When your project demands a flat, burr-free metal blank that holds tight tolerances, generic sheet offcuts simply don't cut it. Makers, jewellers, electronics hobbyists, and hardware engineers who need repeatable round stock turn to H62 solid brass disc blanks — a reliable starting point that eliminates the time-consuming step of cutting circles from sheet stock.
Each disc is cut from H62 copper-zinc alloy brass sheet, offering a warm golden surface finish straight from the pack. Thickness options span 0.3 mm to 1.5 mm (approximately 0.012 in to 0.059 in), and diameters run from 10 mm to 300 mm (approximately 0.39 in to 11.81 in), covering a wide range of project scales. Discs are supplied flat with consistent edge quality across the range.
Typical applications include custom gaskets and shims for mechanical assemblies, decorative inlay blanks for woodworking and leathercraft, conductive contact pads in low-voltage electronics prototyping, and stamping or etching blanks for jewellery and nameplate production. The combination of machinability and corrosion resistance makes these discs a go-to raw material for brass disc blanks for jewellery making, custom shim stock brass round blanks, and DIY electronics brass sheet circles.

Thinner discs (0.3 mm – 0.5 mm) are ideal for flexible shims, decorative inlays, and lightweight jewellery blanks where minimal material is needed. Mid-range thicknesses (0.8 mm – 1 mm) suit gaskets, contact pads, and general fabrication. Thicker options (1.2 mm – 1.5 mm) are better for structural components, heavier stamping, or parts that need to hold a thread. Select your thickness from the "Thick X Diameter" variant dropdown above.
Measure the outer diameter of the mating surface or bore you need to seal or space, then select the next size up from our range (10 mm to 300 mm). You can trim or drill the blank to final size after delivery. For precision fits, we recommend ordering one size larger than your target OD to allow for finishing.
H62 brass is a copper-zinc alloy that is significantly harder and stiffer than pure copper, making it more resistant to deformation under load. It machines cleanly, holds drilled holes well, and resists wear better than soft copper. For applications requiring higher tensile strength, H62 is a practical choice over pure copper sheet.
H62 brass has inherent corrosion resistance in dry indoor environments. Like all brass, it will develop a natural patina (darkening or slight oxidation) when exposed to air and humidity over time. For applications requiring a bright finish, apply a clear lacquer or brass polish after use. For outdoor or high-humidity environments, consider a protective coating.
Yes. H62 brass solders readily with standard lead-free or leaded solder and flux. It accepts electroplating (gold, silver, nickel) with appropriate pre-treatment. Laser engraving and mechanical engraving both work well on the mill-finish surface. For stamping, ensure your press tonnage is appropriate for the disc thickness selected.
Yes — these are a popular choice for jewellery blanks, pendant bases, and stamping stock. The flat, consistent surface accepts stamps, punches, and engraving cleanly. Thinner gauges (0.3 mm – 0.8 mm) are easiest to form and dome; thicker gauges (1 mm – 1.5 mm) are better for rigid pendants or components that need to hold their shape.
Pack quantity varies by size and is shown in the "Quantitys" variant option: smaller diameters are available in packs of 4 or 2 pieces, while larger diameters are typically sold as 1 piece per pack. Check the variant selector above to confirm the quantity included for your chosen size before adding to cart.
