Copperweld®
Building Wire

Engineered for better performance
and efficiency

Upgrade your building wire

Copperweld® Building Wire is a Copper-Clad Aluminum (CCA) bimetallic conductor that, when installed to NEC requirements, offers greater current-carrying capacity than its alternatives.  Due to its specific rating in Code, Copperweld is arguably the most energy-efficient conductor in the market.  This offers cost-saving benefits to owners of homes and buildings, while also conserving energy for the good of society. CCA de-incentivizes theft because of its nearly inseparable metallurgical bond and aluminum content.  CCA is fully recyclable and is recycled every day.  However, traditional scrap dealers cannot treat CCA as if it were single-metal copper.  This greatly decreases the value of CCA to traditional scrap dealers, causing them to likely deny its purchase. Without a buyer, thieves lose interest.

Copper where it counts

Copper is a valuable resource. Copperweld building wire is engineered to put copper where it counts: at the points of termination and splices. In using less copper to deliver superior performance, Copperweld frees up valuable copper to be used in more society-critical applications than commodity wire and cable.  As a beneficial consequence of its bimetallic properties, Copperweld features built-in theft deterrence. Although fully recyclable, CCA scrap holds a small fraction of the value of single-metal copper scrap, making it much less desirable to copper thieves.

Theft Deterrent

Metallugically bonded conductor results in lower scrap value, reducing theft.

Energy Efficient

Better energy efficiency than standard residential branch circuit wiring.

Cost Stable

Reduced exposure to commodity fluctuation improves your bottom line.

Wired to Protect™

50 years of trusted performance

Copperweld building wire is made with genuine Copperweld Cu-Clad Aluminum wire. Cu-Clad Aluminum (CCA) has been trusted for over half a century as a safe alternative to copper. Cu-Clad Aluminum building wire has been code compliant and product safety listed since 1972. Due to its favorable ampacity rating in the NEC, Copperweld runs more efficiently in the circuit than its alternatives, allowing for lower heat at electrical connection points, and pointing to better performance of household appliances and circuit components.

Code Compliant

NEC Compliant for 600 Volt residential branch circuit conductors since 1972.

Safety Tested

Listed by UL and ETL for various NEC wiring methods.

Performance Proven

50 years of safe residential use with standard circuit components.
