When your project demands reliable conductivity, corrosion resistance, and precise dimensions, finding the right pure copper sheet in the correct thickness and width can be a frustrating search. Whether you are a hobbyist, electrician, jeweler, or maker, these pure copper sheet rolls give you the exact gauge and cut you need without ordering oversized stock or paying for custom fabrication.
Each roll is made from 99%+ pure copper, available in thicknesses ranging from 0.1 mm to 0.8 mm (approximately 0.004 in to 0.031 in) and widths from 10 mm to 50 mm (approximately 0.39 in to 1.97 in). Every roll is 1 meter (approximately 39.4 in) in length, providing a workable length for most bench-scale and field applications. The surface is smooth-rolled with consistent thickness tolerance across the full length.
Typical use cases include EMF/RF shielding tape for electronics enclosures, grounding straps in electrical panels and automotive wiring, decorative inlay work in woodworking and leathercraft, and heat-spreading shims in PC modding and thermal management projects. The combination of thin gauge and roll format makes these copper sheets ideal for DIY copper foil shielding, copper strip grounding, and copper tape crafts.
Choose from 7 thickness options (0.1, 0.2, 0.3, 0.5, 0.8 mm) paired with widths of 10, 20, 30, 40, or 50 mm — all in 1-meter rolls — so you get exactly the cross-section your project requires.
Made from 99%+ pure copper, these sheets deliver low electrical resistance, making them reliable for grounding straps, bus bars, and EMF shielding applications.
Copper forms a stable oxide layer over time that slows further corrosion, making these rolls suitable for both indoor and moderately humid outdoor environments without additional coating.
The annealed-soft temper allows clean cutting with scissors or tin snips and easy bending by hand, reducing the need for specialized metalworking equipment.
Pure copper bonds readily with standard rosin-core solder and silver brazing alloys, enabling secure electrical and mechanical joints without flux compatibility issues.
Smooth-rolled to maintain uniform thickness across the full 1-meter length, ensuring predictable performance whether you are stacking shims, wrapping cores, or cutting precise strips.

For EMF/RF shielding and foil wrapping, 0.1–0.2 mm is typically sufficient and easy to conform around irregular surfaces. For grounding straps and bus bars where mechanical strength matters, 0.3–0.5 mm offers a better balance of flexibility and rigidity. For heat-spreading shims or structural applications, 0.5–0.8 mm provides the stiffness needed. Select your thickness from the variant options above.
Width selection depends on the contact area or channel you need to fill. For narrow PCB traces or inlay grooves, 10–20 mm works well. For grounding straps connecting chassis components, 30–50 mm provides lower impedance and better current-carrying capacity. Measure your target surface before selecting.
These rolls are made from 99%+ pure copper, not a brass or bronze alloy. Pure copper offers the highest electrical and thermal conductivity of any common copper product, which is why it is preferred for electrical grounding, shielding, and thermal management applications.
Copper naturally oxidizes and develops a patina (darkening or eventual green verdigris) when exposed to air and moisture. This oxide layer is stable and actually slows further corrosion. For applications where appearance matters, you can apply a clear lacquer or wax coating. For electrical applications, the oxide layer has negligible impact on conductivity at the contact points when properly terminated.
Yes. Pure copper solders readily with standard rosin-core or no-clean solder using a soldering iron. For best results, lightly abrade the surface with fine sandpaper or a fiberglass pen to remove any surface oxide before soldering, then apply flux. Silver brazing is also compatible for higher-temperature joints.
The 0.1–0.3 mm variants can be cut cleanly with heavy-duty scissors or craft scissors. The 0.5 mm and 0.8 mm variants are better suited to tin snips, aviation shears, or a rotary cutter with a metal-cutting blade. Scoring with a utility knife and snapping along a straight edge also works for straight cuts on thinner gauges.
Yes. Pure copper is one of the most effective materials for EMF and RF shielding due to its high electrical conductivity. The 0.1–0.2 mm thickness is commonly used for shielding enclosures, wrapping cables, and lining project boxes. For best shielding effectiveness, ensure all seams are soldered or overlapped and the shield is properly grounded.
