When your project demands reliable electrical conductivity and clean, precise dimensions, generic metal stock simply won't cut it. Makers, electricians, jewelers, and hobbyists who need a consistent, ready-to-use copper flat bar will find this T2 pure copper plate an ideal solution — no additional cutting or finishing required.
This T2 pure copper plate/sheet is supplied as a flat bar measuring 275mm × 10mm × 1mm (approximately 10.83" × 0.39" × 0.04"). T2 grade copper offers ≥99.9% copper purity, delivering excellent electrical and thermal conductivity. The laser-cut edges are clean and burr-free, ready for immediate use in your application.
Typical use cases include DIY electrical bus bars and grounding straps, custom copper shims and spacers for mechanical assemblies, jewelry making and metalworking craft projects requiring a T2 pure copper laser cut flat bar with precise dimensions.
T2 designation ensures copper purity of 99.9% or higher, providing excellent electrical conductivity (IACS ≥97%) and thermal conductivity for demanding applications.
Each piece is laser cut to exact 275mm × 10mm × 1mm dimensions with clean, burr-free edges — no secondary deburring or trimming needed before use.
Uniform 1mm thickness across the full 275mm length ensures reliable fit in tight-tolerance assemblies, shim stacks, and layered electrical connections.
T2 copper is soft and ductile, making it easy to bend, drill, solder, or braze without cracking — suitable for both cold-forming and heat-joining techniques.
Copper naturally forms a protective patina over time, resisting oxidation in typical indoor and light outdoor environments without additional coating.
At just 1mm thick and 10mm wide, this flat bar is easy to store, handle, and integrate into compact assemblies, PCB grounding, or decorative metalwork.

T2 is a copper grade designation indicating a minimum purity of 99.9% copper content. This level of purity ensures excellent electrical conductivity (≥97% IACS) and thermal conductivity, making it suitable for electrical bus bars, grounding connections, and heat-transfer applications where impurities would reduce performance.
Yes. T2 pure copper's high conductivity makes it well-suited for DIY grounding straps, bus bars, and electrical connection strips. Ensure the dimensions (275mm × 10mm × 1mm) meet your current-carrying requirements and consult applicable electrical codes for your installation.
Yes. T2 copper is highly compatible with standard tin-lead and lead-free solders, as well as silver brazing alloys. Clean the surface with flux before soldering for best adhesion. The material's ductility also allows cold-forming and bending without cracking.
Copper does not rust (rust is iron oxide). Over time, copper naturally develops a patina — first darkening to brown, then potentially forming a green verdigris in humid or outdoor environments. For indoor electrical and mechanical use, this patina is generally harmless and does not significantly affect conductivity. Apply a clear lacquer if you want to preserve the bright copper appearance.
This listing is for the 275mm × 10mm × 1mm size. If you need a different length, width, or thickness, please check our other copper flat bar listings or contact us — we carry a range of T2 copper sheet and strip sizes to suit various project requirements.
Copper can be used alongside aluminum or stainless steel, but direct contact between dissimilar metals in wet environments can cause galvanic corrosion. Use appropriate isolation tape, gaskets, or coatings when joining copper to aluminum in outdoor or high-humidity applications. In dry indoor environments, direct contact is generally acceptable for short-term use.
Absolutely. T2 pure copper's warm color, workability, and ductility make it a popular choice for jewelry, art installations, and decorative inlays. It can be cut with metal shears, filed, sanded, and polished to a mirror finish. The laser-cut edges provide a clean starting point for further shaping.
