Aluminum alloy has a series of advantages such as low density, high specific strength, good corrosion resistance and excellent formability. These excellent properties make aluminum alloy an important material for aerospace. Mainly used for fuselage skins, wings and stabilizer skins, fuselage bulkheads, fuel tanks, connectors and other structures.
Through the application of aluminum alloy composite materials, the shell material on aerospace vehicles can reduce the density by 5%-7%, increase the material stiffness by 7%, and reduce the weight by 10%, thereby improving fuel efficiency. Corrosion and good fatigue resistance and damage tolerance, extend the time between inspections, and reduce the maintenance cost of the spacecraft.
Lower capital cost: Aluminum alloy has a certain price advantage over steel.
Typical alloys such as: 2024, 7075, 7475, 7050, 7150, etc.
