T2 Pure Copper Strip — Precision-Cut Foil Sheet for Electronics, Crafts & Model Making
Whether you're winding transformer coils, fabricating custom gaskets, or building intricate scale models, sourcing a reliable copper strip that holds tight tolerances is a constant challenge. This T2 pure copper strip is designed for makers, hobbyists, and small-workshop engineers who need consistent conductivity, clean edges, and a wide range of dimensions in a single product.
Each strip is cut from T2 (C11000-equivalent) electrolytic tough-pitch copper, offering ≥99.9% copper purity. Dimensions follow a Width × 1000mm Length × Thickness format, with widths spanning 5 mm to 120 mm (approx. 0.2" to 4.7") and thicknesses from 0.1 mm to 1 mm (approx. 0.004" to 0.039"). Surface finish is bright-rolled mill finish with no burrs on cut edges.
Common use cases include RF shielding tape, battery tab welding strips, copper inlay craft work, architectural model detailing, and DIY coil-winding projects. Long-tail search terms this product covers: thin copper foil strip roll, pure copper shim stock, copper sheet metal for electronics, copper strip for transformer winding.
✅ Compatible with soldering, brazing, cold-forming, and chemical etching processes. Suitable for use in electronics, HVAC, jewelry, and precision model-making applications.
✅ Key Features of These T2 Pure Copper Strips
🔩
≥99.9% T2 Copper Purity — Electrolytic tough-pitch grade ensures excellent electrical conductivity (≥57 MS/m) and thermal conductivity for coil winding and shielding applications.
📐
Wide Size Range — Width 5–120 mm, thickness 0.1–1 mm, fixed 1000 mm length. Select the exact cross-section you need from the variant options above.
✂️
Clean Mill-Rolled Edges — Bright-rolled surface with no burrs; ready for immediate use in precision assemblies without secondary deburring.
🔧
Excellent Formability — Soft-annealed temper allows bending, stamping, and coiling without cracking, even at tight radii for thin gauges.
⚡
Low Electrical Resistance — Ideal for bus bars, battery interconnects, and transformer secondary windings where resistive losses must be minimised.
🛡️
Natural Corrosion Resistance — Copper's inherent oxidation resistance makes these strips suitable for long-term indoor and moderate-humidity environments without coating.

❓ Frequently Asked Questions
How do I choose the right width and thickness?
Select width based on your coil winding bobbin width or the shielding area you need to cover. Choose thickness based on the current-carrying requirement or mechanical rigidity needed — thinner strips (0.1–0.2 mm) suit foil coils and shielding tape, while thicker strips (0.5–1 mm) are better for bus bars and structural shims.
Is this copper strip suitable for transformer coil winding?
Yes. T2 copper's high conductivity (≥98% IACS) and soft-annealed temper make it a standard choice for foil-wound transformer secondaries. The 1000 mm length per piece is suitable for small to medium coil forms; multiple pieces can be joined with solder or conductive tape.
Will this copper strip corrode or tarnish?
Copper naturally develops a patina (oxidation layer) over time when exposed to air and humidity. This surface tarnish does not significantly affect electrical conductivity for most applications. For bright appearance, store in a dry, sealed environment or apply a clear lacquer after use.
Can I solder or braze this copper strip?
Yes. T2 copper solders and brazes readily with standard rosin-core or water-soluble flux solders. For brazing, use a silver-bearing brazing alloy with appropriate flux. Clean the surface with isopropyl alcohol before soldering for best results.
Is this compatible with chemical etching for PCB or art projects?
Yes. T2 copper etches cleanly with ferric chloride (FeCl₃) or ammonium persulfate solutions commonly used in PCB fabrication and decorative etching. Thinner gauges (0.1–0.2 mm) are easiest to etch through completely.
What is the difference between T2 copper and other copper grades?
T2 (equivalent to C11000 ETP copper) contains ≥99.9% copper and is the most common electrical-grade copper. It offers the best balance of conductivity, formability, and cost. Grades like C10100 (OFE) have slightly higher purity but are rarely needed for general DIY or model-making applications.
Can I cut this strip to a shorter length?
Yes. Thin copper strips (≤0.3 mm) can be cut with sharp scissors or a craft knife and steel ruler. Thicker strips (0.4–1 mm) are best cut with metal shears or a guillotine cutter. Always deburr cut edges with fine sandpaper for safe handling.
