What Is 7049 Aluminum?<\/h2>\n

7049 aluminum is a high-strength 7xxx series alloy with high zinc and copper content, formulated primarily as a forging grade. It offers excellent resistance to stress-corrosion cracking and good machinability, which makes it a frequent choice for critical structural forgings in aerospace and missile applications. It is generally considered non-weldable and is best supplied as forged or machined parts. Linsy supplies 7049 in plate, bar, and forging stock with mill test certificates on every order.<\/p>\n

        7049 Aluminum FAQ<\/h2>\n

        Is 7049 weldable?<\/h3>\n

        No, 7049 is generally considered non-weldable and is supplied as forged or machined components.<\/p>\n

        Which temper resists stress corrosion best?<\/h3>\n

        The overaged T73 and T7451 tempers give the best resistance to stress-corrosion cracking; use them for critical aerospace structures.<\/p>\n

        Why are some mechanical values marked with an asterisk?<\/h3>\n

        The source mechanical data for 7049 was partially corrupted. Values shown are typical and must be verified against the mill certificate before release.<\/p>\n
