Machined 90WNiCu High Density Tungsten Heavy Alloy Ring
Tungsten Heavy Alloy Ring has high density (density higher than 60% of lead), good mechanical strength, small thermal expansion, good corrosion resistance, high radiation absorption capacity (higher than lead), simple economic cycle, high strength, high density tungsten alloy tube, suitable for manufacturing radiation shielding elements. High-density tungsten alloy tubes have the same radiation shielding capacity as lead, while reducing the volume and thickness of the shielding vessel. Compared with lead and depleted uranium, tungsten alloy also has the advantages of non-toxic and pollution-free. High gravity tungsten alloy tube is mainly used for shielding vials and syringes.
What is Tungsten Heavy Alloy Ring?
- Heavy tungsten alloys are usually composed of wNFE-Fe, WNNI-Cu or even WNNI-cu-Fe. Some tungsten alloys also add cobalt, molybdenum, cadmium, and other metallic elements. It can be made into any shape. High gravity tungsten alloy tube is often used for nuclear shielding and military products, such as counterweights for hunting guns, hunting equipment, missiles, armor-piercing bullets, oil RIGS and so on.
- Heavy tungsten alloy has a series of excellent characteristics, the proportion is significant: generally accounted for 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong light absorption capacity: 30-40% higher than lead, large thermal conductivity: 5 times that of die steel; Small thermal expansion coefficient: only 1/2-1/3 of steel capacity, good thermal conductivity, good weldability, good machinability.
Application of Tungsten Heavy Alloy Ring?
1. Gyroscope components
Gyroscope is the core of navigation and control system of satellite, aircraft, various missiles and spacecraft. The stability of gyroscope is proportional to its rotating mass. The rotor of the gyroscope rotates at more than 20,000 RPM during operation, so the material needs to be strong enough to withstand centrifugal force, and high gravity tungsten alloy is the ideal material.
2. Application in missiles
In addition to being used for gyro rotors, it is also used in missile guidance devices.
