High Density Tungsten Heavy Alloy WNiFe/WNiCu Plate With Density of
16.8-18.8g/cm3
Introduction of Tungsten Heavy Alloy
Tungsten based high specific gravity alloys are also known as
high-density tungsten based metals or high specific gravity
tungsten alloys which is an alloy material based on tungsten
(tungsten content is generally 80% ~ 98%) and composed of a small
amount of Ni, Fe, Cu, Co, Mo, Cr and other elements,
There are two kinds of tungsten heavy alloys: tungsten nickel iron
alloy (weak magnetic) and tungsten nickel copper alloy
(non-magnetic).
Properties of WNiFe Tungsten Heavy Alloy
Tungsten heavy alloy, WNiFe alloy is characterized by high
strength, high hardness, good conductivity and thermal
conductivity, low thermal expansion coefficient, corrosion
resistance and oxidation resistance, good machinability and
weldability, and have a series of excellent physical properties and
usability performance. In addition, tungsten heavy alloy, tungsten
nickel iron has excellent absorption capacity for y-ray or X-ray.
Applications of WNiFe Tungsten Heavy Alloy
Tungsten nickel iron alloy is widely used and has become the main
tungsten based heavy alloy with large consumption. As general
applications, such as counterweights, radiation shielding devices,
etc., sintered WNiFe alloys are directly used; However, for
applications requiring high mechanical properties, the WNiFe alloy
just needs deformation processing and heat treatment to achieve
strengthening.
Tungsten Heavy Alloy Specification:
| class | Tungsten weight% | Density g/cc | Hardness MAX |
| 1 | 90 | 16.85-17.25 | 32 |
| 2 | 93 | 17.15-17.85 | 33 |
| 3 | 95 | 17.75-18.35 | 34 |
| 4 | 97 | 18.25-18.85 | 35 |
The density of tungsten heavy alloy is very high. Its density is
twice of steel. Tungsten heavy alloy has low thermal coefficient
but it has high absorption ability and high-energy rays. The
tungsten heavy alloy we make conforms to ASTM B777-99 standard.
It is massively applied to balancing weight mould and high
temperature moulds. Also they can be made into protective shield
and high-energy rays. The tungsten heavy alloy conforms to ASTM B
777-99 standard.
