Finding a flat, consistently dimensioned metal blank that machines cleanly and holds its shape through cutting, drilling, and finishing is a recurring challenge for makers, electronics builders, and repair technicians. This H62 brass sheet plate in a 300 × 300 mm square format is stocked to eliminate that friction — one size, multiple thicknesses, ready to cut to your exact requirement.
Each panel is produced from H62-grade brass alloy, a copper-zinc composition with approximately 62% copper content, valued for its machinability, moderate tensile strength, and warm golden surface. The square footprint measures 300 × 300 mm (approx. 11.81 × 11.81 in), with thickness options ranging from 0.5 mm to 6 mm (approx. 0.020 in to 0.236 in). The mill-finished surface is smooth and uncoated, providing a consistent base for further processing.
Typical applications include RF and EMI shielding panels for electronics enclosures, engraving and etching blanks for signage and identification plates, shim stock and gasket material for mechanical assemblies, and decorative inlay panels for woodworking and jewelry fabrication. The larger 300 × 300 mm footprint is particularly useful when cutting multiple smaller pieces from a single blank or when a part layout requires more surface area than a narrower sheet provides.

For flexible shim stock, gaskets, or thin decorative inlay, 0.5–0.8 mm is typically sufficient. For structural brackets, RF shielding panels, or parts that will be drilled and tapped, 1.5–3 mm provides better rigidity. Thicknesses of 4–6 mm are suited to heavy-duty blanks, engraving plates, or applications requiring significant material removal during machining.
The 300 × 300 mm square format gives you more usable surface area per panel. This is particularly useful when you need to cut multiple smaller pieces from a single blank, when your part layout is wider than a 200 mm panel allows, or when you want to minimize the number of separate pieces you need to order for a project.
H62 brass has a typical tensile strength of approximately 330–420 MPa, which is adequate for light-to-moderate mechanical applications such as brackets, spacers, and bushings. It is not recommended for high-stress structural components where steel or bronze alloys would be more appropriate. For decorative, shielding, and precision-fit applications it performs reliably.
H62 brass naturally develops a thin oxide layer that slows further surface degradation. In dry indoor environments, visible tarnishing is gradual. In humid or outdoor conditions, the surface will develop a darker patina over time. Applying a clear lacquer or wax coating after fabrication will preserve the original warm-gold appearance if that is important for your application.
Yes. H62 brass has excellent solderability. Standard flux-core electrical solder, silver solder, and brazing rods all bond well to the surface. Clean the area with isopropyl alcohol or fine abrasive before soldering to remove any surface oxidation and ensure a strong joint.
H62 brass can be marked with fiber laser engravers and CO₂ lasers equipped with a metal-marking spray (such as Cermark). Fiber lasers at appropriate power settings will engrave directly into the surface. The smooth mill finish provides a consistent base for clean, high-contrast engraving results.
Thinner variants (0.5–1 mm) can be cut with aviation snips or heavy-duty scissors. Thicknesses from 1.2 mm upward are best handled with a jigsaw fitted with a metal-cutting blade, a hacksaw, or a CNC router. Drilling is straightforward with standard HSS drill bits; use cutting fluid to extend bit life and achieve cleaner holes.
