Heavy Tungsten Alloy Bricks
Heavy Tungsten Alloy Bricks have high density, high strength, high hardness and other excellent comprehensive performance (commonly known as 3H alloy), with good ductility, thermal conductivity and thermal conductivity.It plays an important role in weapons manufacturing.It is then widely used in national defense industry, aerospace and civil industry (such as electrical industry, drilling industry, etc.).Tungsten alloy with high specific gravity has become a military and civilian alloy material.

Introduction & Features of Heavy Tungsten Alloy Bricks
- Tungsten alloy cube is mainly divided into two series: W nickel and iron and W nickel and copper, and even W nickel and iron and copper.In contrast, Si Ni Fe alloys have better mechanical properties and play an important role in various fields of the defense industry and the national economy.It is a very important new military material in the defense industry, and has gradually expanded to various civilian industries.
- The tungsten content of the heavy tungsten alloy 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 metal bonding substrates to hold 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 Bricks
- Die-casting is a precision casting technology with less chips and no chips.It can directly make parts with complex shapes.Process plate, high yield, no holes, save raw materials.Especially, the single phase die works very poorly.It must be able to withstand 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.Is a very good die-casting material.Compared with the copper mold, the service life can be increased by dozens of times.
