Tungsten Alloy Counterweight For Aviation

This counterweight material has an extremely high density, typically ranging from 16.5 to 18.5 g/cm³-about 50%-60% heavier than lead and roughly 130% heavier than steel. Additionally, it offers excellent mechanical properties, making it suitable for both dynamic and static applications.

Tungsten alloy aircraft counterweights can also be used on satellites. Tungsten alloy aircraft counterweights help to accurately locate the center of gravity of the satellite to ensure its correct flight trajectory.Tungsten alloy counterweights are critical components in the aviation field, used to balance and optimize aircraft performance. They are commonly applied in aircraft control surfaces, helicopter rotor blades, balance wheels, and turbines.

Tungsten alloy counterweights have high density, small volume, low thermal expansion, high strength, and excellent wear resistance. Being environmentally friendly and non-toxic, they reliably withstand high stress and extreme temperatures in aircraft applications. Their superior machinability and material compatibility ensure optimal flight safety and performance enhancement.

High Density and Small Size:
Tungsten alloy has a very high density, so it can provide more weight in a small space. This is especially important for aviation applications where space is limited. For example, a tungsten counterweight of the same weight is only 60% the size of a lead counterweight, greatly reducing the part's volume.

Low Thermal Expansion:
Its thermal expansion coefficient is low (4-6×10⁻⁶/°C), meaning it stays stable even under extreme temperature changes. This is crucial for aircraft performance in different flight conditions.

High Strength and Wear Resistance:
Tungsten alloy is very strong and wear-resistant, allowing it to handle high stress and friction during aircraft operation.

Eco-Friendly and Safe:
Unlike traditional lead, tungsten alloy is non-toxic and environmentally friendly. It also resists creep, meaning it keeps its shape well even at normal temperatures.

Machinability and Compatibility:
Tungsten alloy is easy to machine and can be joined with other materials through mechanical fastening, brazing, or shrink fitting.

Aircraft Control Surface Counterweights:
Used in parts like elevators, rudders, and ailerons to improve flight control. These counterweights help keep the aircraft balanced and stable during flight.

Helicopter Rotor Blade Counterweights:
Used for static and dynamic balancing of rotor blades to reduce vibration. Adding tungsten alloy counterweights improves rotor performance and extends blade life.

Vibration Damping Devices:
In aircraft engines and transmission systems, tungsten counterweights reduce vibration, making the system more reliable and efficient.

Load Simulation in Flight Testing:
During flight tests, tungsten counterweights can simulate different load conditions to find the best placement for balance.

Avionics Components:
Tungsten alloy is also used in avionics, such as gyroscopes, where high-density materials are needed for precise balance and control.
