When your project demands a clean, burr-free edge and a consistent alloy composition, sourcing the right brass flat stock can be a frustrating bottleneck. Whether you are a hobbyist machinist, a jewellery maker, or a professional fabricator, inconsistent thickness and ragged shear lines waste time and material. These guillotine-cut brass sheets are sized and sheared to order, giving makers and engineers a reliable starting point for every build.
Each piece is cut from C260 cartridge brass (70% copper / 30% zinc), delivering a warm golden finish and excellent machinability. Thickness options run from 0.5 mm (approximately 0.020 in) up to 6 mm (approximately 0.236 in), and sheet dimensions range from compact 50 × 50 mm (approx. 2 × 2 in) squares up to 300 × 300 mm (approx. 11.8 × 11.8 in) panels. All pieces are supplied flat and degreased, ready for immediate use.
Typical applications include custom shims and spacers for precision engineering, decorative inlay work and engraving blanks for craft projects, electrical contact strips and bus-bar prototyping, and structural gusset plates for scale-model or architectural model making. The wide thickness range makes these sheets equally suited to thin-gauge etching work and heavier structural fabrication tasks.

For decorative engraving, etching, or thin shims, 0.5–1 mm is typically sufficient. For structural brackets, gusset plates, or load-bearing components, 2–6 mm provides the rigidity needed. If you are unsure, a 1–1.5 mm sheet is a versatile starting point for most hobby and light engineering tasks.
C260 cartridge brass has a typical tensile strength of 300–400 MPa, making it suitable for light structural applications such as brackets, hinges, and spacers. For heavy-load or high-stress environments, thicker gauges (3–6 mm) are recommended. It is not intended as a structural steel replacement.
Brass forms a stable oxide layer that resists atmospheric corrosion well in dry and indoor environments. It outperforms mild steel significantly in humid conditions and is comparable to copper for general corrosion resistance. For marine or highly acidic environments, additional sealing or plating is advisable.
Yes. Brass is one of the most machinable metals. Thin sheets (0.5–1.5 mm) can be cut with tin snips, a jigsaw, or a CNC router. Thicker sheets (2–6 mm) are best cut with a bandsaw, angle grinder, or CNC mill. Standard HSS drill bits work well; use a cutting lubricant for cleaner holes and longer tool life.
Thin brass sheets (0.5–1 mm) can be marked with a fibre laser engraver. CO₂ lasers generally cannot cut or engrave bare brass without a coating (such as Cermark or black spray paint). For deep engraving or cutting, a fibre laser or CNC router is the recommended tool.
Select the smallest sheet size that accommodates your finished part dimensions, adding at least 5–10 mm on each side for clamping and cutting allowance. For example, a 40 × 40 mm shim is best cut from a 50 × 50 mm blank. This minimises waste while giving you enough material to work with safely.
Sheets are dispatched flat-packed and degreased. Thinner gauges (0.5–1 mm) may develop minor transit bow in larger sizes; if flatness is critical, place the sheet on a flat surface and apply gentle pressure, or pass it through a roller. Thicker sheets (2 mm and above) are inherently rigid and arrive flat.
