    The trade-off is clear: 7075-T73 gives up ~12\u201315% of T6’s peak strength to deliver Excellent stress-corrosion cracking resistance, higher fracture toughness, and better damage tolerance \u2014 the right call whenever corrosion, cyclic load, or long service life decide the build, and the wrong call in dry, strength-critical roles where T6 or T651 wins. Choose T73 or T7351 when chloride or humidity is in the picture; choose T6 or T651 when the environment is controlled and peak strength or machining stability leads the decision.<\/p>\n\n\n\n

    At Linsy Al\u00fcminyum<\/strong>, we stock 7075-T73 in plate, sheet, bar, and tube, with T7351 and other 7075 tempers (T6, T651) available across forms. Every order ships with a Mill Test Certificate, and SGS composition, mechanical, and ultrasonic (thick-plate) reports are available on request. Our team reviews your drawing, flags SCC risk before you over-specify, and recommends T73 versus T7351 based on whether the part is machined. \u00c7izimi ve gereksinimleri g\u00f6nderin, size bir s\u0131n\u0131f uygunluk incelemesi ve teklif d\u00f6nd\u00fcrece\u011fiz.<\/strong><\/p>\n\n\n\n

    S\u0131k\u00e7a Sorulan Sorular<\/h2>\n\n\n\n

    Is 7075-T73 weaker than T6?<\/h3>\n\n\n\n

    Yes, by about 12\u201315% \u2014 UTS drops from ~572 to ~505 MPa and yield from ~503 to ~435 MPa. What you gain is SCC resistance (Excellent versus moderate), fracture toughness (~28\u201333 versus ~20\u201324 MPa\u00b7\u221am), and better damage tolerance, so for any corrosive or long-life part the lower strength is the right trade.<\/p>\n\n\n\n

    7075-T73 vs T7351: which should I choose?<\/h3>\n\n\n\n

    Both carry the same overaged corrosion resistance; T7351 adds a 1.5\u20133% stress-relief stretch. Choose T7351 when the part is CNC-machined from thick plate, because the stretch keeps it from warping as material is removed. Choose plain T73 when forming or finishing is light and machining stability is not the deciding factor.<\/p>\n\n\n\n

    Is 7075-T73 good for marine or outdoor use?<\/h3>\n\n\n\n

    Yes \u2014 it is the preferred 7075 temper for marine, offshore, and coastal service because of its Excellent SCC and exfoliation resistance in chloride. It still benefits from anodizing, Alodine, or paint in severe exposure, but unlike T6 it is specified specifically because coating alone cannot be trusted to carry the risk.<\/p>\n\n\n\n

    Does Linsy stock 7075-T73, and what is the lead time?<\/h3>\n\n\n\n

    Yes. Stock plate, sheet, bar, and tube ship from inventory; non-stock sizes and tempers (including T7351) run on custom production with a typical lead time of 10\u201360 days depending on alloy, dimensions, and processing.
