Introduction & Features of Heavy Tungsten Alloy Blocks

Tungsten alloy blocks are mainly divided into two series: W-Ni-Fe and W-Ni-Cu, and even W-Ni-Fe-Cu.In contrast, W-Ni-Fe alloys have better mechanical properties and play a huge role in various fields of the defense industry and the national economy.It is a very important new type of military material in the defense industry, and gradually expanded to a variety of civilian industries.
The content of tungsten in heavy tungsten alloys is between 90% and 98%, which is responsible for its high density (16.5-19.00g/cc).Nickel, iron, and / or copper are used as a metal adhesive substrate to bond fragile tungsten particles together to make the tungsten alloy hard and easy to use.Nickel is the most commonly used additive with a ratio of 7Ni: 3Fe or 8Ni: 2Fe (by weight).

Application of Heavy Tungsten Alloy Blocks

Die-casting is a precision casting process with less and less chips that can directly make parts with complex shapes.Single process flow, high yield, no holes, save raw materials.Especially in black metal die casting, Smi 1 working conditions are very demanding.It must be resistant to high temperature, high pressure and metal flow erosion, and can resist corrosion, oxidation and thermal shocks.High specific gravity tungsten alloy has good thermal conductivity and corrosion resistance, and is an excellent die-casting mold material.Compared with the copper mold, the service life is increased by dozens of times.
