Tungsten alloy gyroscope rotors have a simple structure, good abrasion resistance, and a long working life. It is well known that gyroscopes are the heart of navigation and control systems such as satellites, rockets, missiles, aircraft, submarines, and torpedoes. The stability of a gyroscope is improved with the increase in the weight of the gyroscope.

Tungsten heavy alloys have many special properties such as high density, high melting point, wear resistance, high tensile strength, good elongation capacity, low vapor pressure, excellent thermal stability, high radiation absorption capacity, etc. Due to these advantages, a tungsten alloy gyroscope rotor can be used for a long time even in high-speed rotating environments. Moreover, the use of tungsten alloy as the rotor of the gyroscope can greatly improve its stability and control precision.

Currently, although various advanced navigation technologies have emerged in the world, gyroscopes, as inertial guidance, are still the most widely used navigation instrument in the world. When dissecting an aircraft, it is found that directional gyros, vertical gyros, and speed gyros are used as outer rim rotors with high-density tungsten alloy.
