When your project demands a conductive, corrosion-resistant metal that can be cut, shaped, and soldered with ease, finding the right copper foil in the exact thickness and width is rarely straightforward. Whether you are a maker building EMI shielding enclosures, an electronics hobbyist laying ground planes, or a craftsperson working with stained glass or decorative inlays, this copper sheet roll gives you the dimensional precision you need without ordering custom stock.
Each roll is pure copper flat stock, available in thicknesses from 0.05 mm to 1 mm (approximately 0.002 in to 0.039 in) and widths from 10 mm to 120 mm (approximately 0.39 in to 4.72 in). Length options of 1 m, 2 m, 5 m, 10 m, and 20 m let you order exactly what the job requires. The foil ships in a continuous roll, free of joints or splices within the selected length.
Typical use cases include RF and EMI shielding tape for electronics enclosures, copper inlay work in woodworking and resin casting, heat-spreading strips in DIY thermal management builds, grounding straps for audio equipment, and decorative metalwork in jewellery and stained-glass projects. Long-tail search terms that describe this product: thin copper strip roll, copper foil tape without adhesive, copper flat bar strip, copper shim stock roll, pure copper sheet by the meter.

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.
