Aluminum Alloy Material History
Aluminum Alloy is the most widely used Non-ferrous metal structural material in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing day by day, which makes the research on the weld ability of aluminum alloy go deep into. At present, aluminum alloy is the most widely used alloy.
Chinese name： Aluminum Alloy
Category ： Non-ferrous Metal
Melting Point ： 660 °C
Specific gravity ： 2.702
Alumina was reduced to aluminium in the laboratory at the 1808 and has been used as a building material in the American Washington Monument since 1884; Aluminum Alloy material which is synthesized by adding various metal elements has been widely used in building industry.
In 1908 Alcoa invented electric aluminum alloy 1050, and made into a Aluminium conductor steel-reinforced cable, pioneering high-voltage long-distance transmission.
The invention of alloy 2017 in 1915 and of Alloy 2024 in 1933 rapidly expanded the use of aluminum in aircraft In 1933, Alcoa invented the 6061 alloy, then created the extrusion quenching process, significantly expanding the application of extrusion profiles.
In 1943, Alcoa invented the 6063 alloy and the 7075 alloy, ushering in a new era of high strength aluminum alloy.
In 1965 Alcoa invented the A356 cast aluminum alloy, this is the classic casting aluminum alloy.
With the further research on the aluminum alloy materials, the high-strength Aluminum Alloys (series 2000,7000) have been used in the commercial aircraft with excellent comprehensive performance, which has reached more than 80% of its structural quality Therefore, the global aviation industry has received widespread attention. Aluminum Alloy began to gradually applied to life, military, scientific and technological aspects.
we are singing, we are dancing. happy new year to you all.
