2-series and 7-series aerospace aluminium for sale Haomei

Aluminium for aviation is mainly deformed aluminium, with castings accounting for a relatively low proportion. On average, flat rolled aluminium accounts for 60%, extruded aluminium (tubes, bars, shapes, wires) for 28%, forgings for 7% and castings for 5% of the aluminium consumed in aircraft. According to the classification of alloy composition, aluminium for aviation is mainly 2-series and 7-series. Today, the world's large aircraft structure with aluminium alloy is mainly high-strength 2 series of aviation aluminum (2024, 2224, 2324, 2424, 2524, etc.) and ultra-high strength 7 series of aviation aluminum (7075, 7475, 7050, 7150, 7055, 7085, etc.), in the civilian passenger aircraft aluminum accounted for about 38%, 45%, respectively.

One generation of aircraft, one generation of materials, aluminium for aviation has developed to the third generation of aluminium alloy materials represented by aluminium-lithium alloy. There are three stages in the development of aluminium for aviation: the first stage is 1930s-1960s, 2-series aluminium alloy makes all-metal aircraft become mainstream, while 7-series aluminium alloy represented by early 7075 makes it possible for passenger aircraft to fly in the stratosphere, the representative models are DC-3, B-29 and 70; the second stage is 1960s-1990s, 7050 and 7055 and a series of new 7 The third stage is from 2000 to the present, under the competition of composite materials, the third generation aluminium alloys represented by aluminium-lithium alloys have been adopted by more and more new aircraft types, including A220, China's C919, etc. The representative grades are 2050 and 2196 from Kenland and 2099 and 2399 from Alcoa. In addition to aluminium-lithium alloys, aluminium-based composites and superplastic forming aluminium alloys are also key research directions for aviation aluminium.
