Finding flat copper stock that is both dimensionally accurate and free of surface contamination is a constant challenge for electronics hobbyists, jewellers, and small-workshop fabricators. This listing offers 99.9% pure copper sheet, plate, foil, and strip in a wide selection of thicknesses and widths, guillotine-cut to a clean, burr-minimised edge so you can work with it straight out of the package.
Each piece is cut from solid copper sheet stock with a thickness range of 0.01 mm (≈ 0.0004 in) up to 1 mm (≈ 0.039 in) and widths from 5 mm (≈ 0.20 in) to 120 mm (≈ 4.72 in). Standard length is 1,000 mm (≈ 39.4 in / 1 m), with a 16,000 mm (16 m) roll option available on select sizes. The material is uncoated, oxygen-free-grade copper with a bright, smooth mill finish.
Typical applications include RF shielding and EMI gaskets for electronics enclosures, bus-bar fabrication and battery tab connections, decorative inlay work and metalsmithing, heat-spreader shims in thermal management assemblies, and thin-foil artwork or etching projects requiring a copper sheet for etching substrate.

For flexible shielding tape, EMI gaskets, or decorative foil work, choose 0.01 mm – 0.1 mm. For bus bars, battery tabs, and electrical connectors, 0.1 mm – 0.5 mm offers a balance of flexibility and current-carrying capacity. For structural brackets, heat spreaders, or machined parts, 0.5 mm – 1 mm provides rigidity. If you are unsure, select the variant options above to compare dimensions and pricing before adding to cart.
Yes. At 99.9% purity, this copper achieves approximately 100% IACS conductivity, making it suitable for bus-bar fabrication and lithium-cell tab welding. For high-current applications, select a thicker gauge (0.2 mm+) and an appropriate width to keep resistive heating within acceptable limits. Always verify current ratings against your specific design requirements.
Copper naturally oxidises when exposed to air and moisture, developing a patina that progresses from bright orange to brown and eventually verdigris green. This surface oxide does not significantly affect bulk conductivity in most applications. To preserve the bright finish, apply a clear lacquer or wax coating. For outdoor or high-humidity environments, consider tinning or plating the surface after cutting.
Yes. The uncoated mill finish accepts standard rosin-core or water-soluble flux and 60/40 or lead-free solder without pre-treatment. For best results, lightly abrade the surface with fine-grit sandpaper or a fibreglass pen to remove any light oxidation before soldering, especially if the material has been stored for an extended period.
Thin foils (0.01 mm – 0.1 mm) cut cleanly with sharp scissors, a craft knife, or a rotary cutter on a cutting mat. Mid-range gauges (0.1 mm – 0.5 mm) are best cut with aviation snips or a bench shear. Thicker stock (0.5 mm – 1 mm) can be cut with a hacksaw, angle grinder with a thin cutting disc, or a metal-rated jigsaw blade. Always deburr cut edges with a file or fine sandpaper before handling.
The 16,000 mm (16 m) length option is currently available on select thickness and width combinations — specifically the 0.25 mm × 15 mm variant shown in this listing. Other sizes are supplied as 1,000 mm (1 m) straight-cut lengths. If you need a longer continuous piece in a different size, please contact us to confirm availability before ordering.
Use the three dropdown menus above the Add to Cart button to choose your Thickness, Width, and Length. The price updates automatically to reflect your selection. If a combination is not available, that option will appear greyed out. For bulk orders or custom cuts outside the listed dimensions, please reach out via the contact page.
