5052/6061-T6 Aluminum Round Sheets/Discs - Diameters: 50-300mm, Thick: 0.5-20mm

Choose 5052 if your project involves bending, forming, or exposure to moisture and salt air — it is softer and more ductile. Choose 6061-T6 if you need to machine threads, mill pockets, or carry structural loads — it is harder, stronger, and machines to a cleaner finish.

Discs are cut to close diameter tolerances suitable for most workshop and fabrication tasks. If your application requires certified dimensional tolerances (e.g., aerospace or precision instrument work), please contact us to confirm before ordering.

The discs are cut from flat sheet stock and are suitable as starting blanks for most machining operations. A light facing pass is recommended for applications requiring surface flatness better than approximately 0.1 mm across the face.

Yes. Both 5052 and 6061-T6 respond well to anodizing and powder coating. 6061-T6 in particular produces a consistent, hard anodized layer. Ensure all machining oils and coolants are thoroughly cleaned before sending parts for finishing.

Thin discs (0.5 mm – 2 mm) are suited for decorative face plates, gaskets, and shim stock. Mid-range thicknesses (3 mm – 8 mm) work well for speaker mounting rings, brackets, and light structural parts. Thicker discs (10 mm – 20 mm) are appropriate for turned pulleys, flanges, and load-bearing spacers. If you are unsure, contact us with your load and dimensional requirements.

Cut edges may have minor burrs depending on the cutting method. We recommend deburring with a file or deburring tool before handling in bare hands or assembling into finished products. Light sanding with 220-grit paper is sufficient for most applications.

The listed variants cover the most commonly requested sizes. For custom dimensions outside the available options, please contact us to confirm feasibility and lead time before placing an order.
