Advantages of Our Copper Strip
Superior Conductivity and Electrochemical Stability
Our copper strips are manufactured from high-purity electrolytic copper (Cu content ≥99.9%), ensuring exceptional electrical conductivity (IACS). This high level of electrical consistency makes them ideal for transformer windings, busbars, and lithium battery connectors, effectively reducing resistance loss, enhancing energy transmission efficiency, and ensuring the long-term operational stability of electronic devices.
Precision Slitting Process and Burr-Free Edges
Utilizing advanced high-precision slitting machines, we provide copper strips with extremely tight width tolerances. Specifically for the transformer industry, we offer round edge or burr-free processing to prevent insulation tearing during winding, reducing the risk of short circuits. Flat profiles and neat coiling ensure smooth decoiling on high-speed automated production lines.
Excellent Deep Stamping Performance and Fabrication Toughness
Our copper strips undergo precise annealing to achieve excellent ductility and fatigue strength. This allows the material to maintain high yield rates without cracking during complex high-speed stamping, bending, or lead frame forming. Whether in O (Soft) or 1/2H (Half-hard) temper, it perfectly matches your fabrication parameters.

FAQs
How is the edge quality of your copper strip? Will it scratch the insulation paper during winding?
We use precision slitting tools to ensure burr-free edges. For transformer winding needs, we can also provide specialized round edge processing. This effectively prevents burrs from tearing the insulation layer and causing short circuits, ensuring the high reliability of transformer operation.
How do you prove that the conductivity of the copper strip meets the T2/C11000 standard?
Our copper strips have a copper content of ≥99.9%. Each batch undergoes eddy current conductivity testing before leaving the factory to ensure conductivity ≥98% IACS. The Mill Test Certificate (MTC) provided with the shipment lists accurate conductivity and chemical composition, meeting the requirements of precision electronics and power equipment.
How do you control the dimensional tolerance of the copper strip during high-speed stamping?
Relying on advanced cold rolling and slitting equipment, our thickness tolerance can be controlled within ±0.005mm, and width tolerance within ±0.05mm. High-precision dimensional consistency significantly reduces stamping die wear and improves the stability of automated continuous production.
My product requires multiple bends; how do I choose the appropriate temper?
If you need excellent bending and elongation performance, we recommend O (Soft) temper; if your parts require structural rigidity, 1/2H (Half-hard) is more suitable. We will recommend the best-matching annealing process based on your bending radius and product shape to ensure no cracking or deformation during stamping.
What coil diameters can you provide? How do you prevent rust during humid sea freight?
We can customize the inner diameter (e.g., 300mm/500mm) and maximum outer diameter according to your equipment requirements. For ocean freight, we use vacuum packaging or VCI paper with desiccants, finally reinforced on wooden pallets to ensure the copper strip remains bright and free of oxidation upon arrival.
