When your project demands a conductor that won't let you down — whether you're wiring a busbar, fabricating a heat sink, or crafting a decorative inlay — finding copper stock cut to the exact size you need is half the battle. This T2 copper flat bar, sheet, and strip range is designed for engineers, makers, and tradespeople who need dimensional accuracy without the waste of cutting oversized stock themselves.
Each piece is cut from T2 (C11000-equivalent) electrolytic tough pitch copper, offering ≥99.9% copper purity. Available widths run from 5 mm (≈0.20 in) to 50 mm (≈1.97 in), lengths from 100 mm (≈3.94 in) to 500 mm (≈19.69 in), and thickness from 0.5 mm (≈0.020 in) up to 60 mm (≈2.36 in). Select your exact combination from the variant options above.
Typical applications include electrical busbars and grounding straps, RF shielding and EMI gaskets, jewellery and metalwork fabrication, heat-transfer components in DIY cooling systems, and architectural or decorative inlay work where a warm copper tone is required.

For low-current busbars (under 50 A), 2–5 mm thickness is typically sufficient. For higher-current runs (50–200 A), 6–15 mm is more common. Always calculate the required cross-sectional area based on your target current density (typically 1–3 A/mm² for copper busbars) and derate for ambient temperature. If you are unsure, contact us to confirm before ordering.
T2 is the Chinese national standard designation for electrolytic tough pitch copper, which is functionally equivalent to ASTM C11000 (C110/ETP). Both specify ≥99.9% copper purity and offer near-identical electrical and thermal conductivity. They are interchangeable in most engineering applications.
Copper naturally forms a thin oxide layer (patina) when exposed to air and moisture. For electrical connections, clean the contact surface with fine abrasive or flux before soldering. For decorative use, apply a clear lacquer or wax coating to preserve the bright finish. For outdoor or humid environments, consider a tin-plating or nickel-plating post-process.
T2 copper in the annealed or half-hard condition bends readily. Thinner strips (0.5–5 mm) can typically be bent cold to a radius equal to 1–2× the thickness without cracking. Thicker bars (10 mm and above) may require annealing (heat to ~400–500 °C and quench in water) before bending to avoid cracking. Always bend across the rolling direction where possible.
Copper and aluminium form a galvanic couple that can cause accelerated corrosion of the aluminium in wet or humid environments. Use bi-metallic transition washers or apply an anti-oxidant compound at the joint. Copper-to-steel contact is less problematic but still benefits from a protective coating or isolation in corrosive environments.
Use the Width × Length dropdown to select the flat dimensions of the piece, then use the Thickness dropdown to select the depth. For example, a 25 mm × 500 mm piece with 3 mm thickness gives you a cross-section of 25 × 3 mm and a 500 mm length. If you need a size not listed, contact us — custom cuts may be available.
Yes. T2 copper's warm reddish tone and workability make it popular for jewellery, architectural inlays, and decorative panels. Thinner gauges (0.5–2 mm) are easiest to cut, pierce, and form by hand. The surface can be polished to a mirror finish, chemically patinated to green or brown tones, or textured with standard metalworking tools.
