CCA is a bimetallic product made by an industrial process called cladding. A bimetal is a metal that has two distinct metallic regions that are metallurgically bonded stronger than the two materials that are bonded. The core is made of AA 8000 series aluminum with an outer layer of high-purity copper.

The low oxygen content minimizes conductor oxidation, which means the termination does not require an oxidation-resistant splice compound. The cladding process produces a unique metal that is stronger than the two metals it combines and forms a conductor that is flexible, resilient, thermally stable, and strong.

When installing communication cables, CCA allows cables to take advantage of all the advantages copper offers, while maintaining a more affordable price tag and helping protect the world's limited supply of copper. CCA is made by bonding a layer of pure copper to an aluminum core. While the CCA we drew obviously contains less copper than pure copper cable, it provides almost the same conductivity, just slightly higher resistance.
