When your project demands a conductor that won't let you down — whether you're shielding an electronics enclosure, lining a roofing joint, or cutting custom gaskets — finding a copper strip in exactly the right thickness and width is half the battle. This 1-meter pure copper (Cu) sheet strip is stocked in an extensive range of thicknesses (0.02 mm to 1 mm) and widths (10 mm to 400 mm), giving makers, electricians, jewellers, and fabricators the precise blank they need without over-ordering.
Each strip is cut from pure copper flat stock with a bright, uncoated finish. Thickness options span 0.02 mm – 1 mm (approximately 0.0008 in – 0.039 in); width options run from 10 mm – 400 mm (approximately 0.39 in – 15.75 in); and every piece is supplied at a fixed 1,000 mm (39.4 in / ~3.28 ft) length. The material is soft-annealed, making it easy to bend, cut, solder, and form without cracking.
Typical applications include EMI/RF shielding tape for electronics enclosures, grounding straps and bus bars in electrical panels, decorative inlay strips for woodworking and furniture, roofing flashing and expansion joint liners, and custom gaskets or heat-spreader shims in thermal management assemblies — all scenarios where a pure-copper thin foil plate cut to a precise width is essential.

For EMI/RF shielding and laminating applications, ultra-thin grades of 0.02 mm – 0.1 mm are typically sufficient. For gaskets, decorative inlays, and roofing flashing, 0.15 mm – 0.5 mm offers a good balance of formability and durability. For electrical bus bars, grounding straps, or structural applications requiring rigidity, choose 0.6 mm – 1 mm. If you are unsure, contact us to confirm the best grade for your specific load or conductivity requirement.
Select the width closest to your finished part dimension to minimise waste. Narrow strips (10 mm – 30 mm) suit fine inlay work, grounding straps, and narrow shielding tape. Mid-range widths (40 mm – 100 mm) cover most gasket and flashing applications. Wide strips (120 mm – 400 mm) are suited to large shielding panels, heat spreaders, and sheet-metal blanks. All widths are supplied at 1,000 mm length.
This is pure copper (Cu) flat stock — not brass (Cu-Zn) or bronze (Cu-Sn). Pure copper delivers the highest electrical conductivity and thermal conductivity of any common copper-family metal, making it the correct choice for electrical and thermal management applications where alloy substitutes would underperform.
Yes. Pure copper solders and brazes readily with standard copper-rated flux and solder (e.g., 60/40 tin-lead or lead-free SAC305). The bright uncoated surface requires no pre-treatment beyond light cleaning with isopropyl alcohol or flux. For brazing, use a copper or silver-based brazing alloy with an appropriate flux.
Copper naturally oxidises when exposed to air and moisture, developing a patina that progresses from golden-brown to dark brown and eventually verdigris (green). For indoor electrical and shielding applications this surface oxide does not significantly affect performance. For outdoor or high-humidity environments, consider applying a clear lacquer, wax, or conformal coating after installation to slow tarnishing.
Yes. Thin grades (up to ~0.3 mm) can be cut cleanly with heavy-duty scissors or a craft knife and steel rule. Mid-range grades (0.3 mm – 0.6 mm) are best cut with tin snips or a guillotine shear. Thicker grades (0.8 mm – 1 mm) are most cleanly cut with a metal-cutting bandsaw, angle grinder with a thin cutting disc, or a bench shear. Deburr cut edges with a fine file or sandpaper before handling.
Yes. Copper sheet strip is a traditional and durable material for roofing flashing, valley liners, and expansion joint covers. For most residential flashing applications, 0.3 mm – 0.5 mm thickness and widths of 100 mm – 300 mm are commonly specified. Always verify local building codes and roofing standards for minimum thickness requirements in your region.
This product is bare copper flat stock with no adhesive. It is intended for applications where the copper is mechanically fastened, soldered, brazed, or formed into shape. Adhesive-backed copper tape is a separate product category suited for quick-stick shielding or decorative applications. If you need adhesive backing, this product is not the right choice.
