Aluminum alloy has the characteristics of light weight, high strength, corrosion resistance and easy processing. It has a wide range of uses in various industries, such as decoration and decoration, electronic appliances, mobile phone accessories, computer accessories, mechanical equipment, aerospace, transportation, military, etc. field. Below we focus on the application of the lower aluminum alloy in the aerospace field.
In 1906, the German Wilm accidentally discovered that after the aluminum alloy was left at room temperature for a certain period of time, the strength gradually increased with the extension of the time. This phenomenon was later called the age hardening phenomenon, and as a core technology that Zui promoted the development of aviation aluminum alloy material technology, it attracted widespread attention. In the following hundred years, aviation aluminum workers in aluminum alloy composition and synthesis Methods, such as rolling, extrusion, forging, heat treatment and other material processing techniques, aluminum alloy parts manufacturing and processing, material structure service performance characterization and improvement, etc. have been studied in depth.
Aluminium alloys for aerospace applications We are often called aerospace aluminum alloys. They have a series of advantages such as high specific strength, good processing and formability, low cost and good maintainability. They are widely used in aircraft main structural materials. In the future, the design requirements of flight speed, structural weight reduction and stealth in the new generation of advanced aircraft will be greatly enhanced, and the requirements for specific strength, specific stiffness, damage tolerance performance, manufacturing cost and structural integration of aviation aluminum alloy will be greatly enhanced.
The following is an example of the specific use of several types of aviation aluminum alloys.
The 2024 aluminum plate, ie 2A12 aluminum plate, has high fracture toughness and low fatigue crack growth rate. It is the aircraft fuselage and wing under skin material commonly used by Zui.
The 7075 aluminum plate was successfully developed in 1943 and was the first practical application of 7xxx aluminum alloy. It was successfully applied on the B-29 bomber. The strength of the 7075-T6 aluminum alloy was high in the aluminum alloy at that time, but its stress corrosion resistance And the resistance to flaking corrosion is very poor.
The 7050 aluminum plate was developed on the basis of the 7075 aluminum alloy, resulting in better strength, resistance to spalling corrosion and stress corrosion resistance, and was applied to the compression members of the F-18 aircraft.
The 6061 aluminum plate is the 6XXX series aluminum alloy that Zui used in aviation for a long time. It has good corrosion resistance and excellent welding performance, but the strength is moderately lower.
