When your project demands reliable electrical conductivity, thermal transfer, or corrosion-resistant shielding, finding a copper sheet that ships in the exact size you need — without costly custom fabrication — is a real challenge. Whether you are a maker, electronics hobbyist, jeweler, or small workshop operator, these T2 copper sheets give you the precise thickness and dimensions to get the job done right the first time.
Each sheet is made from T2-grade copper with 99.9% Cu purity, delivering excellent electrical and thermal conductivity. Available in thicknesses ranging from 0.1 mm (approximately 0.004 in) to 1 mm (approximately 0.039 in), and in flat sheet dimensions from 10×10 mm (0.39×0.39 in) up to 500×500 mm (19.7×19.7 in). Sheets are supplied in quantities of 1, 2, or 4 pieces depending on the selected size variant.
Typical use cases include RF and EMI shielding panels for electronics enclosures, heat spreader pads in DIY thermal management builds, decorative inlay and metalwork for jewelry and craft projects, grounding straps and bus bars in electrical installations, and thin gasket or shimming material in precision mechanical assemblies.

For EMI/RF shielding, thicknesses of 0.1–0.3 mm are typically sufficient for most frequency ranges. For heat spreading or thermal interface applications, 0.3–0.5 mm offers a good balance of conductivity and flexibility. For structural or mechanical shimming, 0.5–1 mm provides more rigidity. If you are unsure, start with 0.5 mm as a versatile mid-range option.
T2 copper is a relatively soft, ductile metal. Thinner sheets (0.1–0.3 mm) are best suited for flexible or conformable applications such as shielding tape, gaskets, or decorative inlay. Thicker sheets (0.5–1 mm) can handle light structural roles such as bus bars, grounding straps, or rigid heat spreaders, but copper is not recommended as a primary load-bearing structural material.
Copper naturally oxidizes when exposed to air and moisture, developing a darkened patina over time. This oxide layer is stable and actually slows further corrosion. For applications requiring a bright finish, you can apply a clear lacquer or anti-tarnish coating. In highly corrosive environments (salt spray, acids), additional protection is recommended.
Yes. T2 copper is highly solderable and brazeable. Use a rosin-based or no-clean flux for electronics soldering, or a copper-compatible brazing flux for higher-temperature joining. Clean the surface with isopropyl alcohol or fine abrasive before soldering to remove any oxide layer for best results.
Copper can be laser cut, though it is reflective and requires a fiber laser rather than a CO₂ laser for reliable results. For CNC milling or routing, use sharp carbide tooling and appropriate cutting speeds to avoid work-hardening. Hand shearing and score-and-snap methods work well for thinner sheets (0.1–0.5 mm).
Use the "Thicknesses X Length X Width" dropdown to select your required thickness and sheet dimensions. The "Quantitys" dropdown lets you choose 1, 2, or 4 pieces per order. Note that larger sheet sizes are typically available in smaller pack quantities (1–2 PCS), while smaller sizes are available in packs of 4. Check the variant options for the exact combination available for your chosen size.
T2 copper (also known as C11000 or ETP copper in some standards) is an electrolytic tough-pitch copper with 99.9% minimum purity. It offers excellent electrical and thermal conductivity, making it the standard choice for electrical and electronic applications. It is softer and more workable than phosphor bronze or beryllium copper, which are used where spring properties or higher strength are needed.
