When your project demands a flat, true-round metal blank that machines cleanly and holds a polished finish, generic sheet offcuts just don't cut it. Whether you're a hobbyist machinist, a jewellery maker, or a small-workshop fabricator, sourcing the right H62 brass solid disc blank in the exact thickness and diameter you need can eat up hours. These ready-to-use round discs eliminate that frustration and let you get straight to work.
Each disc is cut from H62 brass alloy — a copper-zinc composition (approximately 62% copper) known for its balance of machinability, corrosion resistance, and warm golden appearance. Available in two thicknesses, 5mm (~0.197 in) and 6mm (~0.236 in), with outer diameters ranging from 10mm (~0.39 in) up to 200mm (~7.87 in), these blanks cover a wide spectrum of project scales. Edges are typically smooth-cut; minor burr removal may be needed on larger diameters.
Typical use cases include custom engraving medallions and name tags, lathe-turned knobs and spacers for workshop equipment, decorative inlays and hardware accents in furniture making, and electrical contact blanks or heat-sink shims in light electronics projects — all applications where a reliable H62 brass round disc blank delivers consistent results.
Approximately 62% copper content delivers a reliable balance of machinability, ductility, and a warm golden tone that takes polishing and engraving well.
OD from 10mm to 200mm (0.39–7.87 in) in 5mm and 6mm thicknesses — one listing covers dozens of project sizes without custom cutting orders.
Supplied as solid round discs with no pre-drilled holes, giving you a clean starting point for turning, drilling, milling, or engraving to your exact spec.
H62 brass naturally resists oxidation in typical indoor and light outdoor environments, making it suitable for decorative hardware, marine accents, and instrument parts.
Each disc is cut to a nominal 5mm or 6mm thickness, providing predictable stock removal and reliable fit when used as spacers, shims, or inlay blanks.
Choose 1 pc or a 2-piece pack (available on select sizes) so you can order exactly what your project requires without over-stocking raw material.

| Quantity per Pack | 1 pcs or 2 pcs (see variant options) |
| Application | Machining, engraving, fabrication, decorative hardware |
Start with your finished part dimensions and add material for any turning or facing operations — typically 1–2mm of stock allowance per side. For thickness, choose 5mm if your finished part is under 4mm thick, or 6mm if you need up to 5mm after facing. Use the variant selector above to pick your exact Thick × Diameter combination.
H62 brass has a tensile strength typically in the 330–420 MPa range, making it suitable for light-to-medium load applications such as spacers, bushings, and decorative hardware. It is not recommended for high-stress structural components where steel or bronze alloys would be more appropriate.
Brass does not rust (it contains no iron), but it can develop a natural patina (oxidation darkening) 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 machining. For marine or outdoor use, a protective coating is recommended.
Yes. H62 brass is well-suited to both soft soldering (with rosin-core or acid-core flux) and silver brazing. Ensure the surface is clean and free of oils before joining. Avoid overheating, as prolonged high heat can cause zinc volatilization (dezincification) in brass alloys.
Yes. H62 brass machines freely with standard HSS or carbide tooling. Use moderate speeds and feeds with a cutting fluid or light oil for best surface finish. The material produces short, manageable chips and is unlikely to work-harden during normal turning or milling operations.
The quantity option lets you choose how many discs you receive in a single order. The 2 pcs option is available on select sizes (currently 5mm × 10mm) and is useful when you need a spare blank or are making a matched pair of parts. All other sizes ship as 1 pc per order. Select your preferred quantity in the Amount variant above.
Discs are cut to nominal dimensions. Typical diameter tolerance is ±0.5mm and thickness tolerance is ±0.2mm for standard sizes. If your application requires tighter tolerances, plan to finish-machine the disc to your final dimension after receipt.
