When your project demands reliable electrical conductivity and dimensional accuracy, standard sheet metal simply won't do. Engineers, hobbyists, and electronics makers who need a dependable conductive substrate — whether for grounding pads, bus bars, RF shielding, or custom fabrication — require a material that performs consistently across every cut. These T2 pure copper sheet metal plates are designed for exactly that use case, delivering repeatable results from the smallest 10×10mm tile to the largest 300×300mm panel.
Each plate is made from T2-grade (99.9%+ purity) electrolytic copper, laser-cut to precise dimensions. Thickness options span 0.1mm to 5mm (approximately 0.004 in to 0.197 in), and planar dimensions range from 10×10mm (0.39×0.39 in) up to 300×300mm (11.8×11.8 in). The surface presents a characteristic bright copper finish with no burrs on laser-cut edges.
Typical use cases include DIY electrical grounding strips for home automation panels, custom RF shielding inserts for enclosures, heat-spreader shims between components in electronics repair, and decorative metalwork inlays for woodworking or jewelry projects requiring a conductive copper sheet cut to size.
Electrolytic-grade T2 copper ensures low electrical resistivity (typically ~1.72 µΩ·cm) and excellent thermal conductivity, making these plates ideal for grounding, bussing, and heat-spreading tasks.
Each plate is laser-cut for clean, burr-free edges and tight dimensional tolerances, eliminating the need for secondary deburring and ensuring consistent fit in precision assemblies.
Available from 10×10mm to 300×300mm in planar dimensions, and from 0.1mm to 5mm in thickness, covering ultra-thin foil-like sheets through structural copper plate in a single product line.
Copper forms a stable oxide patina over time that slows further corrosion, making these plates suitable for indoor electrical enclosures, moderate-humidity environments, and long-term embedded applications.
With thermal conductivity of approximately 385–400 W/(m·K), these copper sheets serve effectively as heat spreaders and thermal interface shims between components in electronics and power systems.
Order as a single piece (1 Pcs) or in multi-packs (2 Pcs or 4 Pcs) depending on your project needs, with consistent quality across every piece in the pack.

For flexible grounding straps or foil-style shielding, choose 0.1mm–0.3mm. For rigid bus bars or structural shims, 0.5mm–2mm is typical. For heavy-duty thermal spreaders or machined parts, 3mm–5mm provides the necessary rigidity. If you are unsure, select the variant options above to compare dimensions and pricing.
T2 is the Chinese national standard designation for electrolytic tough-pitch (ETP) copper, which closely corresponds to C11000 in the ASTM/UNS system. Both specify 99.9%+ copper purity and similar electrical and thermal properties, so T2 copper is functionally equivalent for most electrical and thermal applications.
Copper naturally oxidizes to form a brownish or greenish patina (cupric oxide / verdigris) when exposed to air and moisture. This patina is stable and actually slows further corrosion. For applications requiring a bright finish, apply a clear lacquer or store in a sealed bag. For electrical contact surfaces, light sanding or flux application before soldering restores conductivity.
Yes. T2 pure copper is highly solderable with standard rosin-core or no-clean solder and common fluxes. For best results, clean the surface with isopropyl alcohol before soldering to remove any oxidation or handling oils. Thinner sheets (0.1mm–0.5mm) heat up quickly, so use a temperature-controlled iron to avoid warping.
Yes. T2 copper is machinable with standard carbide tooling. It can be drilled, milled, punched, or further laser-cut. Note that copper's ductility means it tends to gum up high-speed steel (HSS) tools; carbide or coated tooling with appropriate cutting speeds is recommended for clean results.
Measure the interior panel dimensions of your enclosure and select the closest available size at or above your required dimensions. For most DIY RF shielding projects (e.g., Faraday cages, filter boxes), 0.3mm–1mm thickness provides adequate shielding effectiveness at HF through VHF frequencies. Thicker plates offer marginally better low-frequency magnetic shielding.
The pack quantity is the second variant dimension (Amount). Select 1 Pcs for single-panel projects or prototyping. Choose 2 Pcs or 4 Pcs for multi-panel builds, redundancy stock, or when you need matching pieces for symmetrical assemblies. Pricing per piece is consistent across pack sizes for the same dimensions.
