Copper Clad Aluminum (CCA) wire is a high-performance composite conductor featuring an aluminum core with a copper outer layer. This innovative design combines the excellent conductivity of copper with the lightweight and cost-effective properties of aluminum, making it ideal for numerous electrical applications.
Our CCA wire is manufactured in strict compliance with ASTM B566-78 standards, ensuring consistent quality and performance. The product is available in different classifications based on copper layer volume and mechanical state, including Class 10A, 15A, 20A (annealed) and Class 10H, 15H, 20H (hard drawn) variants.
The wire demonstrates excellent electrical characteristics with resistivity ranging from 0.0259-0.0274 Ω·mm²/m depending on the copper content. The conductivity at 20°C varies between 62.855% to 66.465% IACS across different grades, while maintaining a density between 3.32-3.94 g/cm³.
Key applications include:
- Electronic components and connectors
- High frequency signal transmission systems
- CATV coaxial cable conductors
- Radio frequency cables
- Power transmission and distribution networks
- Automotive wiring systems
- Building distribution cables
- Audio equipment components
The product offers significant advantages including lightweight construction, good electrical conductivity, and cost efficiency compared to pure copper alternatives. With diameter options ranging from 0.08mm to 8.25mm, our CCA wire meets diverse industrial requirements.
