When your project demands a metal that combines workability with a warm, distinctive finish, finding a sheet cut to a consistent, burr-minimized edge can be a real challenge. Whether you are a hobbyist building decorative inlays, a maker fabricating custom brackets, or a small workshop producing shims and spacers, inconsistent cuts waste time and material. These natural brass sheet metal pieces are guillotine-cut for clean, straight edges that go straight to work.
Each piece is made from C260 cartridge brass (70% copper / 30% zinc), offering a balance of formability and structural integrity. Thickness options range from 0.5 mm (~0.020 in) up to 6 mm (~0.236 in), and sheet dimensions span from a compact 50 × 50 mm (~2 × 2 in) up to 300 × 300 mm (~11.8 × 11.8 in). Available in quantities of 1, 2, or 4 pieces per order to match your exact needs.
Typical applications include custom shim stock for machinery alignment, decorative metalwork and etching blanks, electrical contact strips and bus bar prototyping, and architectural accent panels for furniture and cabinetry. Long-tail use cases such as "thin brass sheet for laser engraving", "small brass plate for jewelry making", and "flat brass stock for CNC routing" are all well-served by this range.

For decorative inlays, etching, and shim stock, 0.5 mm–1 mm is typically sufficient. For structural brackets, spacers, and light load-bearing applications, 1.5 mm–3 mm offers a good balance of rigidity and workability. Thicknesses of 4 mm–6 mm are suited to heavier-duty parts where stiffness is critical. If you are unsure, start with a thinner gauge — brass is easy to stack or laminate if more thickness is needed.
C260 cartridge brass has a tensile strength of approximately 340–470 MPa depending on temper and thickness, making it suitable for light mechanical components such as spacers, shims, contact strips, and small brackets. It is not intended for high-stress structural applications where steel or thicker alloys would be more appropriate.
Brass naturally develops a patina over time when exposed to air and moisture. For indoor decorative use, this patina is often desirable. For applications requiring a bright finish, a clear lacquer or wax coating applied after purchase will slow tarnishing. Brass is not recommended for prolonged direct contact with salt water or harsh chemicals without a protective coating.
Yes. Thinner gauges (0.5 mm–1.5 mm) can be cut with aviation snips or a guillotine shear and bent by hand or with a sheet metal brake. Thicker gauges (2 mm–6 mm) are best cut with a band saw, jigsaw with a metal blade, or CNC router, and bent with a press brake or vise. Drilling is straightforward with standard HSS drill bits — use a slow speed and cutting fluid for cleaner holes.
Brass is an excellent material for CNC routing and mechanical engraving. For fiber laser engraving, brass works well with appropriate power settings. CO₂ lasers generally require a marking compound (such as Cermark) on bare brass to achieve visible marks. Always verify your machine's compatibility with non-ferrous metals before processing.
Order 1 piece for prototyping or one-off projects. Choose 2 pieces if you need a spare or are making a mirrored pair. Select 4 pieces for small production runs, classroom projects, or when you want to practice cuts and bends before committing to your final piece. Multi-piece orders offer a lower per-piece cost compared to single-piece orders of the same size.
Always select a sheet size larger than your finished part to allow for cutting margins and any clamping or fixturing allowance. For example, if your finished part is 80 × 80 mm, the 100 × 100 mm sheet gives you comfortable working room. If your part is close to a listed size, go one size up to avoid running short.
