When your project demands reliable electrical conductivity and corrosion resistance in a flat metal form, finding a copper sheet cut to the exact thickness and size you need can be a real challenge. Whether you are a hobbyist building custom bus bars, an engineer fabricating heat spreaders, or a craftsperson working on decorative metalwork, this T2 pure copper plate delivers the dimensional accuracy and material purity your work requires.
Each piece is cut from T2-grade (99.9%+ copper) solid copper stock. Thickness options range from 1.2 mm to 10 mm (approximately 0.047 in to 0.394 in), and flat dimensions span from 10 mm × 10 mm up to 300 mm × 300 mm (roughly 0.39 in × 0.39 in to 11.8 in × 11.8 in). Rectangular cuts such as 50 mm × 100 mm, 100 mm × 200 mm, and 200 mm × 300 mm are also available. Pieces are sold individually or in small multi-packs depending on the selected size.
Typical applications include DIY electrical bus bars and grounding straps, custom heat spreaders and thermal interface shims for electronics cooling, laser-cut copper blanks for jewelry and decorative art, RF shielding plates for amateur radio and electronics enclosures, and replacement wear plates or contact pads in light industrial machinery.

For electrical bus bars and grounding straps, 1.2 mm – 2 mm is typically sufficient for low-current applications, while 3 mm – 6 mm suits higher-current runs. For structural or wear-plate uses, 4 mm – 10 mm provides the rigidity needed. If you are unsure, select a thickness that matches or slightly exceeds the thinnest cross-section required by your design.
T2 is the Chinese national standard designation for electrolytic tough-pitch (ETP) copper, which is broadly equivalent to C11000 (UNS) and CW004A (EN). All three share ≥ 99.9% copper purity and similar conductivity ratings, so T2 plate is a direct functional substitute in most electrical and thermal applications.
Copper naturally develops a thin oxide layer when exposed to air. This patina slows further corrosion but can slightly increase contact resistance at electrical joints. For critical electrical connections, lightly sand or clean the mating surfaces with isopropyl alcohol before assembly, and apply an anti-oxidation compound or tin-plate the contact area if long-term stability is required.
Yes. T2 copper solders readily with standard 60/40 or lead-free solder using rosin or no-clean flux. For higher-strength joints, silver brazing alloys (e.g., 45% silver) work well with a propane or oxy-acetylene torch. Clean the surface thoroughly before soldering to remove any oxide layer for the best bond.
Thin plates (1.2 mm – 2 mm) can be cut with aviation tin snips or a jigsaw fitted with a metal-cutting blade. Thicker plates (3 mm and above) are best handled with an angle grinder, band saw, or CNC router. For drilling, use sharp HSS or cobalt drill bits with cutting oil and a slow feed rate to avoid work-hardening the copper.
Copper is inherently corrosion-resistant and performs well in most outdoor and humid conditions, developing a protective patina over time. For marine or highly acidic environments, consider applying a clear lacquer or wax coating to preserve the appearance and slow patina formation. The structural integrity of the plate is not significantly affected by typical outdoor exposure.
Use the Thickness × Width × Length dropdown to choose your required dimensions. Thickness is listed first (e.g., 2 mm), followed by the two flat dimensions (e.g., 100 mm × 100 mm). If you need a size not listed, contact us — custom cuts may be available for larger orders.
