Machinists, fabricators, and serious DIYers who work with structural brackets, jigs, fixtures, and tooling plates need an alloy that delivers consistent hardness and tight dimensional tolerances right out of the box. This 4-piece set of EN-AW 7075-T651 aluminium plate sheet is built for exactly those demands.\u003c\/p\u003e\n    \u003cp\u003eEach plate is cut to 14mm thick × 60mm wide × 170mm long (approximately 0.55\" × 2.36\" × 6.69\") from EN-AW 7075 aluminium alloy in the T651 temper — a stress-relieved, solution heat-treated, and artificially aged condition that maximises hardness and minimises residual stress. The 7075 alloy is one of the strongest commercially available aluminium grades, with a zinc-dominant composition that delivers tensile strength typically in the range of 500–570 MPa.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include CNC machining blanks for custom brackets and adapters, precision jig and fixture plates in workshop setups, lightweight structural components in RC vehicles and drone frames, and prototype tooling for aerospace-adjacent DIY applications where strength-to-weight ratio is critical.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Suitable for milling, drilling, turning, and anodising.
