Heavy Tungsten Alloy BricksHeavy 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.

Heavy Tungsten Alloy Bricks Picture:
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.
