4pcs Aluminium Plate Sheet EN-AW 7075 T651 Grade 14mm Thick 60mm Wide 170mm Long

7075-T651 is significantly harder and stronger than 6061-T6, with tensile strength typically 30–40% higher. It machines cleanly and holds tighter tolerances, making it the preferred choice for structural jigs, fixtures, and load-bearing brackets. However, 6061 is easier to weld and offers better corrosion resistance without coating, so choose 7075 when strength is the priority.

T651 means the plate has been solution heat-treated, stress-relieved by stretching, and then artificially aged. The stretching step removes internal residual stresses that would otherwise cause the plate to warp or distort during machining. This makes T651 the preferred temper for precision machining applications where dimensional stability is critical.

7075 has moderate corrosion resistance due to its natural oxide layer, but it is less corrosion-resistant than 6061 or 5052 in aggressive environments. For outdoor, marine, or high-humidity applications, anodising or applying a chromate conversion coating (e.g. Alodine) is strongly recommended to protect the surface.

Welding 7075 aluminium is technically possible but not recommended for structural applications without specialist knowledge. The high zinc content makes it susceptible to hot cracking during fusion welding. If joining is required, mechanical fastening (bolts, rivets) or adhesive bonding is generally preferred. Consult a welding specialist if welding is unavoidable.

Standard carbide end mills work well with 7075-T651. For a 14mm-thick plate, use a 2- or 3-flute carbide end mill with a cutting depth of no more than 1× the tool diameter per pass. HSS tooling can also be used at lower feed rates. Use cutting fluid or compressed air to manage chip evacuation and heat, especially for deep pockets.

These plates measure 14mm thick × 60mm wide × 170mm long. They are well-suited for small structural brackets, adapter plates, jig components, and prototype parts where a compact, thick billet is needed. If your part requires larger dimensions, check our other aluminium plate listings or contact us to confirm availability of custom sizes.

Yes. 7075 aluminium anodises well and accepts both Type II (decorative/protective) and Type III (hard anodise) finishes. Anodising after machining is a common workflow — machine your part to final dimensions first, then send to an anodising service. Note that hard anodising adds approximately 0.025–0.05mm per surface, so account for this in your tolerances if tight fits are required.
