7150-T77 aluminum plate is a heat treatable wrought alloy, which meets the requirements of corrosion performance without sacrificing the strength of the alloy. It is used in the aerospace industry for manufacturing aircraft components. Heat treatment can improve its anti-corrosion properties with a low corresponding decrease in strength.

2024, 7075, 7475, 7150 and 7055 aluminum alloy are typical aircraft aluminum plates, featuring low density, high specific strength, good corrosion resistance and excellent formability, which is used for fuselage skins, wing and stabilizer skins, fuselage bulkheads, fuel tanks, connectors and other structures.
Through the application of aluminum alloy, the aircraft weight can be reduced by 10%, thereby improving fuel efficiency. Due to the aircraft aluminum’s good fatigue resistance and damage tolerance, the inspection period can be extended and the maintenance cost of the spacecraft can be reduced.
