FAQ
What is CCA-62%?
CCA-62% is the standard grade of Copper-Clad Aluminum with a minimum conductivity of 62% IACS. It consists of an aluminum core clad with a copper layer, manufactured using the Clad & Weld process with metallurgical bonding.
What applications are suitable for CCA-62%?
CCA-62% is suitable for building wiring (where permitted), coaxial cables, grounding conductors, and low-voltage applications. It offers the best cost-to-performance ratio among CCA grades.
How does CCA-62% compare to pure copper?
CCA-62% has approximately 62% of copper's conductivity, 59% lower weight, and 35-40% lower cost. For applications not requiring maximum conductivity, it provides an excellent alternative.
What is the derating factor for CCA-62%?
CCA-62% typically requires a derating factor of 0.80 for ampacity calculations, meaning it can carry approximately 80% of the current that a same-sized copper conductor can carry.
