Features:

High conductivity: T2 Copper Foil Strip has a conductivity of up to 97% IACS, ensuring current transmission efficiency. (Buyers who buy our products usually use them on circuit boards or dry-type transformers)
Excellent thermal conductivity: The thermal conductivity is as high as 390 W/m·K (performance may vary slightly with different thicknesses), effectively improving the heat dissipation performance of the device.
Excellent ductility: easy to process and shape (wound or combined with other materials) to meet complex process requirements.
Anti-corrosion performance: The surface has undergone anti-oxidation treatment and is suitable for a variety of harsh environments.
Durability: Strong long-term stability, suitable for long-term electrical and electronic applications.

why choose us?

1/About product

The copper foil we produce has ultra-high purity, made from 99.95% electrolytic copper (with SGS material report), which reduces power loss caused by impurities.

Our products undergo precision processing using a full continuous rolling production line, with a thickness tolerance of ±0.005mm (compared to competitors' ±0.01mm).

Surface treatment of the copper foil: Mirror polishing (Ra ≤ 0.8μm), which is better than the industry standard of Ra 1.6μm.

2/About production strength
