The history of aerospace aluminum development
- 2017-12-08 10:30 -
Aluminum alloy has a series of advantages of low density, high specific strength, good corrosion resistance and formability, low cost and so on. It has a wide range of applications and irreplaceable positions in the fields of aviation, aerospace, shipbuilding, nuclear industry and weaponry industry.In aviation, aluminum alloy is the main timber of aircraft body structure.
Aluminum alloy development and aviation development are inextricably linked. At the beginning of the 20th century, the crankcase of the A1-Cu-Mn cast aircraft engine was used on the Wright Brothers aircraft. 1906 A. Wilm discovered in AI-Cu-Mg alloy age hardening phenomenon, the aluminum alloy as the main structural material of the aircraft possible, then, aluminum alloy as the main structural material of the aircraft body boarded the stage of history.

By the early twentieth century to the mid-1950s, the demand for aircraft material properties was only required to have high static strength. This will reduce the structural weight of the aircraft while increasing the aircraft's payload and range, scientists have developed the 2014 aluminum and 2017 aluminum alloy. Then developed the 2024 aluminum alloy, to the 1930s, 2024 alloy has been widely used in the aircraft, the 60's, 7075 aluminum alloy is widely used in the aircraft.
The use of aluminum alloy in aircraft has undergone years of development. In the future, the development trend of aircraft is high speed, long life, safe and reliable, low structural weight coefficient, low cost and integrated stealth. In the future development of aluminum in the aircraft will also be more and more widely used.
