What Is 7020 Aluminum?<\/h2>\n

7020 aluminum is a medium-strength 7xxx series wrought alloy with zinc and magnesium as the main hardeners. It is valued for excellent weldability, good corrosion resistance, and strong fatigue performance, making it a common choice for welded transport and structural assemblies. Compared with 7075 it offers slightly lower peak strength but better fabrication behavior, especially in marine or humid service. Linsy supplies 7020 in sheet, plate, tube, bar, and wire with full mill certificates and a range of tempers for welding and structural use.<\/p>\n

        7020 Aluminum FAQ<\/h2>\n

        Why choose 7020 over 7075?<\/h3>\n

        7020 trades some peak strength for much better weldability and corrosion behavior, which matters for welded transport and marine structures.<\/p>\n

        What tempers are available?<\/h3>\n

        We supply O, T5, T6, and T651 across sheet, tube, bar, and wire. Tell us the fabrication route and we will advise a temper.<\/p>\n

        Can 7020 be anodized?<\/h3>\n

        Yes. Anodizing improves corrosion and wear resistance; note that the coating color on 7xxx alloys can vary, so confirm appearance expectations with us.<\/p>\n

        Is a mill certificate included?<\/h3>\n

        Yes, every order includes an MTC, and SGS third-party reports are available on request.<\/p>\n

        Custom aluminum orders typically ship in 10\u201360 days depending on alloy, temper, size, and quantity. Stock or standard sizes may be faster \u2014 ask our team.<\/p>\n

        Can I get a mill test certificate?<\/h3>\n

        Yes. Every order includes an MTC. SGS third-party test reports are available on request.<\/p>\n

        Do you offer machining and finishing?<\/h3>\n

        Yes. We provide CNC machining, laser cutting, welding, anodizing, polishing, and powder coating so parts can be delivered closer to finished form.<\/p>\n
