99.9% Pure Copper Sheet Foil Strip — Precision-Cut for Electronics, Crafts & Model Making
Working with materials that oxidize, corrode, or lack conductivity is a constant frustration for electronics hobbyists, model makers, and DIY fabricators. This 99.9% pure copper (Cu) metal sheet foil strip delivers exceptional electrical conductivity, thermal performance, and corrosion resistance in a ready-to-use flat strip format — ideal for anyone who demands precision and reliability from their raw materials.
Each piece is composed of 99.9% pure T2-grade copper, available in thicknesses ranging from 0.03mm to 0.5mm, with a fixed width of 200mm and length of 1000mm. The ultra-thin foil options (0.03–0.05mm) are suitable for flexible shielding and laminating, while thicker gauges (0.1–0.5mm) suit structural and conductive applications.
Common use cases include EMI/RF shielding panels, grounding straps, battery tab connectors, PCB prototyping, jewelry crafting, architectural model building, and heat-spreading applications in electronics enclosures.
✅ Compatible with soldering, brazing, etching, cutting, bending, and laminating processes. Suitable for electronics, HVAC, jewelry, and precision fabrication workflows.

❓ Frequently Asked Questions
What thickness should I choose for EMI shielding?
For EMI/RF shielding, 0.05mm to 0.1mm is typically sufficient for most frequency ranges. Thinner foils (0.03mm) work for low-frequency shielding when laminated, while 0.1mm+ provides better structural integrity for enclosure lining.
Can this copper sheet be soldered?
Yes. 99.9% pure copper solders very well with standard rosin-core or lead-free solder. Light sanding or flux application improves adhesion on oxidized surfaces. Thinner gauges (0.03–0.1mm) are especially easy to solder for PCB and electronics work.
Is this suitable for battery tab connectors?
Yes. The 0.1mm to 0.2mm thickness range is commonly used for lithium battery tab connectors and bus bars due to the combination of flexibility, conductivity, and mechanical strength.
Will the copper sheet corrode or tarnish?
Copper naturally develops a patina (oxidation layer) over time when exposed to air and moisture. This does not significantly affect conductivity for most applications. For bare-metal appearance, store in a sealed bag or apply a clear lacquer coating.
Can I cut this to custom sizes?
Yes. Thinner gauges (0.03–0.2mm) can be cut with sharp scissors or a craft knife. Thicker gauges (0.3–0.5mm) are best cut with metal shears or a rotary cutter. The material does not require special tools for most hobby and DIY applications.
Is this the same as copper tape or copper foil tape?
No. This is bare copper sheet/foil without any adhesive backing. It is a raw metal material intended for fabrication, not a self-adhesive tape product. If you need adhesive-backed copper, please check our other listings.
What is the difference between 0.03mm and 0.05mm thickness?
The 0.03mm foil is extremely thin and flexible — similar to heavy-duty aluminum foil in feel — and is best for laminating or wrapping applications. The 0.05mm offers slightly more rigidity and is easier to handle for cutting and positioning in shielding or craft projects.
