Installation and Performance

Copper where it counts

Copperweld® Building Wire is made with CCA, a standardized copper bimetallic conductor where oxygen-free copper occupies its periphery and surface.

As a result of its copper cladding, Copperweld building wire connects like copper.  Twenty-seven percent of the wire's mass is copper.  The core of CCA is composed of 8000 Series building-wire-grade aluminum.  Through the process of metallurgical bonding, Copperweld conductors are considered by the NEC to be galvanically similar to copper and dissimilar to aluminum.
