Diameter Ø 58mm Aluminium Discs-Circles-Round Aluminum Sheet (0.3mm Thick)

Each disc measures Ø 58mm in diameter (approximately 2.28 inches) and 0.3mm in thickness (approximately 0.012 inches). These dimensions are consistent across all pieces in a pack.

Common uses include electronics shielding blanks, craft stamping discs, decorative medallion bases, lightweight gasket templates, speaker grille prototypes, and any application requiring a pre-cut circular aluminum blank at a fixed 58mm diameter.

At 0.3mm thickness, these discs are suited for light forming, hand stamping, and bending operations. They are not intended for structural or heavy-load applications. For deeper draws or high-force stamping, verify the alloy grade is appropriate for your process.

Aluminum naturally forms a thin oxide layer that provides good resistance to everyday corrosion. For outdoor or high-humidity environments, an additional anodizing or coating step is recommended to extend service life.

Choose 10pcs for prototyping or single-project use, 20pcs for small batch work or to keep a modest stock on hand, and 50pcs for repeat production runs or projects requiring multiple identical discs. Larger packs offer a lower per-piece cost.

Yes. At 0.3mm thickness, these discs can be drilled with standard HSS drill bits, cut with tin snips or a craft knife, and finished with fine-grit abrasive. Use light pressure and appropriate speeds to avoid tearing the thin material.

Aluminum sheet discs are generally compatible with anodizing, powder coating, and spray painting after proper surface preparation (degreasing and light sanding). Confirm the specific alloy grade before anodizing, as some alloys respond better than others.
