35 | 18.25- 18.85 |
Application of Tungsten Alloy ToolTungsten 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
