When your project demands a flat, burr-free metal blank that fits exactly where you need it, undersized or poorly finished discs waste time and material. Makers, machinists, jewelers, and hardware enthusiasts who need reliable brass stock in a specific diameter and thickness will find these H62 brass round discs a dependable go-to for both prototyping and production runs.
Each disc is cut from H62 brass alloy sheet stock — a copper-zinc alloy known for its balance of machinability, corrosion resistance, and warm golden appearance. Diameters range from 10 mm (approx. 0.39 in) to 300 mm (approx. 11.81 in), with thickness options of 2 mm, 3 mm, 4 mm, 5 mm, and 6 mm (approx. 0.08 in – 0.24 in). Packing quantities vary by size to keep per-unit cost practical.
These solid brass discs are well-suited for custom gaskets and shims in plumbing or HVAC assemblies, decorative inlays and medallions in woodworking or furniture, electrical contact blanks and grounding pads in electronics fabrication, and turned or milled parts in hobby CNC and lathe projects requiring a non-ferrous round starting blank.

Select a diameter at least as large as the finished part you need — you can always machine or cut down, but you cannot add material. For thickness, choose the next size up from your minimum required thickness to allow for facing or surface finishing. Use the variant selector above to compare available diameter and thickness combinations.
H62 brass has a tensile strength of approximately 330–490 MPa depending on temper, which is adequate for light mechanical parts, shims, gaskets, and decorative hardware. It is not intended for heavy structural or high-impact load-bearing applications. For those, consider steel or bronze alternatives.
H62 brass performs well in air, fresh water, and mild environments. It is not suitable for exposure to strong acids, ammonia, or salt spray over extended periods without a protective coating. For marine or highly corrosive environments, consider applying a lacquer or sealant after finishing.
Yes. H62 brass solders and brazes readily using standard flux and silver solder or soft solder. Clean the surface with fine abrasive or flux before soldering to ensure a strong bond. Avoid overheating, as prolonged high heat can cause dezincification in some brass alloys.
Yes. H62 brass machines well with standard HSS (high-speed steel) or carbide tooling. Use moderate speeds and feeds, apply cutting fluid or lubricant for cleaner cuts, and avoid excessive tool pressure to prevent chatter on thinner discs. Standard twist drill bits work fine for drilling.
Smaller diameter discs (e.g., 10–20 mm) are available in 2 or 4-piece packs because projects often require multiples of small blanks. Larger diameters (e.g., 100 mm and above) are sold individually since each piece represents significantly more material. The variant selector shows the exact quantity included for each size combination.
Absolutely. H62 brass has a warm golden tone that polishes to a bright finish and accepts patination, engraving, and stamping well. Smaller diameters (10–50 mm) are popular for pendants, medallions, and decorative inlays. Sand or polish the mill surface before finishing for best results.
