How aluminum sheets are used to make aircraft
The aircraft industry is considered to be the most advanced industry, and the requirements for aircraft parts are very strict. 2024 and 7075 are the most commonly used aluminum alloys in aircraft aluminum sheets.

Manufacturers use high-strength alloys (primarily Alloy 7075) to strengthen aluminum aircraft structures and other aerospace equipment. Aluminum alloy 7075 has copper (1.6%), magnesium (2.5%), and zinc (5.6%) added for ultimate strength, but the copper in it makes it difficult to weld. On the other hand, it’s anodized very nicely. 7075 has the best machinability, it produces a very nice finish.As a typical aircraft 4 x 8 aluminum sheet, 7075 aluminum sheet is a cold-worked forged alloy with high strength and high hardness, far superior to mild steel. 7075 aluminum sheet is one of the strongest commercial alloys with moderate corrosion resistance, good mechanical properties and anodic reaction. The fine grain makes the deep drilling performance better, the tool wear resistance is enhanced, the wire rolling is different from the weight, and the metal material with lower density requirements and higher hardness requirements is preferred. 7075 aluminum sheet is usually used to manufacture aircraft structures and other high-stress structural parts that require high strength and high corrosion resistance, such as aircraft upper and lower wings, stringers, partitions, etc. The 7075 aluminum plate for aircraft has good solid solubility after solution treatment, good heat treatment strengthening effect, high strength below 150°C, good low temperature strength, poor welding performance, and tendency to stress corrosion cracking. Double-stage aging can improve the resistance to stress corrosion cracking.
