When your project demands reliable electrical conductivity and consistent thickness, standard hardware-store metal simply won't cut it. Whether you're a maker building custom PCB shielding, a hobbyist crafting decorative metalwork, or a small workshop fabricating gaskets and heat spreaders, sourcing the right copper stock in the exact dimensions you need is a constant challenge. These 99.9% pure copper sheet foil strips are stocked in a wide range of thicknesses and widths so you can order precisely what your build requires — no waste, no guesswork.
Each strip is rolled from 99.9% pure copper (C11000 / ETP grade), delivering excellent electrical and thermal conductivity. Thickness options range from 0.01 mm to 1 mm (approximately 0.0004 in to 0.039 in), and widths span 10 mm to 300 mm (approximately 0.39 in to 11.81 in). Standard length is 1 meter (approx. 39.4 in), with select combinations also available in 300 mm and 500 mm cut lengths. The surface is smooth-rolled with a bright copper finish.
Typical use cases include EMI/RF shielding tape for electronics enclosures, conductive foil for battery tab connections and grounding straps, thin shim stock for precision mechanical clearance adjustment, decorative inlay and craft metalwork, and heat-spreader foil in DIY thermal management applications.

For EMI/RF shielding and battery tab connections, 0.05 mm – 0.1 mm foil is typically sufficient. For conductive gaskets and flexible bus bars, 0.2 mm – 0.5 mm offers a good balance of flexibility and current capacity. For rigid shims, heat spreaders, or structural applications, 0.8 mm – 1 mm strip is recommended. If you're unsure, start with 0.1 mm for general-purpose foil work.
Yes. C11000 ETP copper solders readily with standard rosin-core or no-clean solder and common flux. For best results, lightly abrade the surface with fine-grit sandpaper before soldering to remove any surface oxidation, then apply flux immediately before heating. Thinner foils (under 0.1 mm) heat very quickly, so use a low-wattage iron and work fast to avoid burning through.
Copper naturally oxidizes when exposed to air and moisture, developing a darkened patina over time. This surface oxidation does not significantly affect bulk electrical or thermal conductivity for most applications. For applications requiring a bright finish or low-resistance surface contact over time, consider applying a thin coat of clear lacquer or storing unused strips in a sealed bag with a desiccant packet.
Yes, 99.9% pure copper is compatible with standard ferric chloride and ammonium persulfate PCB etchants. Thinner foils (0.01 mm – 0.05 mm) are well-suited for hand-cut circuit traces and shielding layers. For full PCB fabrication, you would typically laminate the foil onto a substrate — this copper strip works as raw stock for that process.
Sheet Width is the cross-sectional dimension of the strip (10 mm to 300 mm). Sheet Length is how long the piece runs — either 300 mm, 500 mm, or 1 Meter (1,000 mm). Select the combination that best fits your project footprint. For long runs like bus bars or grounding straps, the 1 Meter length minimizes joins.
No. This is bare copper metal foil with no adhesive. It is raw copper sheet stock intended for mechanical, electrical, or thermal applications where you need solid metal — not a tape product. If you need adhesive-backed copper tape for shielding or crafts, that is a different product category.
Yes. Thinner foils (up to ~0.2 mm) cut cleanly with sharp scissors, a craft knife, or a rotary cutter on a cutting mat. Thicker strips (0.3 mm and above) are best cut with metal snips, a guillotine shear, or a nibbler tool. Always deburr cut edges with fine sandpaper or a deburring tool before handling to avoid sharp edges.
