Frequently Asked Questions
How does CCA-90% differ from pure copper?
CCA-90% achieves 92% of copper's conductivity with 35% weight reduction. For most applications, it performs functionally equivalent to copper while offering significant weight advantages.
What are the manufacturing challenges for CCA-90%?
The high copper volume ratio (40-45%) requires specialized manufacturing equipment and processes. The thicker copper cladding demands precise control during the Clad & Weld process to ensure uniform metallurgical bonding.
What niche applications use CCA-90%?
CCA-90% is used in aerospace wiring where weight is critical but copper-level performance is required, high-end audio equipment, specialty cables, and weight-sensitive systems requiring near-copper conductivity.
Is CCA-90% cost-effective?
CCA-90% costs approximately 80% of copper while providing 92% conductivity and 35% weight reduction. It's most cost-effective for applications where weight savings justify the premium over lower CCA grades.
