When your project demands a metal that combines excellent conductivity, workability, and corrosion resistance, standard hardware store stock rarely delivers the exact thickness you need. Whether you are a hobbyist building custom electronics, a craftsperson working on decorative metalwork, or a technician sourcing shielding material, finding a reliable copper sheet in precise gauges can be frustrating. This red copper sheet roll is designed for makers, engineers, and DIYers who need consistent, ready-to-cut metal foil without minimum order headaches.
Each sheet is made from C11000 electrolytic tough-pitch (ETP) red copper — a commercially pure copper alloy known for its outstanding electrical and thermal conductivity. Sheets are available in two panel sizes: 200×500mm (approximately 7.9×19.7 in) and 200×1000mm (approximately 7.9×39.4 in), with thickness options ranging from 0.03mm to 0.8mm (approximately 0.001–0.031 in). The rolled format ensures flat, consistent material with a smooth surface finish suitable for cutting, forming, and soldering.
Typical use cases include DIY RF and EMI shielding enclosures, custom copper bus bars and electrical contacts, decorative inlay work and jewelry making, heat spreader fabrication for electronics cooling, and arts-and-crafts projects such as etching, embossing, and repoussé. The thin foil gauges (0.03–0.1mm) are especially popular for copper tape shielding and craft applications, while the heavier gauges (0.2–0.8mm) suit structural and thermal transfer tasks.

For EMI/RF shielding and craft applications such as etching or embossing, the thinner gauges (0.03–0.1mm) are easiest to cut and shape by hand. For heat spreaders, bus bars, or structural applications where rigidity matters, choose 0.2mm or thicker. If you need to solder the sheet into a circuit or enclosure, 0.1–0.3mm offers a good balance of workability and mechanical strength.
The thinnest gauges (0.03–0.1mm) can be cut cleanly with sharp craft scissors or a rotary cutter on a cutting mat. For gauges 0.15mm and above, metal shears or tin snips are recommended for clean, straight cuts. A CNC router or laser cutter will produce the most precise results across all thicknesses.
Yes. C11000 ETP copper is one of the most solderable copper alloys. Use a standard rosin-core or water-soluble flux with 60/40 or lead-free solder. Clean the surface with isopropyl alcohol before soldering to remove any surface oxidation for the best joint quality.
Copper naturally oxidizes and develops a patina (darkening or greening) when exposed to air and moisture. This patina is a stable copper oxide layer that actually protects the underlying metal from further corrosion. For applications where appearance matters, apply a clear lacquer or wax coating to preserve the bright copper finish. For electrical applications, the oxide layer has negligible impact on conductivity at contact points.
The 200×500mm panel (approx. 7.9×19.7 in) is ideal for smaller projects, prototypes, or when you need a specific short length. The 200×1000mm panel (approx. 7.9×39.4 in) provides twice the length and is more economical per unit area for larger shielding panels, long bus bars, or multiple smaller pieces cut from a single sheet. Select your preferred size using the Wide×Length variant option above.
Yes. C11000 copper responds well to standard patination chemicals such as liver of sulfur, ferric chloride (for PCB etching), and ammonia fuming. The smooth rolled surface provides an even base for consistent etching results. Always follow appropriate safety precautions when working with chemical etchants.
While this sheet is not a pre-laminated PCB blank (it does not have a fiberglass substrate), the thinner gauges (0.03–0.1mm) can be used for hand-cut circuit traces, copper tape wiring, or as a conductive layer in experimental electronics projects. For traditional PCB etching, you would need to bond the sheet to a substrate or use it as a standalone flexible circuit element.
