Finding a copper sheet that holds tight dimensional tolerances without warping or surface oxidation is a persistent challenge for electronics engineers, jewellers, and fabricators alike. This T2 99.9% pure copper flat stock is cut to your chosen dimensions so you receive exactly the size you need — no trimming waste, no guesswork.
Each piece is milled from T2-grade electrolytic copper (Cu ≥ 99.9%), offering excellent electrical conductivity (≥ 57 MS/m) and thermal conductivity (~390 W/m·K). Thickness options span 0.5 mm to 10 mm (approx. 0.020" to 0.394"), widths from 10 mm to 300 mm (approx. 0.39" to 11.81"), and lengths from 50 mm to 500 mm (approx. 1.97" to 19.69"). Sheet faces are mill-finished with a smooth, clean surface ready for further processing.
Typical applications include copper bus bar fabrication and electrical grounding straps, heat spreader plates for DIY CPU cooling and power electronics, decorative metalwork such as etched copper panels and jewellery blanks, and RF shielding enclosures for amateur radio and EMC testing projects.

For electrical grounding straps and flexible bus bars, 0.5 mm–1 mm is typically sufficient. For rigid bus bars and structural brackets, 2 mm–4 mm provides the necessary stiffness. Heat spreader plates for power electronics generally use 2 mm–6 mm depending on the thermal load. For heavy-duty fabrication or machined parts, 6 mm–10 mm is recommended. Select your thickness from the variant dropdown above.
Yes. T2-grade copper (Cu ≥ 99.9%) has an electrical conductivity of ≥ 57 MS/m (≥ 98% IACS), which is the standard specification for electrical bus bars and grounding conductors. It is widely used in switchgear, distribution panels, and custom power distribution builds.
Pure copper naturally oxidises when exposed to air and moisture, developing a patina over time. For indoor electrical applications this does not affect conductivity significantly. For decorative or outdoor use, applying a clear lacquer or wax coating after cleaning will slow tarnishing. For corrosion-critical environments, consider tinning or nickel plating the surface.
Yes. T2 copper is highly machinable and ductile. Thin sheets (0.5 mm–2 mm) can be cut with aviation snips, guillotine shears, or a jigsaw with a metal blade. Thicker sheets (3 mm+) are best cut with a band saw, angle grinder, or CNC router. Copper is also laser-cuttable and can be drilled, tapped, and cold-formed without cracking.
T2 is the Chinese national standard designation for electrolytic tough pitch (ETP) copper, which is equivalent to ASTM C11000 (C110) used in North America and CW004A in Europe. All three designations refer to copper with ≥ 99.9% purity and are interchangeable for most electrical and thermal applications.
Use the Thickness X Width X Length (mm) dropdown to choose your exact dimensions, then select the Quantities option (1, 2, or 4 pieces per order). The price shown updates automatically to reflect your selection. If you need a size not listed, contact us via the store chat and we will advise on the closest available option.
Absolutely. T2 pure copper is a popular choice for jewellery blanks, etched decorative panels, and art metalwork because of its warm colour, excellent ductility, and ease of forming. Thinner gauges (0.5 mm–1.5 mm) are ideal for stamping, doming, and wire-wrapping bases, while 2 mm–3 mm sheets work well for engraved or etched plaques.
