High Conductivity Copper Foil Tape C11000 is engineered for applications where electrical and thermal performance are critical. Made from electrolytic tough pitch copper (C11000), this tape is known for its exceptional conductivity and reliability in EMI shielding, electrical grounding, and high-performance electronic systems.
C11000 copper foil combines high purity with excellent mechanical properties, making it suitable for delicate electronics as well as industrial electrical applications. Its flexibility allows precise wrapping, shielding, and grounding while maintaining consistent conductivity. Protective coatings can enhance corrosion resistance, extending the service life in demanding environments.
As electronics and telecommunications systems become more complex, the demand for reliable EMI/RFI shielding and electrical connectivity grows. High-conductivity copper foil tape is essential in reducing electromagnetic interference, ensuring signal integrity, and protecting sensitive circuits.
The automotive, aerospace, and industrial machinery sectors also rely heavily on copper foil for grounding and shielding applications. Electric vehicles and renewable energy systems increasingly use copper tape in battery packs, inverter assemblies, and control electronics to maintain performance and safety.
Copper’s superior thermal conductivity is another advantage, making it ideal for heat dissipation in high-power electronics, transformers, and motors. With the growth of IoT devices and high-speed communication systems, high-quality copper foil tape is increasingly in demand for both small-scale and industrial applications.
