90WNiCu Tungsten Nickel Copper Alloy Plates For Shielding Part 16.85~17.25 Density
Introduction of tungsten heavy alloy shielding part
Tungsten alloy shield is a device used to shield radioactive substances to avoid injury. It is ade of tungsten alloy material, it is a radiation shielding material that can be well used to replace lead and steel
Applications of Tungsten Nickel Copper Alloy:
First, WNiCu alloy can be used as shielding material, which has good absorption effect for X-ray and gamma ray, and is suitable for the field of ray shielding sensitive to magnetic environment;
Second, WNiCu is used as the electrical contact of high-voltage electrical switch and the electrode for electrical processing, which is mainly due to the strong conductivity and good high temperature resistance of the alloy;
Third, it is used as gyroscope rotor and some equipment that need to work in the magnetic field environment, because it has good diamagnetic performance;
Fourth, applied as various counterweights.
Properties of tungsten heavy alloy:
1. Good radiation shielding ability
2.Smaller volume and thickness
3.Good corrosion resistance, higher strength
4.Excellent machinability
