Finding flat, dimensionally consistent brass disc blanks that don't require hours of finishing work is a genuine challenge for jewellers, machinists, and makers. These H62 brass disc blanks are cut to size and ready to use straight from the pack — no warping, no rough edges — making them the go-to choice for hobbyists and trade buyers who need reliable raw stock on demand.
Each disc is made from H62 solid brass alloy, offering a copper-zinc composition that balances workability with structural integrity. Diameters range from 50 mm (approx. 2 in) to 200 mm (approx. 7.9 in), and thickness options span 0.8 mm to 3.0 mm (approx. 0.031 in to 0.118 in). Discs are supplied in flat, unfinished condition with smooth sheared edges suitable for further machining, stamping, or surface treatment.
Typical applications include custom jewellery blanks and pendant bases, clock face and dial fabrication, gasket and shim stock for light engineering, decorative inlay and craft projects requiring brass round sheet stock, and prototyping components where a machinable non-ferrous metal is specified.
Made from H62 copper-zinc brass, offering good machinability, corrosion resistance, and a warm golden appearance that polishes to a bright finish.
Available in diameters from 50 mm to 200 mm and thickness from 0.8 mm to 3.0 mm — choose the exact combination that matches your project spec.
Discs are shear-cut and supplied flat, minimising finishing time and making them ready for immediate stamping, engraving, or machining operations.
Order from single pieces up to packs of 30, so you can trial a size before committing to bulk stock or top up exactly what you need.
H62 brass responds well to drilling, turning, filing, and soldering — suitable for both hand-tool and machine-tool workflows without specialist equipment.
The natural brass oxide layer provides baseline corrosion resistance for indoor and light outdoor applications; apply lacquer or plating for extended protection.

For jewellery pendants and light stamping, 0.8 mm – 1.0 mm is typically sufficient. For structural components, gaskets, or parts that will be machined on a lathe, 1.5 mm – 3.0 mm provides better rigidity and more material to work with. If you are unsure, order a small quantity of two thicknesses to test before committing to a larger pack.
The discs are shear-cut with burr-reduced edges, so they are generally safe to handle with care. For applications where a completely smooth edge is required — such as wearable jewellery — a light pass with a fine file or deburring tool is recommended before use.
H62 brass naturally develops a patina over time when exposed to air and moisture. For indoor decorative use this is often desirable. To maintain a bright finish, apply a clear lacquer or brass polish after any surface work. For outdoor or high-humidity environments, consider electroplating or a protective coating.
Yes. H62 brass solders and brazes well using standard silver solder, soft solder, or brass brazing rod. Clean the surface with flux before joining to ensure a strong bond. The material is also compatible with TIG and MIG welding using appropriate brass filler wire.
H62 brass machines cleanly on CNC lathes and mills. For laser cutting, brass reflects CO₂ laser wavelengths, so a fibre laser is recommended for clean cuts. The flat, consistent thickness makes fixturing straightforward for both CNC routing and stamping press operations.
Single-piece listings are ideal for prototyping or one-off projects. Multi-pack options (up to 30 pieces) offer a lower per-unit cost and are suited to production runs, classroom use, or stocking a workshop. All pieces within a pack are the same thickness and diameter as selected.
Yes — brass disc blanks are a traditional choice for clock dials, instrument faces, and decorative plaques. The 0.8 mm and 1.0 mm thicknesses are popular for engraved or etched dial work, while 1.5 mm – 2.0 mm suits heavier decorative applications. The flat surface accepts chemical etching, engraving, and printed transfers.
