Aerospace aluminum alloys have the advantages of low density, excellent comprehensive properties and low cost. Usually the amount used in the transport machine is about 70%. The progress of aluminium alloy material technology is inseparable from the demand and development of transporters. Aluminum alloy manufacturers in the world often cooperate with large aircraft manufacturers to improve aluminium alloy materials and develop new materials.
Aerospace aluminum alloys have different applications in different parts of foreign aircraft at different times. Before the 1970s, the main applications were ordinary 2024 and 7075 alloys; after the 1970s, high purity alloys were developed, including 2124-T851, 2324-T39, 2224 T3511, 7475-T73, 7475-T76, 7050-T451, 7050-T7452, 7010-T74 and 7150-T61. Since the 1990s, the latest developed 2524-T3, 7150-t7511, 7055-t7751, 7055-T77511, 2197-T851 and 7085-t7452 have been used on the most advanced aircraft.
In order to meet the requirements of design modification of old aircraft and development of new aircraft for comprehensive performance of airframe aluminium material and multi-varieties, multi-specifications and multi-heat treatment status, Henan Chalco has launched a comprehensive study on 7075-T73, 7075-T76, 2024-T3, 7475-T73, 7475-T76, 7050-T74, 2124-T851, 2224-T3, 2324-T39, 7175-T74

In order to meet the practical requirements of aircraft manufacturing and the development needs of future aircraft, Henan Chalco has carried out high-purity research on 7A04, 2A70, 2A12, 2A06 alloys. At the same time, it has also carried out research on super-high strength 7A55 alloys and high corrosion resistance 6A60 aluminum alloys, as well as on T77 status materials.
