When your project demands reliable conductivity and consistent gauge, generic metal stock falls short. Engineers, hobbyists, and small-shop fabricators working on PCB shielding, heat spreaders, gaskets, and custom metalwork need copper they can trust down to the hundredth of a millimeter. This T2 pure copper sheet foil delivers exactly that — verified 99.9% purity with tightly controlled thickness so every cut behaves predictably.
Each sheet is composed of T2-grade electrolytic copper, offering a smooth, burr-minimized surface finish. Thickness ranges from 0.01 mm (≈ 0.0004 in) up to 1 mm (≈ 0.039 in), and width options span 15 mm (≈ 0.59 in) to 400 mm (≈ 15.75 in). Length is available in 1 m and 5 m rolls or strips, giving you the flexibility to order exactly what your build requires.
Typical applications include electromagnetic shielding tape for electronics enclosures, thermal interface layers in LED and power-module assemblies, custom gaskets and washers for plumbing or mechanical joints, and decorative inlay work in woodworking or jewelry. The combination of tight dimensional tolerances and high-purity copper makes this foil a go-to material for precision DIY copper sheet fabrication projects.

For EMI/RF shielding tape and flexible wrapping, 0.01 mm – 0.05 mm foil is typically sufficient. For heat spreader pads and thermal interface layers, 0.1 mm – 0.3 mm provides a good balance of thermal mass and formability. For structural gaskets, bus bars, or stamped contacts, 0.5 mm – 1 mm offers the rigidity needed. Select your thickness above before adding to cart.
Measure the perimeter of your shielding can and add 5–10 mm for overlap. For most small PCB shields, widths of 15 mm – 60 mm are common. For larger enclosures or flat sheet blanking, widths of 100 mm – 400 mm allow you to cut multiple pieces from a single strip, reducing waste.
Yes. T2-grade copper with ≥ 99.9% purity solders and brazes readily with standard flux and filler materials. The low-oxide surface finish minimizes pre-cleaning requirements. For best results with thin foils (under 0.05 mm), use a temperature-controlled iron and avoid prolonged heat exposure to prevent warping.
T2 is the Chinese national standard designation for electrolytic tough-pitch copper, equivalent to C11000 (ETP) in ASTM standards. Both have ≥ 99.9% copper content and nearly identical electrical and thermal conductivity. If your application calls for C110 or ETP copper, T2 is a direct functional equivalent.
Copper naturally oxidizes when exposed to air and moisture, forming a patina that ranges from dull brown to green verdigris. For electrical contacts and shielding applications, this surface oxide can increase contact resistance over time. To slow oxidation, store unused sheets in a sealed bag, apply a thin coat of lacquer, or use tin-plated copper if long-term corrosion resistance is critical.
Thin foils (0.01 mm – 0.1 mm) cut cleanly with sharp scissors or a craft knife and straightedge. Thicker sheets (0.2 mm – 1 mm) are best cut with metal shears, a guillotine cutter, or a CNC laser. Copper reflects CO₂ laser wavelengths, so fiber lasers are recommended for laser cutting. Always deburr cut edges before handling to avoid cuts.
The 5 m option is supplied as a single continuous strip or roll of the selected width and thickness. This is ideal for projects requiring long runs without seams, such as wrapping cables, lining enclosures, or cutting multiple identical pieces from one piece of stock.
