Finding flat copper stock cut to a usable size without ordering a full sheet is a common frustration for hobbyists, electricians, and small-shop fabricators. These T2 copper sheet plate offcuts are stocked in a range of ready-to-use dimensions and thicknesses, so you can order exactly what your project calls for — no cutting waste, no minimum sheet commitment.
Each piece is cut from T2 (C11000) commercially pure copper, offering excellent electrical conductivity and natural corrosion resistance. Plate sizes range from 35×50 mm (approx. 1.4"×2") up to 100×200 mm (approx. 3.9"×7.9"), with thickness options spanning 0.5 mm to 5 mm (approx. 0.02" to 0.20"). Quantity options of 1, 2, or 4 pieces per order let you match your exact needs.
Typical applications include DIY electrical bus bars and grounding straps, custom heat-sink shims for electronics repair, decorative metalwork and etching projects, and small-batch fabrication of gaskets or spacers in light engineering workshops.

Measure the footprint your project requires and select the next size up. For example, if you need a 45×90 mm piece, the 55×100 mm option gives you a small margin for trimming. All dimensions are listed as Width × Length in millimeters.
For light-duty grounding straps and small bus bars, 1–2 mm thickness is typically sufficient. For higher-current applications or structural bus bars, 3–5 mm provides greater cross-sectional area and mechanical rigidity. Always verify current-carrying requirements against your specific circuit design.
Yes. T2 is the Chinese national standard designation that corresponds closely to C11000 ETP copper under ASTM standards. Both refer to commercially pure copper with a minimum copper content of 99.9%, offering excellent conductivity and formability.
Yes. T2 copper solders and brazes readily using standard copper-compatible flux and filler materials. For soft soldering, use a rosin or water-soluble flux with 60/40 or lead-free solder. For brazing, use a silver-bearing brazing alloy with an appropriate flux at temperatures above 450 °C.
Copper naturally oxidizes when exposed to air and moisture, developing a brown or green patina. This patina is stable and actually protects the underlying metal from further corrosion. For applications requiring a bright finish, the surface can be polished and sealed with a clear lacquer.
Yes. Thinner plates (0.5–2 mm) can be cut with tin snips, aviation shears, or a guillotine. Thicker plates (3–5 mm) are best cut with a hacksaw, angle grinder, or band saw fitted with a metal-cutting blade. Drilling is straightforward with standard HSS drill bits — use a slow speed and cutting fluid to extend bit life.
Absolutely. The mill-finish surface accepts etching, stamping, patination chemicals, and cold-forming well. Thinner gauges (0.5–1.5 mm) are particularly popular for jewelry-making, embossing, and decorative panel work.
