Aluminum Sheet Thk:1-6mm for Robot Model DIY Lightweight Durable Aluminum Plate

For lightweight structural panels and covers, 1–2mm is typically sufficient. For load-bearing brackets or motor mounts that experience vibration, 3–5mm provides better rigidity. If your frame needs to resist bending under significant lateral force, 6mm is the stiffest option in this range. When in doubt, prototype with a thinner sheet first and step up if deflection is noticeable.

Yes. Aluminum taps cleanly with standard HSS taps and cutting fluid. For plates 3mm and thicker, M3 threads are reliable with full thread engagement. For thinner plates (1–2mm), consider using through-bolts with nuts or threaded inserts rather than tapped holes, as thread depth is limited.

The plates themselves are flat blanks without pre-drilled holes, so compatibility depends on your hole layout. You can drill mounting holes to match standard 20mm or 40mm extrusion slot spacing. The alloy is the same material family as most extrusion systems, so fasteners and brackets designed for aluminum will work correctly.

Aluminum does not rust. It forms a thin, stable aluminum oxide layer on exposure to air that acts as a natural barrier against further corrosion. For prolonged outdoor or marine exposure, anodizing or powder coating adds additional protection, but for typical RC and robotics use the bare mill finish is adequate.

Thin plates (1–2mm) can be scored and snapped or cut with aviation snips. Plates 3mm and above are best cut with a jigsaw fitted with a metal-cutting blade, a bandsaw, or a CNC router with an upcut spiral bit. Always use cutting fluid or lubricant to extend tool life and reduce burring. Deburr edges with a file or deburring tool after cutting.

Dimensions are listed as Width × Length × Thickness in millimeters. For example, 100×200×3mm means the plate is 100mm wide, 200mm long, and 3mm thick. If your design requires a specific orientation, either dimension can serve as the long axis since the plates are rectangular blanks without a fixed orientation.

Yes. The mill-finished surface accepts anodizing, powder coating, and spray paint after light sanding and degreasing. For anodizing, use a professional anodizing service or a DIY anodizing kit designed for aluminum. For paint, a self-etching primer formulated for bare metal improves adhesion significantly.
