The 7150 is the second generation modification of 7050 Alloy, the main varieties have thick plates and profiles, the use of the state of T7751 and T77511. Compared with other 7 * * * * system alloys, 7150 T77 alloys have obtained the best combination of strength and corrosion properties.
The 7150 alloy is mainly supplied in the form of T7751 thick plate, 7150 aircraft aerospace grade aluminum plate sheet is used for the main stress parts of the upper wing structure and aircraft structure, such as wing upper wall panels, beams, edge strips and so on.
