When your project demands a flat, dimensionally accurate metal blank and you can't afford warped edges or rough cuts, sourcing the right brass sheet becomes a real challenge. Whether you're a hobbyist machinist, a small-shop fabricator, or a maker building custom enclosures, you need stock that arrives ready to work — not stock that needs hours of cleanup. These brass sheet metal plates are guillotine-cut to your chosen dimensions so you can go straight from unboxing to layout.
Each plate is cut from C26000 cartridge brass (70% copper, 30% zinc), delivering a warm golden finish with good machinability and moderate corrosion resistance. Thickness options span 1.2 mm to 10 mm (~0.047" to ~0.394"), and width/length combinations range from 10 mm × 10 mm up to 400 mm × 400 mm (~0.39" × 0.39" to ~15.75" × 15.75"), with select rectangular cuts available up to 200 mm × 600 mm (~7.87" × 23.62").
Typical applications include RF/EMI shielding panels for electronics enclosures, decorative inlay and engraving blanks for woodworking and jewelry, bearing spacers and shim stock for mechanical assemblies, and custom bracket or gusset blanks for light structural fabrication. The guillotine shear produces a clean, square edge that is ready for drilling, milling, bending, or soldering without secondary deburring on most thicknesses.

For shielding panels, decorative inlays, and thin shims, thicknesses of 1.2 mm – 2 mm are typically sufficient. For structural brackets, bearing spacers, or parts that will be tapped for threads, 3 mm – 6 mm provides more material for thread engagement and rigidity. Thicknesses of 8 mm – 10 mm are suited to heavy-duty blanks where significant machining stock is needed.
C26000 brass has a typical tensile strength of around 330 MPa, which is lower than mild steel (~400 MPa) but higher than common 6061 aluminum (~310 MPa). Brass is not intended for high-load structural applications but performs well in brackets, spacers, decorative hardware, and electrical components where moderate strength and good machinability are priorities.
Brass offers moderate corrosion resistance and performs well in dry indoor environments and lightly exposed outdoor settings. In humid, marine, or chemically aggressive environments, brass can develop a patina (verdigris) over time. For long-term outdoor exposure, consider applying a clear lacquer or wax coating to the surface after fabrication.
Yes. C26000 cartridge brass is one of the most solderable copper alloys. It accepts soft solder (tin-lead or lead-free) readily with standard flux, and can also be silver-brazed for higher-strength joints. Clean the surface with fine abrasive or flux before soldering to ensure good adhesion.
For thinner plates (1.2 mm – 2 mm), a bench shear, aviation snips, or a jigsaw with a metal-cutting blade works well. For thicker plates (3 mm and above), a band saw, milling machine, or CNC router with non-ferrous tooling is recommended. Drilling requires standard HSS or cobalt drill bits at moderate speed with cutting fluid to prevent work-hardening and extend bit life.
Measure your finished part dimensions and add at least 2–5 mm on each edge for layout lines and any cleanup cuts. Choose the next available size up from your finished dimensions. For rectangular parts, check whether a rectangular variant (e.g., 50 mm × 100 mm or 100 mm × 200 mm) is available to reduce offcuts compared to ordering a square plate and cutting it down.
Yes. The mill-finish surface of these plates is well-suited for rotary engraving, laser engraving (CO2 or fiber laser with appropriate settings), and chemical etching. For laser engraving, a fiber laser produces the sharpest results on bare brass. Applying a marking spray before CO2 laser engraving can also produce good contrast.
