Historical development of aluminum alloy

Alumina was electrolytically reduced to aluminum in the laboratory in 1808 and was used as a building material in the steeple of Washington Monument in the United States in 1884. Aluminum alloys with various metallic elements have been widely used in the construction industry In all aspects.

In 1908, Alcoa invented the electrician aluminum alloy 1050 and made the ACSR, pioneering the pioneer of high voltage long distance transmission.

In 1915, Alcoa invented the 2017 alloy and invented the 2024 alloy in 1933, allowing the rapid expansion of aluminum in aircraft applications. In 1933, Alcoa invented the 6061 alloy to create an extruder quench process that significantly expanded the range of extrusion profiles.

In 1943, Alcoa invented 6063 alloy and 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 deepening research on aluminum alloy materials, the high-strength aluminum alloy (2000, 7000 series) has achieved more than 80% of its structural quality due to its excellent comprehensive performance on commercial aircraft. Therefore, Generally valued. Aluminum alloy began to gradually be used in life, military, science and technology.
