Why This Matters
As global demand for copper intensifies—driven by the surge in electric vehicles, renewable energy, and national electrification goals—preserving copper resources is critical. The U.S. Department of Energy has classified copper as a Critical Material due to supply chain vulnerabilities. Construction, particularly building wire, currently consumes 20% of the U.S. copper supply.
Copperweld’s Copper-Clad Aluminum (CCA) NM-B Building Wire offers a sustainable solution by reducing copper usage to 1/6 of that of solid copper wire, while maintaining reliable performance. The company’s output—expected to exceed 250,000 miles by end of 2025—has already saved nearly 59 million pounds of copper, freeing this vital resource for high-growth sectors like EVs and solar power.
Widespread adoption of CCA building wire could save hundreds of millions of pounds of copper nationwide, ensuring the U.S. can meet its climate goals and economic development objectives without exacerbating material shortages. It represents a simple, scalable shift that strengthens both environmental sustainability and industrial resilience.
