7050 Aluminum Round Bar
7050 aluminum round bar is a premium, high-strength aluminum alloy developed specifically for aerospace and high-performance engineering applications where a combination of high strength, fracture toughness, and resistance to stress corrosion cracking (SCC) is crucial. Belonging to the 7000 series, 7050 is characterized by a carefully balanced composition of zinc, magnesium, and copper, offering superior mechanical properties in thicker sections compared to earlier 7000 series alloys such as 7075.
The most commonly used temper for 7050 round bars is T7451, a stress-relieved temper that provides high strength with improved resistance to stress corrosion and exfoliation corrosion. This makes it particularly suited for thick plate, forged sections, and precision round bars used in airframe structures, bulkheads, wing roots, and other critical load paths where failure is not an option.
