Finding a reliable, consistent copper strip for electronics shielding, grounding, or craft work is harder than it should be. Thin-gauge copper that kinks, corrodes, or ships in short lengths wastes time and money. This 100M roll of T2 copper foil strip is designed for makers, electronics technicians, jewelers, and workshop professionals who need a long, uninterrupted run of pure copper in a compact, easy-to-handle format.
Each roll is made from T2-grade copper with a purity of 99.9%, delivering excellent electrical conductivity and solderability. The strip measures 10mm (approximately 0.39 in) wide and 0.2mm (approximately 0.008 in) thick, with a total length of 100M (approximately 328 ft) per roll. The thin profile allows it to be cut, bent, and formed without specialized tooling.
Typical applications include EMI/RFI shielding tape for electronics enclosures, grounding straps in electrical panels, decorative inlay work in woodworking and jewelry, heat-spreading layers in DIY thermal management projects, and conductive traces for hobbyist PCB repair and prototyping.

T2 is a designation for commercially pure copper with a minimum purity of 99.9%. It offers excellent electrical conductivity (typically ≥57 MS/m), good thermal conductivity, and reliable solderability — making it the standard choice for electrical and electronics applications where impurities would degrade performance.
T2 copper strip in foil gauges like 0.2mm is typically supplied in a soft-annealed state, which means it is flexible and easy to bend or form by hand. If you need a harder temper for spring-contact applications, please contact us to confirm the available temper options.
Yes. 99.9% pure copper solders readily with standard rosin-core or water-soluble flux and common tin-lead or lead-free solder alloys. For best results, clean the surface with isopropyl alcohol before soldering to remove any surface oxidation.
Bare copper will naturally oxidize and develop a patina when exposed to air and moisture. For applications where surface conductivity must be maintained long-term (e.g., exposed grounding straps), you can tin the surface with solder, apply a clear lacquer, or use conductive copper tape with an adhesive backing over the top. For shielded or enclosed applications, oxidation is generally not a concern.
At 0.2mm thickness, the strip can be cut cleanly with standard household scissors, craft scissors, or metal shears. A steel ruler and a sharp craft knife also work well for straight cuts. No power tools are required for cutting to length.
Yes. Pure copper is one of the most effective materials for electromagnetic interference (EMI) and radio-frequency interference (RFI) shielding due to its high conductivity. The 10mm width is commonly used to line enclosure seams, wrap cables, or create grounding paths in DIY shielding projects.
For grounding straps and EMI shielding, 10mm width is a versatile starting point that fits most standard enclosure seams and cable diameters. For jewelry inlay or decorative work, narrower strips may be preferred. If you need a different width or thickness, check our other copper strip listings or contact us to confirm available dimensions.
