ASTM 777 90WNiFe Heavy Tungsten Alloy Cube For CounterweightTungsten heavy alloy cube has high density, high strength, high
hardness (commonly known as 3H alloy) and other excellent
comprehensive properties, with good ductility, thermal conductivity
and thermal conductivity.It plays an important role in
weapons-making.It is widely used in national defense industry,
aerospace and civil industry (such as electrical industry, drilling
industry, etc.).High specific gravity tungsten alloy material has
become both military and civilian alloy materials.
Tungsten alloy metals mainly include W-Ni-Fe and W-Ni-Cu, which are
widely used in military equipment, machinery manufacturing,
aircraft parts, medical shields and sports equipment.WNiFe / WNiCu
Heavy tungsten Alloy
Our W-Ni-Fe alloy is used for the collimator and shielding
components to provide x-ray and gamma-ray protection Tungsten Heavy Alloy Cube Bloc SPECIFICATION &

Heavy Tungsten Alloy Cube Picture:
Introduction & Features of Tungsten Heavy Alloy Cube Block- Tungsten heavy alloy cube is mainly divided into two series:
tungsten nickel and copper, even tungsten nickel copper.In
contrast, western Nickel alloy has better mechanical properties and
plays an important 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 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 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 Tungsten Heavy Alloy Cube Block- Die-casting is a precision casting process with small chips and no
chips.Complex-shaped parts can be made directly.Process plate, high
yield rate, no holes, save raw materials.Especially in the iron
metal die-casting process, the working condition of the
single-phase crystallizer is very poor.It must be able to withstand
high temperature, high pressure and metal flow corrosion, as well
as corrosion resistance, oxidative and thermal shocks.High specific
gravity tungsten alloy has good thermal conductivity and corrosion
resistance.This is a very good die-casting material.Compared with
the copper mold, the service life can be increased by dozens of
times.
