    • The assembly is fusion welded \u2014 6061 for general work, 2219 if a 2xxx is required.<\/strong><\/li>\n\n\n\n
    • The part sees marine, de-icing salt or permanent moisture without cladding or coating \u2014 5083 or 6061.<\/strong><\/li>\n\n\n\n
    • The design needs a guaranteed yield above 260 MPa, the highest band in the table \u2014 2024-T351.<\/strong><\/li>\n\n\n\n
    • The drawing calls for 2017-T6 \u2014 2024-T351 or 2014-T6, because the temper has no standard minimum here.<\/strong><\/li>\n\n\n\n
    • Color-critical anodized finish is a specification line \u2014 6061, or plan on paint.<\/strong><\/li>\n<\/ul>\n\n\n\n

      In practice it lands on rivets and fasteners, machined fittings, bushings, brake pistons, hinge pins, pulleys, camera and optical components, jigs and tooling plate, and legacy aerospace secondary structure where the drawing is already fixed.<\/p>\n\n\n\n

      What to Put on the Purchase Order<\/h2>\n\n\n\n

      Four lines decide whether the material you receive is the material you designed around.<\/p>\n\n\n\n

        \n
      1. Designation and standard.<\/strong> Write “2017 per ASTM B209” or “EN AW-2017A per EN 573-3”, not just “2017”. The designations carry different magnesium limits, and the standard decides which minimums apply.<\/li>\n\n\n\n
      2. Temper and stress condition.<\/strong> T4 or T451, stated explicitly. If the part is heavily machined from plate, T451 is the stress-relieved choice and the certificate should say so.<\/li>\n\n\n\n
      3. Thickness or diameter band.<\/strong> Give the actual dimension, because the minimum mechanical property follows the band, not the alloy name.<\/li>\n\n\n\n
      4. Certificate content.<\/strong> Require a mill test certificate reporting actual chemical analysis and actual mechanical results for the heat or lot, with magnesium as a number rather than a pass mark.<\/li>\n<\/ol>\n\n\n\n

        Z\u00e1v\u011br<\/h2>\n\n\n\n

        2017 aluminum earns its place on a narrow set of arguments: a machined or riveted part, a drawing that already names the grade, and a service environment where the copper penalty is controlled by coating or by staying indoors. Everything it offers comes from copper, and so does everything it costs \u2014 corrosion resistance, weldability and color-consistent anodizing all fall away in exchange for naturally aged strength at a lower price than 2024.<\/p>\n\n\n\n

        We supply 2017 and 2017A plate, sheet, bar and tube in T4, T451 and O, cut to size or to drawing, with an MTC reporting actual chemistry and mechanical results so the magnesium figure is visible before you release the part.<\/p>\n\n\n\n

        Send us the drawing, the designation on it and the thickness you need, and we will confirm which specification and temper band the part falls into.<\/p>\n\n\n\n

        \u010casto kladen\u00e9 ot\u00e1zky<\/h2>\n\n\n\n

        Which designation belongs on the purchase order \u2014 2017 or 2017A?<\/h3>\n\n\n\n

        Use the designation on the drawing, then require the certificate to show actual magnesium. If the drawing is silent, 2017A is the wider specification and accepts both.<\/p>\n\n\n\n

        Is 2017 worth it over 6061 for a machined bracket?<\/h3>\n\n\n\n

        Only if you need more than 6061-T6’s guaranteed tensile floor \u2014 290 MPa minimum for sheet and plate. On typical values the two are level at about 276 MPa yield, and 6061 is cheaper to finish and easier to weld. Under that floor, 6061 wins; over it, 2017 is cheaper than 2024.<\/p>\n\n\n\n

        What is your MOQ and lead time for 2017 plate?<\/h3>\n\n\n\n

        Plate in T4 and T451 quotes at low minimums, with MOQ set against the thickness and size you need rather than a mill tonnage. Stock covers common thicknesses; non-standard sizes are produced to order on the same low-MOQ basis. Custom production runs 10\u201360 days depending on thickness, size and whether stress-relieved T451 is required.<\/p>\n\n\n\n

        Can you cut 2017 plate to size and supply the certificate with it?<\/h3>\n\n\n\n

        Yes \u2014 cutting plate and bar to length or to drawing is part of normal order processing, not a separate service. Every order leaves with a mill certificate we issue after production, listing actual chemical analysis and mechanical results for the lot. Where the drawing calls for third-party verification, SGS reports are available on request at additional cost.<\/p>","protected":false},"excerpt":{"rendered":"
