When your project demands a flat, true-running metal blank that machines cleanly and holds tight tolerances, generic sheet offcuts fall short. Whether you are a hobbyist turning custom gaskets on a lathe, a maker engraving decorative medallions, or a small workshop fabricating shims and spacers, these H62 brass disc blanks give you a ready-to-use circular starting point — no band-saw time, no wasted material.
Each disc is cut from H62 brass alloy (approximately 62% copper, 38% zinc), delivering a balance of machinability, corrosion resistance, and warm golden appearance. Diameters range from 50 mm (≈ 2.0 in) to 200 mm (≈ 7.9 in); thickness options span 0.8 mm (≈ 0.031 in) to 3 mm (≈ 0.118 in). Packs are sized to match typical project quantities — from single large-diameter sheets to multi-piece sets for smaller diameters.
Typical use cases include: CNC-turned brass shim discs for mechanical assemblies, hand-engraved brass medallions and name tags for awards and signage, and custom gasket blanks for plumbing or pneumatic fittings where a soft, machinable metal is required.
Approximately 62% copper content delivers excellent machinability, a clean chip break on the lathe, and a naturally corrosion-resistant surface — no coating required for most indoor applications.
Diameters from 50 mm to 200 mm paired with thickness options from 0.8 mm to 3 mm give you the flexibility to match your exact project spec without secondary cutting operations.
Smaller 50 mm discs are available in packs of up to 10 sheets; larger 200 mm discs ship as single sheets — so you pay for what you actually need rather than oversized bulk lots.
Pre-cut to a round profile, these blanks eliminate the time and waste of cutting circles from rectangular sheet stock, letting you go straight to finishing operations.
H62 brass forms a stable oxide layer that resists moisture and mild chemical exposure, making these discs suitable for decorative hardware, marine-adjacent accessories, and outdoor signage blanks.
Used by machinists for shims and spacers, by jewellers and engravers for medallion blanks, and by plumbers and engineers for custom gasket stock — one product, many applications.

Start with your finished part dimensions and add machining allowance — typically 1–2 mm on the diameter and 0.2–0.5 mm on the thickness. For shims and gaskets, match the thickness to your required gap. For decorative medallions, the 50 mm and 100 mm diameters in 1–2 mm thickness are the most popular starting points.
H62 brass has a tensile strength of approximately 330–440 MPa and a Brinell hardness of around 80–100 HB, making it suitable for light-to-medium load shims, spacers, and bearing thrust washers. It is not recommended for high-impact or heavy structural applications where steel or bronze would be more appropriate.
H62 brass naturally develops a patina over time when exposed to moisture and air. For outdoor or marine-adjacent use, a clear lacquer or wax coating will preserve the bright finish. The alloy itself resists rust and mild chemical exposure well, making it suitable for decorative hardware and signage in sheltered outdoor environments.
Yes. H62 brass is one of the most machinable copper alloys. It cuts cleanly with standard HSS or carbide tooling at typical brass cutting speeds (surface speed approximately 60–120 m/min for HSS). Minimal cutting fluid is required; a light oil or brass-rated coolant is sufficient for most operations.
Brass gaskets are commonly used in low-to-medium pressure plumbing and pneumatic applications. The 0.8 mm and 1 mm thickness options are well suited for face-seal gaskets. Always verify the pressure rating and chemical compatibility with your specific fluid or gas before use in critical systems.
Pack quantities are matched to disc diameter to keep order weights practical. Smaller 50 mm discs are available in packs of 2, 3, 5, or 10 sheets; 100 mm discs come in packs of 1 or 2; 150 mm and 200 mm discs are sold as single sheets. Select your preferred pack size using the "Pack of" option above.
H62 brass solders and brazes readily using standard silver solder or brass brazing rod with appropriate flux. Fusion welding is possible but requires care to manage zinc fuming — TIG welding with proper ventilation is the preferred method. Soft soldering with rosin-core solder works well for electrical or light decorative joints.
