Alloy 7050 aluminum plate is now more commonly used in aerospace applications than 7075, especially in the thickness range of 50-150 mm, because it maintains strength in the thicker part. Alloy 7050 aluminum plate has two states. T7651 (AMS 4201) combines the highest strength, good exfoliation corrosion resistance and stress corrosion cracking resistance.
7050 T7451 aluminum plate (AMS 4050) provides better SCC resistance and excellent spalling resistance at slightly lower strength levels.

7050 aluminum alloy is one of the most widely used high-strength aluminum alloys with the best comprehensive properties. It has high strength, high stress corrosion cracking resistance and good fracture toughness. Its main varieties are thick plates, profiles and forgings. Today we mainly talk about 7050 thick plate. There are two main states of 7050 thick plate: t7651 and T7451.
7050 T7451 aluminum plate has the best anti stripping corrosion ability and better stress corrosion resistance than t7651, but its strength is slightly lower. At present, the short transverse properties of 7050 Alloy thick plate have been further improved.
Chalco Aluminum often produces 7050-T7451 (AMS 4050) and 7050-t7651 (AMS 4201) aluminum alloy plates. In addition, 7050-t74511 (AMS 4342) aluminum alloy bars are also available.
7050-T7451 aluminum plate alloy has better toughness, corrosion resistance and stress corrosion cracking resistance than 7075 alloy. Because of its lower quenching sensitivity than most other aerospace alloys, the 7050 has better strength properties than other high-strength alloys in the thicker part. In the heavier gauge thickness range, the machine is more consistent. With these features, the
7050-T7451 aluminum plate is an excellent choice for aerospace and aircraft industry applications, suitable for making bulkheads, fuselage frames, wing skins, etc
