When your project demands exact thickness tolerances and reliable conductivity, standard hardware store sheet metal simply won't cut it. Makers, electronics hobbyists, jewelers, and small-workshop fabricators who need ultra-thin copper sheet strip in controlled gauges — from a hair-fine 0.01mm all the way up to a structural 1mm — will find this listing covers the full spectrum in one place.
Each strip is cut from C101 (99.9%+ purity) electrolytic tough-pitch copper, delivering excellent electrical and thermal conductivity alongside a naturally soft, workable temper. Strips are available in widths of 100mm (~3.94 in), 150mm (~5.91 in), 200mm (~7.87 in), and 300mm (~11.81 in), with a standard length of 1 meter (~39.37 in) per piece. Thickness ranges from 0.01mm (0.0004 in) to 1mm (0.039 in) depending on the variant selected.
Typical use cases include EMI/RFI shielding gaskets and enclosure liners, battery tab and busbar fabrication for DIY power packs, decorative inlay work and metalsmithing, heat-spreader shims in electronics repair, and precision feeler-gauge shimming in mechanical assemblies. Long-tail searches this product satisfies: thin copper foil strip roll for shielding, pure copper sheet metal for jewelry making, flexible copper strip for battery tabs, C101 copper shim stock.

For EMI/RFI shielding gaskets, 0.05mm–0.1mm is typically sufficient. For battery tabs and busbars carrying moderate current, 0.2mm–0.5mm is common. For structural shims or heat spreaders, 0.5mm–1mm provides rigidity. If you are unsure, start with a mid-range thickness (0.1mm–0.2mm) and test fit before committing to a larger quantity.
These strips are C101 electrolytic tough-pitch copper, which is 99.9%+ pure copper. It is not brass, bronze, or a copper-clad material. This makes it suitable for applications requiring high conductivity and easy soldering.
Copper naturally oxidizes when exposed to air and moisture, forming a brownish or greenish patina over time. This patina is stable and does not compromise structural integrity. For applications where a bright finish is required, apply a thin clear lacquer or store strips in a sealed bag with a desiccant until use.
Yes. C101 copper solders readily with standard rosin-core or water-soluble flux and common tin-lead or lead-free solder alloys. Lightly abrade the surface with fine-grit sandpaper or a fiberglass pen before soldering to remove any surface oxide for best adhesion.
Strips up to approximately 0.1mm thick can be cut cleanly with sharp metal-cutting scissors or a craft knife and steel ruler. Thicker gauges (0.2mm and above) are better cut with tin snips, a guillotine shear, or a rotary cutter designed for non-ferrous sheet. Always deburr cut edges with a fine file or sandpaper.
Very thin gauges (typically 0.01mm–0.1mm) may arrive lightly coiled due to their flexibility. Thicker gauges (0.2mm and above) are generally flat. If you need a perfectly flat piece, place the strip on a flat surface and apply gentle, even pressure, or run it through a hand roller to remove any curl.
For standard 18650 or 21700 cell packs, a 100mm wide strip is commonly cut down to 8mm–20mm tab widths, making it very economical. For larger prismatic cells or busbar work, the 200mm or 300mm width reduces the number of cuts needed and minimizes waste.
