When your project demands reliable electrical conductivity, thermal transfer, or a workable flat metal substrate, finding a copper sheet cut to the exact size you need can be a real challenge. Whether you are a maker, electronics hobbyist, HVAC technician, or small-shop fabricator, sourcing T2 pure copper plate in the right thickness and dimensions without ordering oversized stock saves both time and material cost.
This T2 pure copper plate/sheet is composed of 99.9%+ electrolytic copper (T2 grade), offering outstanding electrical and thermal conductivity. Thickness options span 0.5 mm to 6 mm (approximately 0.020" to 0.236"), and flat dimensions range from 50 × 50 mm (approx. 2" × 2") up to 500 × 500 mm (approx. 19.7" × 19.7"), with rectangular and square formats available. Edges are laser-cut for clean, straight lines and consistent tolerances across the sheet.
Typical applications include custom bus bars and grounding straps for electrical panels, heat spreader shims between CPU/GPU dies and coolers, RF shielding inserts in enclosures, decorative inlay work in woodworking and knife-making, and gasket blanks for low-pressure fluid systems. Long-tail use cases such as "thin copper shim for thermal interface" and "flat copper blank for jewelry stamping" are well served by the thinner 0.5–1 mm variants, while the 3–6 mm range suits structural copper block applications.
T2 Grade Copper (99.9%+ Purity)
Electrolytic-grade T2 copper delivers low electrical resistivity (typically ~1.72 × 10⁻⁸ Ω·m) and high thermal conductivity (~390 W/m·K), making it suitable for demanding electrical and thermal management tasks.
Wide Thickness Range: 0.5 mm – 6 mm
Choose from ultra-thin 0.5 mm shim stock up to a solid 6 mm copper block plate. Thickness increments (0.5, 0.6, 0.8, 1, 1.2, 1.5, 2, 2.5, 3, 4, 5, 6 mm) cover the majority of fabrication needs without custom ordering.
Laser-Cut Edges for Consistent Dimensions
Each piece is laser-cut to size, producing straight, burr-minimized edges and repeatable dimensions. This reduces secondary finishing time compared to shear-cut or hand-sawn copper stock.
Flat Sheet Format — No Coil Curl
Supplied as flat plate rather than coil or roll stock, so thinner gauges (0.5–1.5 mm) arrive without the springback and curl that complicate layout and assembly work.
Multiple Pack Quantities Available
Select 1 PCS, 2 PCS, or 4 PCS per order depending on your project volume. Smaller packs suit prototyping; multi-piece packs offer better per-unit value for production runs.
Machinable, Solderable, and Formable
T2 copper responds well to drilling, milling, bending, and soldering with standard tools and copper-rated consumables. Thinner variants (≤1.5 mm) can be cut with heavy-duty shears or a rotary tool.

For thermal interface shims (CPU/GPU) or flexible electrical straps, 0.5–1 mm is typically sufficient. For bus bars, grounding plates, and structural brackets, 1.5–3 mm provides a good balance of rigidity and workability. For heavy-duty copper block applications such as electrode blanks or EDM work, 4–6 mm is recommended. If you are unsure, start with 1 mm — it is the most versatile thickness for general fabrication.
T2 copper in the annealed state has a tensile strength of approximately 200–250 MPa, which is adequate for light structural brackets, clamps, and spacers. It is not a high-strength alloy — for load-bearing applications requiring greater strength, consider brass or bronze. However, for electrical and thermal structural parts where conductivity is the primary requirement, T2 copper performs well.
Bare copper naturally oxidizes when exposed to air and moisture, forming a patina (cupric oxide) that progresses from bright orange to brown and eventually green (verdigris) over time. For electrical contacts, this surface oxide can increase contact resistance — applying a thin coat of contact grease or tinning the surface with solder will prevent this. For decorative or outdoor applications, a clear lacquer or wax coating is recommended. In dry indoor environments, oxidation is slow and typically does not affect performance for years.
Yes. T2 copper solders readily with standard rosin-core or water-soluble flux and common tin-lead or lead-free solder alloys (e.g., Sn63Pb37, SAC305). For brazing, use a copper-phosphorus or silver-bearing brazing alloy with appropriate flux. The bare surface should be lightly abraded or cleaned with isopropyl alcohol before soldering to remove any surface oxide for best results.
Sheets up to 1.5 mm thick can be cut with heavy-duty aviation snips, a rotary tool with a cutting disc, or a fine-tooth metal-cutting blade. Thicker plates (2 mm and above) are best cut with a bandsaw, jigsaw with a metal blade, or milled on a CNC router. Copper is a soft, ductile metal — use sharp tooling and moderate feed rates to avoid work-hardening and galling. Drilling is straightforward with standard HSS drill bits; use a center punch to prevent wandering.
For desktop CPUs (Intel LGA or AMD AM platforms), a 50 × 50 mm or 50 × 100 mm piece at 0.5–1 mm thickness is typically sufficient to cover the IHS (integrated heat spreader) area. For laptop CPUs and GPUs, 50 × 50 mm at 0.5 mm is a common choice. Always measure your specific die or IHS dimensions before ordering. The 0.5 mm and 0.6 mm variants are the most popular for thermal interface shim applications.
The 1 PCS option is ideal for one-off prototypes or single repairs. The 2 PCS pack suits projects where you want a spare or are building a matched pair (e.g., two bus bar sections). The 4 PCS pack offers the best per-unit value for small production runs, classroom projects, or when you anticipate needing multiple pieces of the same size. Note that not all size/thickness combinations are available in every pack quantity — check the variant selector for available combinations.
