WNiCu Tungsten Heavy Alloy Plates Used in Radiation Shielding Field
WNiCu tungsten heavy alloy is composed of tungsten matrix with a small amount of nickel, copper and other alloy elements. It has the following characteristics: no magnetic, high density (~18.8 g/cm3) and adjustable, strong ability to absorb high energy rays (1/3 higher than the ray absorption coefficient of lead), low coefficient of thermal expansion (4~6×10-6/℃), processable, weldable, etc. So WNiCu tungsten heavy alloy is widely used in the field of radiation shielding and protection field which is sensitive to magnetic environment.
| Chemical Composition | Density(g/cm3) | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HRC) | Magnetic |
| W | NiCu |
| 90 | Balance | 16.85-17.25 | ≥648 | ≥517 | ≥2 | 32 | No |
| 92.5 | Balance | 17.15-17.85 | ≥648 | ≥517 | ≥2 | 33 | No |
| 95 | Balance | 17.75-18.35 | ≥648 | ≥517 | ≥1 | 34 | No |
WNiCu Tungsten Heavy Alloy Plates Performance
- non-magnetic
- high density ~18.8 g/cm3
- high strength: tensile strength 600-900 mpa
- shielding ability: tungsten alloy has more than 7 times radiation shielding ability than that of lead under the same ray thickness, the stronger the ray, the more obvious the difference between the ability of tungsten alloy and lead
- thermal conductivity: tungsten alloy thermal conductivity is 5 times of die steel
- thermal expansion coefficient is small: tungsten alloy thermal expansion coefficient 4~6×10-6/℃, only 1/2-1/3 of iron or steel
- has good plasticity, processability and weldability
- compared to lead toxic, tungsten alloy material has environmental protection characteristics, using tungsten alloy shielding parts to make radiation detectors is not harmful to human safety
Compared with tungsten-nickel-iron alloy, WNiCu has played an unique anti-jamming advantage in the sensitive to magnetic environment.
Quality Control:
1) Checking the raw material after they reach our factory. Incoming quality control(IQC)
2) Check the details before the production line operated
3) Full inspection and routing inspection during mass production. In process quality control(IPQC)
4) Checking the goods after finished. Final quality control(FQC)
