Alumina was reduced to aluminum by electrolysis in the laboratory in 1808. It was used as a building material in the United States on the spire of the Washington Monument in 1884. Aluminum alloys with various metal elements have been widely used in the construction industry. In all aspects.
In 1908, Alcoa invented the electrician aluminum alloy 1050 and made it into a steel core aluminum stranded wire to create a pioneer in high-voltage remote transmission.
In 1915, Alcoa invented the 2017 alloy and invented the 2024 alloy in 1933, which enabled the rapid expansion of aluminum in aircraft applications. In 1933, Alcoa invented the 6061 alloy, which immediately created an extruder quenching process that significantly expanded the range of extrusion profiles.
In 1943, Alcoa invented the 6063 alloy and the 7075 alloy, creating 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 deep research on aluminum alloy materials, high-strength aluminum alloys (2000, 7000 series) have achieved more than 80% of their structural quality with their excellent comprehensive performance on commercial aircraft, so they have been awarded by the global aviation industry. Generally attached. Aluminum alloys began to be applied to life, military, and technology.
