When your project demands a metal flat bar that holds tight tolerances without the hassle of cutting raw stock yourself, finding the right size in the right alloy can eat up hours. Makers, hobbyists, machinists, and small-shop fabricators who need ready-to-use brass or copper strip stock will find this listing covers the widest range of cross-sections in one place.
Each piece is a solid rectangular flat bar available in thickness from 2 mm to 9 mm (~0.08 in to 0.35 in) and width from 8 mm to 60 mm (~0.31 in to 2.36 in), with lengths of 200 mm (~7.87 in) or 500 mm (~19.69 in). The material is brass (a copper-zinc alloy) with a smooth mill finish, offering good machinability, moderate strength, and inherent corrosion resistance.
Typical applications include electrical bus bars and grounding straps, decorative inlay and trim work for woodworking projects, custom bracket and spacer fabrication for mechanical assemblies, and RF shielding or heat-sink tabs in electronics enclosures — all scenarios where a brass flat bar or copper plate strip delivers reliable performance.

Start with the load or clearance requirement of your application. For decorative inlay or trim, thinner stock (2–3 mm) is easier to bend and cut. For structural brackets or bus bars carrying current, thicker stock (5–9 mm) provides more rigidity and cross-sectional area. Select the width to match your slot, channel, or contact pad dimension. Use the Size (Thick × Width × Length) variant selector above to find your exact cross-section.
Brass is a copper-zinc alloy. It is harder and more machinable than pure copper, with a golden-yellow color. Pure copper is softer, has higher electrical and thermal conductivity, and has a reddish tone. This listing covers brass flat bar stock. If your application requires maximum conductivity (e.g., heavy electrical bus work), pure copper may be preferable; for general fabrication, machining, and decorative use, brass is an excellent choice.
Yes. Brass solders readily with standard rosin-core or acid-core solder and appropriate flux. For higher-strength joints, silver brazing with a torch is also effective. Clean the surface with fine abrasive or flux before soldering to ensure a good bond. Avoid overheating, which can cause zinc fuming in brass — work in a ventilated area.
For cutting, a hacksaw, band saw, or angle grinder with a metal-cutting disc works well. For drilling, standard HSS twist drill bits are sufficient for most thicknesses; use cutting fluid to extend bit life and improve hole quality. Brass machines cleanly and does not work-harden significantly, so standard woodworking drill press speeds (with appropriate bits) can be used for thinner stock.
Brass does not rust (rust is specific to iron-based metals). It can develop a natural patina (darkening or greenish tarnish) over time when exposed to moisture and air. For indoor applications this is typically slow and cosmetic only. To maintain a bright finish, apply a clear lacquer or metal polish. For outdoor or high-humidity environments, periodic cleaning and sealing is recommended.
Yes, brass flat bar can be bent at moderate radii without cracking, especially in the annealed or half-hard condition. As a general guideline, keep the inside bend radius at least equal to the material thickness to avoid cracking. For tighter bends, anneal the piece by heating to dull red and quenching in water before bending. Thicker stock (6 mm and above) may require a press brake or bending jig for consistent results.
If you need a single piece to prototype or complete a one-off repair, select 1 Pc. If you are stocking your workshop or completing a project that requires multiple identical pieces, a multi-pack reduces per-unit cost and ensures you have spares. Check the Pack quantity(Pcs) variant option to see available quantities for your chosen size.
