Application Components

Engine Components

Nickel-based alloys are often used to manufacture key components of aircraft engines, such as turbine blades, combustion chambers, and turbine disks. This is because nickel-based alloys have excellent high-temperature strength, oxidation resistance, and corrosion resistance, allowing them to work stably for long periods under high temperature and high pressure.

 

Turbocharger

In turbochargers, nickel-based alloys are used to manufacture parts such as impellers and turbine housings. These parts need to remain stable under high temperature and high-speed operation. The high-temperature strength and creep resistance of nickel-based alloys make them ideal materials.

 
 

Gas Turbines

Nickel-based alloys are widely used in the turbine sections of aircraft gas turbines. These alloys can maintain their mechanical properties at extremely high temperatures, ensuring the efficient and reliable operation of gas turbines.

 

Thermal Protection Systems

Nickel-based alloys are used in the thermal protection systems of aerospace vehicles, such as the thermal protection tiles of space shuttles. These materials can withstand the high thermal flux when entering the atmosphere, protecting the spacecraft from damage.

 
 

Landing Gear

Nickel-based alloys are sometimes used to manufacture aircraft landing gear components, especially those parts that require high strength and wear resistance.

 

Structural Materials

In certain aerospace structural components, nickel-based alloys are also used as structural materials, particularly in situations requiring high strength and corrosion resistance.
