Tungsten Alloy has become one of the essential materials for aviation application because of its high density, wear resistance and good thermal conductivity. The development of aviation industry represents a country's economic and scientific development level and is an important criterion for judging a country's comprehensive national strength. Therefore, the Chinese government strongly supports the development of this industry. With the continuous improvement of China's comprehensive national strength and the support of a large number of policies, the aviation industry has developed rapidly, while tungsten alloy has also been widely used in various aspects.

1.Counterweight

 

The Counterweight is an essential balancing device for aircraft and various aircrafts. The helicopter rotor requires absolute balance in order to keep the whole fuselage stable, and tungsten alloy can be made into blades to make up for the balance of a single blade in the helicopter; In helicopter manufacturing, tungsten alloy counterweight is quickly installed in many automatic control systems designed for propellers to prevent speeding; In addition, in the final stage of assembly, because of its high density and smaller physical size than other materials such as lead, tungsten alloy is an effective balance weight to balance the overall net weight of aircraft;

 

 

2.Navigation Bar Gyroscope

 

Navigation Bar Gyroscope is a key accessory in aerospace industry, which has high requirements in manufacturing and mechanical properties. Under the influence of its own motion and the earth's rotation force, the aircraft will produce inertial rotation, so it is necessary to install a weight along the rotation axis to generate a correction torque around the inner ring axis, so that the gyro rotor can continuously rotate around the outer ring axis so as to correct the orientation of the gyro rotation axis at any time and measure the heading angle of the aircraft correctly. The use of tungsten alloy in gyro rotor can ensure that it can prolong its service life in high-speed rotating environment, because the precision of tungsten alloy manufactured by sintering process can reach extremely high, and it has the properties of wear resistance, high temperature resistance and easy processing.

 

3.Aircraft Brake Pads

 

Tungsten Alloy Aircraft Brake Pad is an important component which plays a deceleration role in the wheel brake device. Although the engine has been turned off during the descent of the aircraft, huge kinetic energy is still saved. From the moment of landing, the wheels rotate at high speed under the action of friction, and the braking effect is generated by the strong friction with the brake pads. The high temperature generated in this descending process has already melted and deformed for ordinary metal materials, but tungsten alloy materials still maintain good strength due to high temperature resistance, which meets the requirements of special conditions such as high temperature and high pressure generated during aircraft braking.
