These aluminum sheet plates are stocked in nine size-and-thickness combinations — from a compact 100×100×3mm (3.94″×3.94″×0.12″) up to a broad 150×200×6mm (5.91″×7.87″×0.24″) — so hobbyists, students, and small-shop fabricators can pick exactly the blank they need without cutting down oversized stock.\u003c\/p\u003e\n\u003cp\u003eEach plate is cut from aluminum alloy with a smooth, mill-finished surface. Dimensions follow the format Width × Length × Thickness (mm), with thickness spanning 1–6mm across the range. The alloy composition is consistent with common structural aluminum grades, offering a balance of low weight and adequate stiffness for panel and bracket applications.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include robot model structural frames, drone and RC car chassis reinforcement panels, electronics enclosure lids, CNC practice blanks, and lightweight shelf brackets in workshop jigs. The flat, burr-free surface accepts drilling, tapping, anodizing, and powder coating without pre-treatment.\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 Fits standard M3–M5 bolt patterns.
