Tungsten Alloy Ring

Tungsten-nickel-ferroalloy is based on tungsten (about 90 ~ 98%) and added nickel, iron, copper or other components of the alloy, also known as high specific gravity tungsten alloy (WHA), the specific gravity is generally 17.0 ~ 18.5. It has good plasticity and machinability, good thermal and electrical conductivity, and has excellent absorption capacity for gamma rays or X-rays. It is mainly used in the manufacture of gyroscope rotor, guiding device and shock absorber for aviation and aerospace equipment. Die casting die, knife clamp and automatic watch weight, etc.; Riveting heads and switch contacts for electrical products; In addition, it is also used to manufacture various shielding parts for ray prevention.

Advantages of tungsten-nickel alloy:

*specific weight: the general gravity is 16.5-18.75g/cm3;

* High strength: tensile strength of 700-1000Mpa;

* High thermal conductivity: the thermal conductivity of tungsten alloy is 5 times that of die steel;

* Strong absorption of rays: 30-40% higher than lead;

*The coefficient of thermal expansion is small: only 1/2-1/3 of iron or steel,

*Good conductivity; Because of its good electrical conductivity, it is widely used in lighting and welding industry

* Good weldability and workability.

It is widely used in aerospace, aviation, oil drilling, electrical instrumentation, medicine and other industries.
