Engineers, machinists, and fabricators working on load-bearing brackets, jigs, fixtures, and tooling plates need material that holds tight tolerances and resists deformation under stress. This listing offers a pack of 2 pieces of EN-AW 7075-T651 aluminium plate sheet, sized and ready for immediate use in demanding applications.\u003c\/p\u003e\n    \u003cp\u003eEach piece measures 10mm thick × 70mm wide × 160mm long (approx. 0.394″ × 2.756″ × 6.299″). The 7075-T651 designation indicates a zinc-based aluminium alloy in the artificially aged and stress-relieved condition, delivering one of the highest strength-to-weight ratios available in wrought aluminium. The T651 temper ensures residual stress has been relieved through controlled stretching, reducing the risk of warping during machining.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include CNC milling blanks for custom brackets and adapters, precision jig and fixture plates, aerospace-adjacent structural components, and prototype tooling where dimensional accuracy is critical.
