When your project demands a material that holds tight tolerances, resists corrosion, and machines cleanly, finding the right brass sheet in the exact thickness you need can be a real challenge. Whether you are a hobbyist building custom enclosures, a maker crafting decorative inlays, or a small workshop producing shims and gaskets, these H62 brass guillotine offcuts give you a reliable, ready-to-use starting point without ordering full commercial sheets.
Each piece is cut from H62 grade brass alloy — a copper-zinc composition (approximately 62% copper) known for its balance of strength, machinability, and corrosion resistance. Available in thicknesses ranging from 0.5 mm (0.020 in) to 6 mm (0.236 in), with flat dimensions spanning from 50×50 mm (approx. 2×2 in) up to 300×300 mm (approx. 11.8×11.8 in). Surfaces are mill-finished with a characteristic golden-yellow tone.
Typical applications include custom shim stock and precision spacers for mechanical assemblies, decorative brass inlay panels for woodworking and furniture making, electrical contact strips and grounding tabs for DIY electronics projects, and thin gasket blanks for fluid or pneumatic fittings in small-scale fabrication.

For shims, gaskets, and thin decorative inlays, 0.5–1 mm is typically sufficient. For structural brackets, spacers, or parts that will be drilled and tapped, 2–4 mm provides better thread engagement and rigidity. For heavy-duty load-bearing plates or thick decorative panels, 5–6 mm is recommended. When in doubt, select one step thicker than your minimum requirement to allow for surface finishing.
H62 brass has a tensile strength of approximately 330–420 MPa, which is adequate for light-to-medium mechanical applications such as spacers, bushings, contact strips, and decorative hardware. It is not intended for high-stress structural applications where steel or aluminium alloy would be more appropriate. For prototyping and workshop fabrication, H62 performs reliably.
H62 brass does not rust (it contains no iron), but it will develop a natural patina — a darker golden-brown or greenish tint — when exposed to moisture, humidity, or atmospheric pollutants over time. For indoor applications this is generally not an issue. For outdoor or marine environments, applying a clear lacquer or wax coating will significantly extend the bright finish. Brass is inherently more corrosion-resistant than mild steel in most conditions.
Yes. H62 brass is well-suited to both soft soldering (using standard electronics or plumbing solder with appropriate flux) and silver brazing. Ensure the surface is clean and free of oils or oxidation before joining. Avoid overheating thin sheets (0.5–1 mm) as they can warp; use a heat sink or clamp to manage thermal spread.
Thin sheets (0.5–1.5 mm) can be cut with aviation tin snips, a bench shear, or a jigsaw fitted with a fine-tooth metal blade. Thicker sheets (2–6 mm) are best handled with a band saw, cold saw, or angle grinder with a metal cutting disc. For precise shapes, a CNC router or waterjet cutter works well. Always deburr edges after cutting using a file or deburring tool.
Guillotine-sheared offcuts are cut straight and are generally flat within standard sheet-metal tolerances. Thinner gauges (0.5–1 mm) may exhibit minor bow or curl from the coil, which can be flattened by hand or with a rubber mallet on a flat surface. Dimensional tolerance is typically ±0.1–0.3 mm depending on thickness. If your application requires tighter flatness, light surface grinding or lapping may be needed.
Select the smallest variant whose flat dimensions are equal to or larger than your finished part. For example, if your part is 85×85 mm, order the 100×100 mm size to allow for layout lines and cutting margin. This minimises material waste while ensuring you have enough stock to work with. For rectangular parts, choose a variant where both width and length dimensions exceed your part dimensions.
