Round 6061 Aluminum Sheet Disc Plate 1mm-20mm Thick DIY Model Craft Art Handmade

6061 (typically T6 temper) is harder, stronger, and machines more cleanly — it's the better choice when you need to drill, mill, or tap threads. 5052 (typically H32 temper) is softer and more ductile, making it easier to bend or form without cracking, and it offers slightly better corrosion resistance in marine or humid environments. For flat, unformed disc applications, either alloy works well; choose 6061 for machining and 5052 for forming or coastal use.

Start with your required outer dimension and add any machining allowance (typically 1–2mm per side for turning or edge cleanup). For thickness, consider the load or rigidity requirement: 1–2mm discs are suitable for decorative or lightweight applications; 3–6mm for structural backing plates or moderate load-bearing; 8mm and above for heavy-duty or high-rigidity applications. If you're unsure, contact us to confirm before ordering.

No — these are solid, undrilled round blanks. There are no pre-drilled holes, center bores, or cutouts. You drill, punch, or machine any holes required for your specific application. This gives you full control over hole placement, size, and pattern.

Yes. Both 6061 and 5052 alloys are compatible with standard anodizing processes, which improves surface hardness and corrosion resistance while allowing color dyeing. They can also be primed and painted using aluminum-compatible primers. For best adhesion, clean and degrease the surface before any coating process. Note that the discs are supplied in raw mill finish — no pre-treatment is applied.

These are cut-to-size raw stock discs. Typical dimensional tolerances for cut aluminum sheet are ±0.1–0.5mm on diameter and ±0.1–0.2mm on thickness, depending on the size. If your application requires tighter tolerances, plan for a finish-machining step (turning the OD or facing the surfaces) after receiving the blanks. Contact us to confirm tolerances for specific sizes if needed.

For one-off or prototype projects, the 1 Pc or 2 Pcs packs let you test fit and function before committing to more material. For small production runs or workshop stock, the 5 Pcs, 10 Pcs, or 25 Pcs packs offer a lower per-piece cost and reduce reorder frequency. Select the quantity that matches your expected usage to avoid excess inventory.

Aluminum naturally forms a protective oxide layer that resists rust and general corrosion in most outdoor and moderate-humidity environments. For prolonged exposure to saltwater, chemicals, or highly acidic conditions, 5052 alloy offers better corrosion resistance than 6061. For extended outdoor use, applying an anodized finish or aluminum-compatible sealant will further extend service life.
