high density tungsten nickel copper W-Ni-Cu alloy machined parts counterweight

Tungsten-nickel-copper alloy is a kind of alloy composed of tungsten matrix with a small amount of nickel-copper and other alloying elements. It has the following characteristics: high density (~18.8g/cm3) and adjustable, strong ability to absorb high-energy rays (1/3 higher than lead's ray absorption coefficient), low thermal expansion coefficient (4~6 10-6/), good plasticity, high strength and elastic modulus, machinability and weldability.
Widely used in ray protection and guidance, industrial counterweight parts, safety and defense parts, etc.

Tungsten nickel alloy performance

- large proportion: ~ 18.8 g/cm3 density.
High strength: tensile strength of 700-1000MPa;
- Strong ray shielding ability: Under the same thickness condition, the ray shielding ability of tungsten alloy is more than 1.7 times that of lead. When the ray is stronger, the difference between the two ray shielding ability is more obvious;
- Large thermal conductivity: the thermal conductivity of tungsten alloy is 5 times that of die steel;
- Small thermal expansion coefficient: tungsten thermal expansion coefficient 4~6 10-6/, only 1/2-1/3 of iron or steel;
- Good molding machinability and weldability;
- Compared with lead's toxicity, tungsten alloy material has environmental protection characteristics, and it is not harmful to human safety when using tungsten alloy shielding parts to manufacture radiation detectors;
- Compared with tungsten-nickel-iron alloy, tungsten-nickel-copper alloy has no magnetism, and tungsten-nickel-iron alloy has better mechanical properties and processing properties than tungsten-nickel-copper alloy.

Applications for Tungsten Alloy Plate:
Tungsten alloy plates are produced by good processing property billets and special cold and hot rolling technology; they can be used to make tungsten target, tungsten heat elements, tungsten radiation shields and tungsten channels for electronics, lightening, electro-vacuum industries.

Tungsten alloy plates play very important role in manufacturing of collimator for nuclear medicine, nuclear research, geological prospecting and security inspection. These materials provide reliable protection against X-rays and gamma radiation.
