Engineers, machinists, and serious DIYers working on load-bearing fixtures, jigs, tooling plates, and structural components need a plate that holds tight tolerances and resists deformation — that's exactly where the EN-AW 7075-T651 aluminium plate delivers.\u003c\/p\u003e\n\u003cp\u003eThis listing is for one (1) aluminium plate sheet in EN-AW 7075 alloy, T651 temper, measuring 16mm thick (~0.63 in) × 140mm wide (~5.51 in) × 140mm long (~5.51 in). The 7075 alloy combines zinc as its primary alloying element with magnesium and copper, producing one of the strongest aluminum alloys available. The T651 temper indicates solution heat-treated, stress-relieved by stretching, and artificially aged — resulting in a flat, stable plate with minimal residual stress ideal for precision work.\u003c\/p\u003e\n\u003cp\u003eTypical applications include CNC machining blanks, mold and die components, aerospace structural parts, high-load mechanical fixtures, and custom tooling plates where the EN-AW 7075-T651 aluminium plate must maintain dimensional accuracy under stress.\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 CNC milling, drilling, turning, and EDM operations.
