When your project demands a flat, true-round metal blank that holds detail and machines cleanly, finding the right starting stock can be frustrating. Hobbyists, jewelers, engravers, and small-shop machinists all share the same need: a solid brass disc that arrives flat, burr-free, and ready to work. These solid brass disc blanks are stocked in a wide matrix of thicknesses and diameters so you can match the exact spec your project calls for without over-buying sheet stock and cutting it yourself.
Each disc is cut from solid brass (CuZn alloy, commonly C260 / cartridge brass composition), delivering the warm golden tone and excellent workability brass is known for. Thickness options run from 0.5 mm (~0.020 in) up to 3 mm (~0.118 in), and diameters span 20 mm (~0.79 in) to 200 mm (~7.87 in). The smooth, flat faces are suitable for stamping, engraving, etching, and light turning without additional surface prep.
Typical use cases include hand-stamped jewelry tags and pendants, clock-face and dial blanks for watchmaking or instrument restoration, custom name-plate and trophy inserts, gasket prototypes and shim stock for mechanical assemblies, and decorative inlay rounds for woodworking and leathercraft. Whether you need a single piece to test a design or a set of three for a production run, the quantity options let you order exactly what you need.

Thinner discs (0.5 mm–1 mm) are ideal for jewelry tags, pendants, and engraving blanks where flexibility and low weight matter. Mid-range thicknesses (1.5 mm–2 mm) suit name plates, dial faces, and decorative inlays that need to hold their shape under light pressure. The thickest option (3 mm) is best for structural shims, gasket prototypes, or turned parts that require rigidity and material to remove during machining.
For standard pendant blanks, 20 mm–30 mm discs are the most popular choice — they fit comfortably as a coin-sized charm. Larger diameters (50 mm–80 mm) work well for statement pieces, brooch bases, or small decorative plates. If you are unsure, ordering a 1-piece quantity in your target size lets you test the fit before committing to more.
Brass offers moderate tensile strength (typically 300–500 MPa depending on temper) and is well-suited for light mechanical applications such as shims, spacers, and gasket prototypes. It is not recommended for high-load structural applications where steel or aluminum alloys would be more appropriate. For decorative, engraving, and light-duty mechanical uses, brass performs reliably.
Brass has good natural corrosion resistance in dry indoor environments. Over time, exposure to air and moisture causes the surface to develop a patina (darkening or greening). This can be slowed by applying a clear lacquer or wax coating after finishing. If a bright, lasting finish is required, consider having the disc plated or sealed after your work is complete.
Yes. Brass responds well to fiber laser and MOPA laser marking, producing dark, high-contrast marks on the natural surface. CO₂ lasers alone are generally not effective on bare brass without a marking compound. For rotary or CNC engraving, brass is one of the easiest metals to engrave cleanly due to its machinability.
The Amount option lets you select how many identical discs (same thickness and diameter) you receive in a single order. Ordering 2 or 3 pieces at once typically offers a lower per-piece cost compared to placing separate single-piece orders. This is useful when you need duplicates for a matched set, want a spare in case of a mistake during fabrication, or are running a small production batch.
Yes. Brass solders and brazes readily using standard silver solder, soft solder (tin-lead or lead-free), or brass brazing rod with appropriate flux. Clean the surface with fine abrasive or flux before joining to ensure a strong bond. Brass is a common choice in jewelry making and plumbing precisely because of its excellent solderability.
