When your project demands reliable electrical conductivity and corrosion resistance in a flat metal form, finding a copper sheet cut to the exact dimensions you need can be a frustrating search. Whether you are a hobbyist building custom bus bars, an engineer prototyping heat spreaders, or a craftsperson working on decorative metalwork, this T2 pure copper sheet plate delivers the dimensional accuracy and material purity your work requires.
Each piece is made from T2-grade pure copper (≥99.9% Cu), known for its outstanding electrical and thermal conductivity. Sheets are available in thicknesses of 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 5mm, 6mm, and 8mm (approximately 0.08 in to 0.31 in), with flat dimensions ranging from 50×100mm (approx. 2"×4") up to 300×300mm (approx. 12"×12"). Edges are laser-cut for clean, straight lines with minimal burring.
Typical use cases include DIY electrical bus bars and grounding straps, custom heat spreaders and thermal interface components for electronics cooling, and decorative or artistic metalwork such as etching blanks, jewelry bases, and architectural accents — all applications where the long-tail search term "laser-cut copper plate custom size" leads buyers to exactly this product.

Thinner sheets (2mm–3mm) are well-suited for flexible bus bars, shims, and decorative applications where weight and formability matter. Mid-range thicknesses (3.5mm–5mm) work well for rigid bus bars, grounding plates, and heat spreaders. Thicker sheets (6mm–8mm) are typically used for heavy-duty electrical contacts, machined blanks, and structural copper components. If you are unsure, consider the current-carrying capacity or mechanical load your application requires and select accordingly.
T2 pure copper is relatively soft compared to copper alloys such as brass or bronze, with a tensile strength typically in the range of 200–250 MPa. It is not recommended for high-stress structural applications. However, for electrical bus bars, heat spreaders, and decorative metalwork, the mechanical properties are generally adequate. For applications requiring higher strength, consider a copper alloy instead.
Pure copper naturally oxidizes when exposed to air and moisture, developing a darkened surface or eventually a green patina (verdigris). This surface layer actually slows further corrosion. For electrical connections, it is advisable to clean contact surfaces before assembly or apply a suitable anti-oxidation compound. For decorative use, the patina is often considered desirable. If a bright finish is required long-term, a clear lacquer coating can be applied.
Yes. T2 pure copper has excellent solderability and brazability. Standard lead-free or leaded solders work well for electrical connections. For higher-temperature joints, silver brazing alloys are commonly used. Ensure the surface is clean and free of oxidation before soldering for the best results. Flux appropriate for copper should be used to prevent re-oxidation during the process.
Laser-cut edges are generally cleaner and less sharp than shear-cut edges, but copper edges can still be sharp enough to cause cuts, especially on thicker pieces. We recommend wearing gloves when handling sheets, particularly larger or thicker variants. Light deburring with fine sandpaper or a file can be done if a completely smooth edge is required for your application.
The quantity options refer to the number of individual copper sheet pieces included in a single order at the selected size and thickness. Ordering 2 or 5 pieces typically offers a lower per-piece cost compared to ordering multiple single-piece quantities separately. Choose the quantity that matches your project needs — a single piece for prototyping, or multiple pieces for production runs or stock.
Yes. T2 pure copper is one of the most thermally conductive common metals, making these sheets well-suited for custom heat spreaders, vapor chamber bases, and thermal interface components. The laser-cut flat sheets can be machined, drilled, or shaped to fit specific cooling assemblies. Thicknesses of 2mm–4mm are most commonly used for this application to balance thermal mass and weight.
