What is 7050 Aluminum Alloy?
7050 aluminum alloy is a high-strength, heat-treatable aluminum alloy with excellent exfoliation corrosion resistance, stress corrosion cracking (SCC) resistance, and good toughness, making it widely used in the aerospace industry. Compared to other 7000 series alloys such as 7075, 7050 has lower quench sensitivity, allowing it to maintain excellent strength characteristics in thicker sections and exhibit better corrosion resistance, especially in thicknesses ranging from 3 to 6 inches.
7050 aluminum alloy is typically used in aerospace structural components such as fuselage frames, bulkheads, and wing skins. Its corrosion resistance and exfoliation resistance are superior to those of 7075 aluminum alloy, especially in thicker plates. The 7050 T7451 aluminum plate (AMS 4050) maintains high strength while demonstrating excellent SCC and exfoliation corrosion resistance. In contrast, 7050 T7651 (AMS 4342) has slightly higher strength but its SCC resistance is somewhat inferior to T7451.
The primary alloying elements in 7050 aluminum are zinc and magnesium. By increasing the magnesium content, the tensile strength, stress corrosion resistance, and exfoliation corrosion resistance are significantly improved. After heat treatment, 7050 alloy exhibits a much stronger effect than binary aluminum-zinc alloys, making it widely used in high-strength, corrosion-resistant aerospace structures, particularly in high-stress aircraft components.
With its low quench sensitivity and sustained strength, 7050 aluminum alloy is the material of choice in the aerospace field, especially for large structures that require extremely high strength and corrosion resistance, such as fuselage frames, bulkheads, and wing skins. 7050 T7451 aluminum alloy, with its exceptional performance, is widely used in critical aircraft components that demand low maintenance and optimal strength.
