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

Gids voor het kiezen van de juiste temperatuur<\/h2>\n
    \n
  • O<\/strong> \u2014 Gegloeid, zachtste conditie voor vervormen.<\/li>\n
  • T5<\/strong> \u2014 Cooled from hot working and artificially aged; good strength with simpler processing.<\/li>\n
  • T6<\/strong> \u2014 Solution heat-treated and artificially aged; prime structural temper.<\/li>\n
  • T651<\/strong> \u2014 Stress-relieved T6 for machining stability.<\/li>\n<\/ul>\n

    Belangrijkste kenmerken<\/h2>\n

      Opmerkingen over bewerking en oppervlakteafwerking<\/h2>\n

      Linsy cuts 7020 with laser and machines it on CNC centers. It welds well with MIG\/TIG using matching or compatible fillers; post-weld aging can recover properties. Anodizing or powder coating improves surface durability.<\/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

        Veelgestelde vragen over bestellingen in het algemeen<\/h2>\n

        Wat is de gebruikelijke levertijd?<\/h3>\n

        Op maat gemaakte aluminiumbestellingen worden doorgaans verzonden binnen 10\u201360 dagen, afhankelijk van legering, conditie, maat en hoeveelheid. Voorraad of standaardmaten kunnen sneller zijn \u2014 vraag ons team.<\/p>\n

        Kan ik een fabriekstestcertificaat krijgen?<\/h3>\n

        Ja. Elke bestelling bevat een MTC. SGS-testrapporten van derden zijn op verzoek beschikbaar.<\/p>\n

        Bieden jullie bewerking en afwerking?<\/h3>\n

        Ja. Wij bieden CNC-bewerking, lasersnijden, lassen, anodiseren, polijsten en poedercoaten, zodat onderdelen dichter bij de afgewerkte vorm kunnen worden geleverd.<\/p>\n
