Aluminum alloy research and development in the early days is mainly linked with the aviation industry, only nearly a hundred years of history, but the development of fast, the scope of use continues to expand, in the metal materials in its output after steel ranked second, in the non-ferrous metal materials in the first place. Aluminum alloy will have great development: the use of updated process methods, improve the original alloy, develop new alloys, give the update more perfect performance, expand the scope of use, increase the use of.
In 1908, the aluminum company of the United States invented electrical aluminum alloy 1050, and made steel core aluminum stranded wire, creating a pioneer of high-voltage remote power transmission.
In 1915, Alcoa invented the 2017 alloy and in 1933 the 2024 alloy, which made the application of aluminum in aircraft rapidly expand. In 1933, Alcoa invented 6061 alloy and then created the extrusion quenching process, which significantly expanded the application range of extruded profiles.
In 1943, the American aluminum company invented 6063 alloy and 7075 alloy, which opened a new era of high-strength aluminum alloy.
In 1965, Alcoa invented the A356 cast aluminum alloy, which is a classic cast aluminum alloy.
With the in-depth research on aluminum alloy materials, high-strength aluminum alloy (2000, 7000 series) has reached more than 80% of its structural quality in commercial aircraft with its excellent comprehensive performance, so it has been widely valued by the global aviation industry. Aluminum alloy began to be gradually used in life, military, science and technology.
