When a project demands a brass strip that resists deflection under load but still cuts and bends without specialist tooling, 0.5mm is the gauge that delivers. Mechanical engineers shimming bearing housings, electronics fabricators forming leaf-spring contacts, and woodworkers cutting structural inlay banding all reach for a 0.5mm brass sheet roll when thinner foils lack the backbone the job requires.
This brass sheet roll is 0.5mm thick and supplied in 1000mm (39.4 in) lengths. Width options run from 5mm (0.20 in) to 400mm (15.75 in) across 22 variants, letting you select the exact coverage your application needs. The alloy is a standard copper-zinc brass composition with a mill-finish golden surface, offering a reliable combination of ductility, moderate tensile strength, and good solderability.
Typical applications include precision shim stock for machine tool and bearing adjustments, leaf-spring contact strips in low-current electrical assemblies, decorative banding and inlay work in furniture and cabinetry, and thin structural facing panels in scale model engineering. The 0.5mm gauge is also a practical choice for EMI shielding gaskets and grounding straps where mechanical durability matters alongside conductivity.

The 0.5mm strip is 25% thicker than 0.4mm and 67% thicker than 0.3mm, which produces a meaningful increase in stiffness. Choose 0.5mm when the strip needs to resist deflection under light mechanical load — for example, as a leaf-spring contact, a structural inlay, or a shim that must not compress under clamping force. Choose 0.3mm or 0.4mm when flexibility and tight-radius forming are the priority.
Select a width that matches or slightly exceeds the widest dimension of your target area. For shims and spacers, choose the narrowest width that fully covers the joint. For shielding panels or decorative banding, measure the opening and pick the next width up. All variants share the same 0.5mm thickness and 1000mm length — only the width changes between options.
Yes, though the added thickness compared to thinner foils means heavy-duty tin snips or a dedicated metal shear will give cleaner results than scissors. For long, straight cuts on wider strips, a guillotine-style metal shear or CNC router is recommended. Score-and-snap is not advised — shear in a single pass for the cleanest edge and to avoid work-hardening along the cut line.
Yes — 0.5mm brass is a common gauge for light-duty leaf springs and electrical contact strips in low-current applications. It provides enough spring-back after bending to function as a contact element, while remaining workable with hand tools. For high-cycle fatigue applications or elevated temperatures, consult a materials engineer to confirm suitability.
Brass develops a natural patina in humid or outdoor environments. For indoor applications — electronics, furniture inlays, model making — the surface remains stable for years without treatment. To preserve the bright golden finish, apply a thin coat of clear lacquer or metal wax after cleaning. For outdoor or marine use, a protective coating is recommended.
Yes. Brass solders readily with standard rosin-core or acid-core solder and an appropriate flux. For brazing, use a brass-compatible brazing rod and ensure the surface is clean and oxide-free. The 0.5mm gauge handles torch heat well compared to thinner foils, but avoid dwelling in one spot to prevent localised warping.
At 0.5mm, brass offers a practical balance of stiffness, workability, and corrosion resistance. Copper at the same gauge is softer and more conductive but more expensive and prone to surface oxidation. Stainless steel is harder and more corrosion-resistant but significantly more difficult to cut, bend, and solder. Brass is the most versatile option for most DIY, craft, and light engineering applications at this gauge.
