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.
