Nickel-based alloys have critical applications in Aerospace, mainly because of their excellent high temperature mechanical properties, oxidation resistance and corrosion resistance. The following is a specific overview of the application of nickel-based alloys in the aerospace field:

Aeroengine components: Nickel-based alloys are the preferred material for the manufacture of aeroengine components, especially high-temperature components. Key components such as turbine blades, guide blades, combustion chambers and nozzles inside the engine need to work in extreme environments of high temperature, high pressure and high speed, so the material is required to have good heat resistance, high strength and corrosion resistance. Nickel-based alloys, with their unique properties, have become the main manufacturing materials for these components.

Rocket engines: Similar to aircraft engines, components such as combustion chambers and nozzles in rocket engines also need to withstand extremely high temperatures and pressures. Nickel-based alloys also play an important role in the manufacture of these components due to their high temperature strength and excellent corrosion resistance.

Aerospace structure: Nickel-based alloys are also used in the manufacture of structural components of aerospace spacecraft, such as fuselage frames, wing spars and tail fins. These components need to have high strength, light weight and good corrosion resistance, and nickel-based alloys can meet these requirements to ensure the safety and performance of aerospace spacecraft.

With the progress of science and technology and the continuous development of new alloy materials, the performance and application fields of nickel-based alloys are also expanding. For example, some new nickel-based alloys have higher service temperatures and better creep and fatigue properties, providing more possibilities for the development of the aerospace field.
