Product Description

WNiFe/WNiCu tungsten heavy alloy
WNiFe/WNiCu tungsten heavy alloy is produced by pressing and sintering metal powders into billets, which are worked by rolling or swaging into
kinds of shapes. Smaller sizes are produced by subsequent drawing. Tungsten heavy alloy is produced in straight random lengths with a smooth swaged surface at diameters 3mm and larger, and with a smooth drawn finish below 3mm. A centerless ground finish can also be furnished. Specific lengths and special fabrications can be supplied upon request.

Tungsten Heavy Alloy Rod
Tungsten heavy alloy (tungsten nickel iron, WNiFe & tungsten nickel copper, WNiCu) contains 80%-98% tungsten in combination with  small amounts of the other metals. Beginning in powder form, the desired elements are alloyed in a compacting and sintering process.

Applications:
Tungsten heavy alloy is excellent in applications requiring high performance in corrosion resistance, density, machinability, and
radiation shielding. Therefore, this makes it ideal for use in specified steelmaking, mining, aerospace, and medical industries.

Tungsten nickel iron contains 1% to 3% of iron and 1% to 7% of nickel composited at ratios ranging from FeNi 1:1 to 1:4. 
The 1% to 3 % of iron additive is responsible for significant differences in tungsten alloys containing nickel iron exhibit, comparing tungsten alloys containing nickel copper. 
First, tungsten nickel iron is ferromagnetic material because of the iron. Iron imparts other special attributes to tungsten nickel iron, such as its comparatively higher density, melting point, ductility, and
strength. 
By virtue of these excellent properties, tungsten nickel iron alloys have better high-temperature strength and higher cold-work
deformation rate than tungsten nickel copper.

Tungsten nickel copper contains 1% to 7% of Ni and 0.5% to 3% of Cu composited at ratios ranging from Ni to Cu 3:2 to 4:1.
Nonmagnetic and high conductivity are two outstanding properties of tungsten alloys with nickel copper binders. 
Tungsten nickel copper alloys are preferable material in applications such as aerospace and electronic devices requiring non-magnetic working conditions and high thermal and electrical conductivities.

Applications for tungsten heavy alloy
These kinds of tungsten heavy alloy can be machined further into the parts of counterweights, radiation shielding, military defense appliances, welding rods, extrusion dies or radiation shielding. Some are used in sports to create darts, billets, golf club, etc.
We manufacture and offer tungsten alloy rod that can be used as the substitute for Anviloy 1150, with very similar properties.
With tungsten alloy rod high density, high melting point, small capacity, excellent hardness, superior wearing resistance, high
ultimate tensile strength, etc. tungsten alloy rod is increasingly popular material.
