When your project demands a flat, dimensionally accurate metal blank that machines cleanly and resists corrosion without special coatings, finding the right disc in the right size can be frustrating. Hobbyists, machinists, and small-workshop fabricators who need a reliable starting stock for gaskets, spacers, decorative inlays, or custom parts will find these H62 brass round discs a dependable choice.
Each disc is cut from H62 brass alloy sheet — a copper-zinc alloy known for its balance of workability and moderate strength. Available in three thicknesses (0.3 mm / ~0.012 in, 0.5 mm / ~0.020 in, and 0.8 mm / ~0.031 in) and diameters ranging from 10 mm (~0.39 in) to 300 mm (~11.81 in), the discs ship as flat, solid plates with no center hole.
Typical applications include DIY gasket blanking for plumbing and pneumatic fittings, decorative inlay work in woodworking and jewelry making, shim stock and spacer fabrication for mechanical assemblies, and prototype flat-part machining where a pre-cut brass disc saves setup time over raw sheet stock.

For thin gaskets, shims, or decorative inlays where flexibility matters, the 0.3 mm disc is a good starting point. The 0.5 mm option balances rigidity and workability for general-purpose spacers and craft blanks. Choose 0.8 mm when you need a stiffer plate that can withstand moderate mechanical load without deforming during machining or assembly.
Measure the outer dimension of the area you need to cover or fit, then select the next size up to allow for trimming. For example, if your bore is 48 mm, a 50 mm disc gives you a small margin to machine or file to final size. For decorative inlays, match the diameter to your recess as closely as possible.
H62 brass has a typical tensile strength of approximately 330–420 MPa and is well-suited for light-to-moderate mechanical applications such as spacers, washers, and non-structural brackets. It is not recommended for high-stress structural components or applications subject to heavy impact loads.
H62 brass naturally develops a thin oxide layer that slows further corrosion in typical indoor environments. In humid or mildly corrosive conditions, the surface may tarnish to a darker golden-brown tone over time. Applying a clear lacquer or wax coating after machining can preserve the original finish if appearance is important for your application.
Yes. H62 brass solders well with standard soft solders and brass-compatible flux. It can also be brazed using silver-based brazing alloys. Clean the surface with a mild abrasive or flux before soldering to remove any oxide layer and ensure a strong joint.
Yes. H62 brass machines cleanly on CNC mills and lathes with standard brass-grade tooling and cutting fluid. Thinner discs (0.3 mm and 0.5 mm) can also be cut with a fiber laser cutter. For waterjet cutting, all three thicknesses are suitable. Always secure thin discs firmly to prevent vibration during machining.
If you are prototyping or need a single part, the 1-piece option avoids unnecessary stock. The 4-piece pack is practical when you expect to make a few test cuts before finalizing your design. The 10-piece pack offers the best per-unit value for production runs or when you need spares on hand for ongoing maintenance tasks.
