7000 series aluminum alloy has been the first choice for aerospace and aircraft applications since the commercial aircraft manufacturing was launched in the post World War II era. The 7xxx series provides designers with extremely high strength, low manufacturing cost and low replacement risk, and is the preferred alloy in applications with strength as the main requirement.
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 temper.
7050 T7651 aluminum plate (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。
Henan Chalco has stocks of 7050-T7451 aluminum plate (AMS 4050) and
7050-t7651 aluminum plate (AMS 4201). 7050-t74511 (AMS 4342) aluminum alloy bars are also available. 7050-T7451 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-T7651 aluminum plate is an excellent choice for aerospace and aircraft industry applications, suitable for making bulkheads, fuselage frames, wing skins, etc.
