The use of industrial aluminum profiles in aerospace
Aluminum alloys processed by Shanghai Aluminum Profile CNC have a wide range of application prospects in aerospace components. For example, high-strength aluminum alloy thick plates are used as the main load-bearing components, accounting for 30% to 35% of the total aluminum used in aircraft. At present, the aluminum alloy materials used in civil aviation aircraft mainly include: aluminum alloy castings, aluminum alloy forgings, large-section Shanghai aluminum profiles, aluminum alloy thick plates, etc. Among the materials used in my country's regional passenger aircraft ARJ21-700 and C919 large passenger aircraft with independent intellectual property rights, the mass of Shanghai extruded aluminum and aluminum alloy parts accounts for 65% to 75% of the total mass of the aircraft. Extruded profiles and plates made of high-strength aluminum alloys account for 30%-35% of the total aluminum used in aircraft.
According to the plan, more than 30% of aluminum alloy materials used in ARJ21 regional airliner and C919 large aircraft will be domestic aluminum by 2018. At present, the proportion of domestic materials used in my country's large aircraft C919 is only 5% to 6%. In the next few years, the investment ratio of aluminum alloy in the aircraft market will see a qualitative improvement.
The analysis predicts that the global air passenger volume will grow at an average annual rate of 4.7% between 2014 and 2023, with 19,000 new passenger and cargo aircraft added, about 12,400 low-fuel aircraft to be retired and replaced by new aircraft, and the global market demand for new wide-body passenger and cargo aircraft to reach about 9,300, accounting for 30% of the total number of new aircraft in the same period. The number of aircraft worldwide is expected to increase by 1%, of which Asia will increase by 35%.
According to the forecast of my country Aviation Industry Corporation, by 2025, my country's air transport aircraft will reach 3,900, including 2,000 large passenger aircraft.
my country's aviation manufacturing industry has entered a period of rapid development. The production of private aircraft, civil aviation and large aircraft is increasing year by year. The market scale of aviation aluminum will become larger and larger in recent years.
