Copper Sheet Roll Metal Foil Plate 0.05-1mm Thick 15-90mm Width, Various lengths

For EMI and RF shielding, 0.05 mm to 0.1 mm is typically sufficient — the skin depth of copper at most RF frequencies is well under 0.05 mm. For heat-spreading or grounding straps where mechanical rigidity matters, 0.3 mm to 0.5 mm offers a good balance of flexibility and stiffness. For structural shims or decorative inlays that need to hold shape, 0.6 mm to 1 mm is recommended. If you are unsure, select the variant options above or contact us to confirm.

Common PCB ground straps run 10 mm to 25 mm wide. For shielding enclosure seams, 15 mm to 30 mm covers most standard chassis gaps. Wider strips (50 mm and above) are better suited for large flat panels, heat spreaders, or decorative applications where coverage area matters more than flexibility.

Thin gauges (0.05 mm – 0.2 mm) are foil-grade and are not intended for structural load-bearing. They are designed for electrical, thermal, and decorative applications. Thicker gauges (0.5 mm – 1 mm) have meaningful tensile strength and can serve as shims, spacers, or light structural elements, but should not be used as primary load-bearing components in safety-critical assemblies.

Bare copper will oxidise and develop a patina when exposed to air and moisture. This surface oxide layer is non-conductive, so for electrical contact applications you should tin the surface with solder, apply a conductive coating, or keep the copper sealed. For decorative applications, a clear lacquer spray will preserve the bright copper appearance. In dry indoor environments, tarnishing is slow and largely cosmetic.

Yes. Bare copper solders readily with standard rosin-core or water-soluble flux and 60/40 or lead-free solder. For best results, lightly abrade the surface with fine sandpaper or a fibreglass pen to remove any surface oxide before soldering, then apply flux immediately before tinning. Thinner gauges (under 0.1 mm) heat up very quickly, so use a low-wattage iron and work fast to avoid warping.

No. This product is bare copper flat stock with no adhesive backing. It is a raw metal strip intended for soldering, mechanical fastening, or press-fit applications. If you need self-adhesive copper tape for stained glass or surface mounting, that is a different product category. The advantage of bare copper is that the full surface is solderable and there is no adhesive residue to interfere with electrical contact.

For gauges up to 0.3 mm, sharp scissors or a craft knife and steel ruler work well. For 0.4 mm to 0.6 mm, aviation tin snips give a clean straight cut. For 0.8 mm to 1 mm, a rotary tool with a thin cutting disc or a bench shear produces the cleanest edge. Score-and-snap is not recommended for copper as it tends to deform rather than fracture cleanly.
