In order to improve the stability and control accuracy of gyroscope rotation, the rotor should be made of high-density tungsten alloy. Compared to gyroscope rotors made of lead, iron, or steel materials, tungsten based alloy rotors not only have greater weight, but also have longer service life, stronger oxidation resistance, better corrosion resistance, and heat resistance, thus further expanding the range of gyroscope applications.

Spiral instrument is a rigid body that rotates at high speed around a pivot point, designed based on the theory of conservation of angular momentum. It is widely used in various fields such as science, technology, and military, such as rotary compasses, directional indicators, and projectile flipping.
According to different purposes, it can be divided into sensing gyroscope and indicating gyroscope. Sensor gyroscopes are used in automatic control systems for aircraft motion as horizontal, vertical, pitch, yaw, and angular velocity sensors; Gyroscopes are mainly used for indicating flight status and serving as driving and navigation instruments.
From this, it can be seen that the gyroscope is an important directional sensing device. To improve its control accuracy and stability, the quality of its rotor is particularly crucial. Tungsten based alloys have become their preferred raw materials due to their excellent physical and chemical properties.
It is worth noting that tungsten based alloys differ in mechanics, electricity, thermodynamics, magnetism, and other aspects due to the different doping elements. For example, according to different magnetic properties, it can be divided into magnetic alloys and non-magnetic alloys. At present, tungsten based alloys include tungsten copper alloy, tungsten silver alloy, tungsten nickel iron alloy, tungsten molybdenum alloy, tungsten rhenium alloy, etc. Therefore, producers should manufacture corresponding alloy rotors based on their actual application situations.
