Aluminium Alloy Metal Plate Thick 10mm Aluminum Board Sheet 100x100mm~150x200mm

Select the size closest to your finished part dimensions, leaving a small margin for machining or trimming. For example, if your finished bracket is 90×140mm, the 100×150mm plate gives you approximately 5mm of working margin on each edge. Avoid over-sizing significantly, as you'll pay for material you'll cut away.

Aluminum alloy at 10mm thickness provides solid rigidity for brackets, spacers, and light structural gussets. It is approximately one-third the weight of equivalent steel plate but also lower in tensile strength. For applications requiring high load-bearing capacity, consult an engineer. For typical DIY mounting plates and enclosure panels, 10mm aluminum alloy is more than adequate.

Aluminum alloy naturally forms a thin, stable oxide layer that protects against rust. These plates are suitable for sheltered outdoor use (e.g., under an awning or inside an enclosure). For prolonged direct exposure to salt spray or harsh chemicals, consider applying an anodizing treatment or protective coating after machining.

Yes. Aluminum alloy machines readily with standard HSS (high-speed steel) or carbide drill bits. Use cutting fluid or light oil to extend tool life and achieve cleaner holes. For tapping threads, aluminum alloy accepts standard metric and imperial taps well — use a spiral-flute tap for through-holes and a bottoming tap for blind holes.

Each product listing covers one size combination (Width × Length) and one packing quantity. To order multiple different sizes, add each size variant to your cart separately. The Packing Quantity option (1, 2, 3, or 5 pcs) applies to identical pieces of the selected size.

If you're prototyping a single part, the 1 Pcs option minimizes upfront cost. If you're building multiple identical assemblies, need spares for future repairs, or want matched blanks for batch machining, the 2, 3, or 5 Pcs packs typically offer a lower per-piece cost. Check the per-unit price across pack sizes before selecting.

For straight cuts, a metal-cutting band saw or circular saw with an aluminum-rated blade works well. For curved or complex profiles, a jigsaw with a fine-tooth metal blade or a CNC router with an upcut spiral bit is recommended. Always wear eye protection and use appropriate cutting speeds — aluminum cuts best at higher RPM with light feed pressure.
