When your project demands reliable conductivity and dimensional accuracy, standard hardware-store metal simply falls short. Whether you are a hobbyist building RF shielding enclosures, an electrician fabricating custom bus bars, or a craftsperson working on decorative metalwork, sourcing the right copper foil in the exact thickness and width you need can be a frustrating experience. This 99.9% pure copper sheet roll is designed for professionals and DIYers who refuse to compromise on material quality.
Each roll is made from 99.9% pure electrolytic copper, delivering excellent electrical conductivity, thermal transfer, and workability. Thickness options range from 0.01 mm to 0.06 mm (approximately 0.0004 in to 0.0024 in), and width options span from 5 mm to 300 mm (approximately 0.2 in to 11.8 in). Available in 1-meter and 5-meter lengths, the foil ships flat-rolled to minimize creasing and maintain dimensional consistency.
Typical use cases include EMI/RFI shielding tape for electronics enclosures, grounding strips in PCB prototyping, decorative inlay work in woodworking and jewelry, heat-spreading layers in DIY thermal management builds, and custom gasket or flashing material in plumbing and HVAC repair projects. The combination of ultra-thin gauge and wide width selection makes this copper foil roll one of the most versatile raw materials for precision DIY metalwork.

For EMI/RFI shielding tape and PCB grounding strips, 0.01–0.02 mm is typically sufficient and easiest to cut and apply. For structural shims, gaskets, or heat-spreading applications where mechanical rigidity matters, 0.04–0.06 mm provides better handling and durability. If you are unsure, 0.03 mm is a versatile mid-range option that balances flexibility with strength.
Measure the channel, groove, or surface you need to cover and add 2–5 mm on each side for overlap or fold-over. For narrow PCB trace shielding, widths of 10–25 mm are common. For full-panel EMI enclosure lining or wide flashing applications, widths of 100–300 mm are more appropriate. All width options are listed in the variant selector above.
At 0.01–0.02 mm, the foil is primarily suited for electrical and decorative uses where mechanical load is minimal. At 0.04–0.06 mm, the material can serve as a shim, gasket, or thin structural layer in low-stress assemblies. For load-bearing structural applications, a thicker copper plate (typically 0.5 mm and above) would be more appropriate.
Copper naturally oxidizes when exposed to air and moisture, developing a characteristic patina (ranging from brown to green over time). This patina is non-destructive and actually provides a degree of corrosion protection. For applications requiring a consistently bright appearance — such as decorative inlay or visible architectural detail — apply a clear lacquer or copper-specific sealant immediately after installation.
Yes. 99.9% pure copper solders readily with standard rosin-core or no-clean flux solder. Lightly abrade or clean the surface with isopropyl alcohol before soldering to remove any surface oxidation. Thinner gauges (0.01–0.02 mm) may require a lower iron temperature and faster dwell time to avoid burning through the foil.
Yes. At all available thicknesses (0.01–0.06 mm), the foil can be cut cleanly with sharp scissors, a craft knife and steel ruler, a rotary cutter, or a die-cutting machine. For very narrow strips, a metal straight-edge and a sharp utility knife on a cutting mat will give the cleanest edge. Avoid tearing, as this can cause irregular edges and micro-cracks.
Both options are the same material and quality. The 1-meter roll is ideal for prototyping, small repairs, or single-use projects. The 5-meter roll offers a lower per-meter cost and is better suited for larger projects, production runs, or situations where you want a continuous length without joins. Select your preferred length in the variant selector above.
