W90NiFe Tungsten Heavy Alloy WIth Density of 18g/cm3 Weak Magnetic
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 nickel iron alloy is characterized by high sintering density, good strength and plasticity, and has certain ferromagnetism. WNiFe has good plasticity and machinability, good thermal conductivity and electric conductivity, and has excellent absorption capacity for y-ray or X-ray.
Applications of Tungsten Heavy Alloys
Tungsten heavy alloys are widely used in ray shielding and generating devices, nuclear power and energy components, aerospace components, electronic industry, etc
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.
