Application and challenge of aluminum alloy forgings in aerospace field

The aerospace field has extremely strict requirements for materials, which need to have characteristics such as light weight, high strength and high corrosion resistance. As a kind of material with excellent properties, aluminum alloy forgings have been widely used in aerospace field. This paper will focus on the application and challenges of aluminum alloy forgings in aerospace field.
The application of aluminum alloy forgings in the aerospace field
Aircraft structural parts: Aluminum alloy forgings are widely used in aircraft structural parts, such as fuselage, wing, tail and so on. Aluminum alloy material has the characteristics of light weight, high strength, high plasticity and good corrosion resistance, which can meet the requirements of aircraft for strength and stiffness, while significantly reducing the weight of aircraft and improving fuel economy.
Engine components: The engine is the heart of the aircraft, and its performance directly affects the safety and reliability of the aircraft. Aluminum alloy forgings are widely used in engine parts, such as cylinder head, piston, connecting rod and so on. Aluminum alloy material can effectively reduce engine weight, improve fuel efficiency, and has good corrosion resistance and high temperature performance.

Aerospace parts: Aluminum forgings are also widely used in other parts of aerospace, such as landing gear, control panel, seat frame and so on. These components have very high requirements for the performance and quality of aluminum alloy forgings, and need to go through strict testing and control.
Second, the challenges faced by aluminum alloy forgings in the aerospace field
High temperature performance requirements: aerospace spacecraft in high-speed flight and high temperature environment, requiring aluminum alloy forgings with excellent high temperature performance and corrosion resistance. This requires continuous research and development of new aluminum alloy materials to meet higher performance requirements.
Precision requirements: The application of aluminum forgings in the aerospace field requires high precision manufacturing to meet strict size and shape requirements. This requires continuous improvement of the manufacturing process level to ensure the accuracy and quality of aluminum alloy forgings.
Fatigue performance requirements: aerospace spacecraft will be subjected to cyclic load during service, requiring aluminum alloy forgings to have excellent fatigue performance. The evaluation and control of fatigue performance is very important to improve the safety and reliability of spacecraft.
Quality assurance and traceability: the aerospace field has extremely high requirements for product quality, and it is necessary to establish a perfect quality assurance system and traceability system. From raw materials to the production process, testing and packaging, all aspects need to carry out strict quality control and traceability to ensure the reliability and safety of products.
Technological update and progress: With the continuous development of aerospace technology, the performance and quality requirements for aluminum alloy forgings are also constantly improving. It is necessary to continuously update and improve the technology to improve the manufacturing level of aluminum alloy forgings and meet the needs of new aerospace spacecraft.
In summary, the application of aluminum alloy forgings in the aerospace field has a wide prospect, but it still faces challenges in high temperature performance, accuracy, fatigue performance and other aspects. In order to meet the requirements of materials in the aerospace field, continuous research and development is needed to improve the manufacturing process and technical level of aluminum alloy forgings, and promote the sustainable development of the aerospace industry.
