Product Description

95WNiFe ASTM B777 High Density Tungsten Alloy Block

Tungsten Alloy Block has comprehensive excellent properties such as high density, high strength and high hardness (commonly known as 3H alloy), as well as good ductility, conductivity and thermal conductivity. It plays an important role in weapons manufacturing. Then it is widely used in national defense industry, aerospace and civil industry (such as electrical industry, drilling industry, etc.). High gravity tungsten alloy material has become a kind of military and civil alloy material.

Introduction & Features of Tungsten Alloy Block

Tungsten Alloy Block is mainly divided into W-Ni-Fe and W-Ni-Cu, even W-Ni-Fe-Cu two series. In contrast, W-Ni-Fe alloy has better mechanical properties and plays a great role in various fields of defense industry and national economy. It is a very important new military material in national defense industry and has been gradually extended to various civil industries.


The tungsten content in tungsten heavy alloys varies between 90% and 98%, which accounts for their high density (16.5 to 19.00 g/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 use. Ferric nickel Nickel is the most commonly used additive with a ratio of 7Ni:3Fe or 8Ni:2Fe (by weight).


Application of Tungsten Alloy Block

  • Die casting is a kind of precision casting process with less chips and no chips, which can directly manufacture components with complex shapes. Process sheet, high yield, no holes and saving raw materials. Especially in ferrous metal die casting, the working conditions of phase I die are very harsh. It must withstand the scouring of high temperature, high pressure and metal flow, and can resist corrosion, oxidation and thermal shock. High specific gravity tungsten alloy is a good die casting die material because of its good thermal conductivity and corrosion resistance. Compared with copper die, it can improve the service life by tens of times.
