High Density 95WNiFe Heavy Tungsten Alloy Blocks ASTM B777Heavy Tungsten Alloy Blocks has high density, high strength, high
hardness (commonly known as 3H alloy) and other comprehensive
excellent properties, with good ductility, electrical 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.).Supergravity tungsten alloy material has become a
military and civilian alloy material. Heavy Tungsten Alloy Blocks SPECIFICATION & CHEMICAL| Chemical Composition | 90%W | 93%W | 95%W | 97%W | | State | Sinter | Vacuum | Forge | Sinter | Vacuum | Forge | Sinter | Vacuum | Sinter | Vacuum | Density

Heavy Tungsten Alloy Blocks Picture:
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.
