What Is 7050 Aluminum?<\/h2>\n

7050 aluminum is a high-strength 7xxx series alloy built around zinc, magnesium, and copper, with zirconium for grain control. It is closely related to 7075 but performs better in thick sections because it is less sensitive to quench rate, so strength is retained deeper into the plate. The T7451 temper gives strong resistance to exfoliation and stress-corrosion cracking, which is why 7050 is a workhorse for aerospace structures such as bulkheads, fuselage frames, and wing skins. Linsy supplies 7050 in plate, tube, and bar with mill test certificates on every order.<\/p>\n

    Strength retained in thick sections<\/h3>\n

    Less quench-sensitive than 7075, so plate stays strong through its depth.<\/p>\n

        7050 Aluminum FAQ<\/h2>\n

        How is 7050 different from 7075?<\/h3>\n

        7050 is less sensitive to quench rate, so it keeps strength better in thick plate, and its overaged tempers resist stress corrosion far better than 7075-T6.<\/p>\n

        Which temper should I use?<\/h3>\n

        T7451 is the standard for aerospace plate where corrosion resistance matters; T73510\/T73511 for extruded sections.<\/p>\n

        Is 7050 weldable?<\/h3>\n

        No, it is not a welding grade. Plan for machined or bonded assemblies.<\/p>\n

        What documents come with the order?<\/h3>\n

        Chaque commande est exp\u00e9di\u00e9e avec un MTC, et des rapports d'essais tiers SGS sont disponibles sur demande.<\/p>\n
