Tungsten Alloy Applied for Gyroscope of Antiship Missile

Tungsten alloy applied for gyroscope of antiship missile is an alloy composed of tungsten (W) as a matrix and Ni, Fe, Cu, Co, Mn and other alloying elements to form a composite structure of tungsten particles and bonding phase. The navigation gyroscope is the heart of navigation and control systems of antiship missiles and even submarines, torpedoes, satellites, rockets, and aircraft. At present, there are various advanced navigation technologies in the world, but the inertial guidance gyroscope is still the most widely used navigation instrument in the world.

According to the experts, in the past, the outer rotor body of the gyroscope was mostly made of copper or steel with low accuracy and poor stability. During World War II, the United States has used 90W-6Ni-4Cu instead of copper (or steel) as the outer rotor to significantly improve the accuracy and stability of the instrument. Well, tungsten alloy gyroscope at this time may not be used for anti-ship missiles as the earliest anti-ship missile in the world was the HS-292 anti-ship missile developed by Germany at the end of World War II.
