U.S. Copper Wire Market Size, Share & Trends Analysis Report By Voltage (Low, Medium, High), By Application (Building Wire, Power Distribution, Automotive, Communication, Renewable Energy), And Segment Forecasts, 2025 - 2030

U.S. Copper Wire Market Size & Trends

The U.S. copper wire market size was estimated at USD 9.14 billion in 2024 and is expected to grow at a CAGR of 6.1% from 2025 to 2030. This market is experiencing robust growth due to its essential role in electrical infrastructure, energy systems, automotive wiring, and telecommunications. Copper’s unmatched conductivity, thermal stability, and recyclability ensure its dominance in building wire and power distribution applications. Increasing investment in infrastructure modernization, rising construction activities, and the transition to renewable energy drive the need for high-performance copper wire across residential, commercial, and industrial projects. Advancements in energy-efficient technologies and electrification trends across transportation and utilities continue reinforcing copper wire’s relevance and long-term demand in the U.S. copper wire industry.

In the U.S. copper wire industry, the renewable energy sector remains a strong demand driver, particularly due to copper's essential role in transmitting electricity efficiently. In September 2024, Southwire announced a partnership with Statewide Renewable to install a solar system at one of its North Campus plants in Georgia, underscoring its commitment to renewable energy. The establishment is expected to produce around 5 megawatts of direct current electricity, supplying 15% to 20% of the site's energy needs, sufficient to power over 400 homes for a year. This highlights the growing demand for copper wiring in utility-scale renewable projects, as system operators prioritize materials with high conductivity and durability for reliable performance under extreme conditions. The initiative underscores America’s transition to clean energy.

In the automotive sector, copper wire continues to be indispensable for vehicle electrification and advanced communication systems. With the rapid advancement of Electric Vehicles (EVs), automakers are increasingly turning to high-voltage copper wiring to support battery systems, regenerative braking, and onboard diagnostics. General Motors has significantly bolstered its investment in EV charging infrastructure. In December 2024, GM teamed up with ChargePoint to install up to 500 ultra-fast DC charging ports under the "GM Energy" brand at dealerships and public locations across the U.S., featuring both CCS or NACS compatibility to improve charging access and efficiency for EV owners.
