Frequently Asked Questions
What is Copper Clad Aluminum (CCA)?
Copper Clad Aluminum (CCA) is a composite conductor consisting of an aluminum core clad with a layer of pure copper. It combines the high conductivity of copper with the light weight and low cost of aluminum.
How does CCA compare to pure copper?
CCA offers 62-70% of the conductivity of pure copper with a lower density (3.26-3.63 g/cm³ vs 8.96 g/cm³). At equal dimensions, the conductor weight is lower. For equivalent electrical resistance, a larger cross-section may be required, so system-level weight reduction depends on conductivity, conductor size, insulation, termination and application design.
Is CCA a reliable alternative for power cables?
Yes, when properly sized to match the ampacity requirements, CCA is a reliable alternative. Our metallurgical bonding technology ensures the copper and aluminum are permanently bonded, preventing galvanic corrosion and ensuring long-term stability.
Not Recommended / Validation Boundaries
- Do not evaluate CCA or CCS as pure copper equivalents without design review.
- Outdoor cable projects should review corrosion and termination risks early.
- Material substitution without application validation and customer approval is not recommended.
- Specifications and acceptance criteria must be confirmed per product form and purchase order.
