When your project demands reliable electrical conductivity and dimensional accuracy, generic metal strips fall short. Makers, electronics hobbyists, and repair technicians working on grounding, shielding, heat-spreading, or decorative metalwork need a copper foil they can trust to spec. This 99.9% pure copper sheet roll delivers consistent thickness and width across every meter, so you can cut exactly what you need without waste or guesswork.
Each roll is made from 99.9% pure copper (Cu), available in thicknesses ranging from 0.01 mm to 1 mm (approximately 0.0004 in to 0.039 in) and widths from 10 mm to 400 mm (approximately 0.39 in to 15.75 in). Length options are 300 mm or 1 meter per piece. The surface is smooth-rolled with a natural copper finish, offering excellent solderability and low contact resistance.
Typical use cases include EMI/RFI shielding tape for electronics enclosures, copper bus bar fabrication for DIY battery packs and solar installations, heat-spreader shims for CPU or LED thermal management, and decorative inlay work in woodworking or jewelry making. The flexible, rollable format makes it easy to store and cut to custom lengths on the bench.

For EMI/RFI shielding tape and flexible wrapping, 0.05–0.1 mm is typically sufficient. For heat-spreader shims and thermal pads, 0.2–0.5 mm provides better thermal mass. For bus bars, grounding straps, or structural applications, 0.5–1 mm offers the rigidity and current-carrying capacity needed. If you are unsure, select the variant options above to compare dimensions, or contact us to confirm suitability.
Width should match your application footprint. Narrow strips (10–25 mm) suit PCB grounding traces, battery tab connections, and jewelry inlay. Medium widths (30–100 mm) work well for heat spreaders and shielding panels. Wide strips (100–400 mm) are suited for large-format shielding, bus bar fabrication, and sheet-metal craft work. Select your width from the variant options above.
Thinner gauges (0.01–0.1 mm) are intended for electrical, thermal, and decorative applications — not structural load-bearing. Thicker stock (0.5–1 mm) has meaningful rigidity and can be used for light mechanical brackets or bus bars, but is not rated for heavy structural loads. For mechanical strength requirements, please contact us to confirm the appropriate gauge.
Pure copper naturally oxidizes to form a stable copper oxide layer (darkening or patina) when exposed to air and moisture. This patina is protective and does not significantly degrade electrical conductivity in most applications. For environments with high humidity, salt air, or chemical exposure, consider applying a clear lacquer or conformal coating after installation to slow further oxidation.
Yes. The smooth-rolled surface accepts standard rosin-core and water-soluble flux solders without special preparation. For best results, lightly abrade the surface with fine sandpaper or a fiberglass pen to remove any surface oxide before soldering, then apply flux and solder normally. This strip is compatible with standard electronics and plumbing soldering temperatures.
This strip is 99.9% pure copper, which is functionally equivalent to C11000 ETP copper in terms of conductivity and workability. It is suitable for the same electrical, thermal, and general fabrication applications. If your project requires a specific ASTM or EN certification, please contact us before ordering to confirm compliance.
Yes. The strips are supplied in 300 mm or 1 meter lengths, and you can easily cut them to any shorter dimension using scissors (for thin gauges ≤0.2 mm), tin snips, or a utility knife with a metal straightedge. Thicker gauges (0.5–1 mm) may require tin snips or a metal shear for a clean cut.
