Aviation materials are the foundation for the development of the aviation industry and involve a large amount of global import and export trade. Due to the high demand for materials by aerospace parts manufacturers, the aerospace materials market in Asia-Pacific, Europe and North America has huge potential.
The aviation material including aircraft aluminum sheet are important technical guarantees for realizing advanced aircraft with high performance, light weight, high reliability, long life, and low cost. Based on the importance of aircraft materials,the world's aviation powers attach great importance to the development of aircraft materials.
At present, China has basically formed a relatively complete aviation material research and development technology system and mass production capacity, and has the ability to supply key materials for major aviation equipment. There are some typical ones.
2024 Aluminum Sheet
2024 T3 aluminum sheet is the most common high-strength aluminum alloy. 2024-T3 aluminum plate is of super high strength and excellent fatigue resistance. Welding is generally not recommended. The typical use is for fuselage, wing shells and aircraft structure.
6061 T6 Aluminum
It has very good corrosion resistance and finishing ability, and good welding performance. The strength level of 6061-T6 aluminum plate is equivalent to that of low carbon steel. Its typical uses are aircraft landing pads, truck bodies and frames, structural parts, etc.
7075 Aluminum Alloy
Aircraft manufacturers use high-strength alloys, 7075 aluminum alloy to strengthen aluminum aircraft structures. 7075 aluminum sheet belong to Al-Zn-Mg-Cu alloy for ultimate strength, but the copper content makes it very difficult to weld. On the other hand, it has good anodizing effect. Aluminum 7075 has the best machining performance and can achieve very good results.
