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.

Market Concentration & Characteristics

The industry growth stage is medium, and the pace of market growth is steady. The U.S. copper wire market continues to grow steadily, driven by its indispensable role across core infrastructure, including residential and commercial construction, power transmission, automotive systems, and communication networks. Copper wire remains preferred due to its superior electrical conductivity, thermal performance, and long-term reliability. The demand for durable, high-efficiency wiring systems is expected to accelerate as the country shifts toward electrification and renewable energy integration. Industry players are responding by ramping production capabilities, enhancing process efficiencies, and investing in sustainable technologies to meet regulatory and commercial expectations.

Innovation remains a defining feature of the U.S. copper wire industry, with manufacturers focusing on modernizing production facilities, integrating digital monitoring technologies, and reducing environmental impact. Companies are implementing advanced rod mill systems, energy-efficient manufacturing lines, and traceability solutions to improve product quality and operational performance. Merger and acquisition activity has played a pivotal role in shaping the U.S. market, with several strategic consolidations aimed at expanding market presence and improving operational synergies. In April 2024, Prysmian Group announced the acquisition of Encore Wire and completed this acquisition in July 2024. The deal, valued at approximately €3.9 billion (USD XX billion), will enhance Prysmian's North American footprint and broaden its product offering in building and power wire segments.

Voltage Insights

The low segment registered the largest revenue share of 51.9% in 2024. This is attributable to its significant utilization in residential, commercial, and light industrial applications like building wiring, LAN cabling, and appliance power supply. A recent development reinforcing this dominance is ABB’s announcement of a USD 120 million investment in March 2025 to expand its low-voltage electrification production in Selmer, Tennessee, and Senatobia, Mississippi. This initiative will boost manufacturing capacity by over 50% and support increased demand from data centers, utilities, and building projects.

The high segment is expected to grow at the fastest CAGR of 6.4% over the forecast period. This growth can be attributed to rising investments in utility-scale infrastructure and grid modernization and the growing transmission requirements of renewable energy systems. These applications rely on copper's high conductivity and thermal stability to ensure electricity's safe and efficient delivery across long distances and demanding environments. As government initiatives and private sector projects increasingly prioritize grid resilience and electrification, the role of high-voltage copper wire in power infrastructure is expected to expand significantly, reinforcing its strategic importance in the evolving energy landscape.

Application Insights

The building wire segment accounted for the highest revenue share of the U.S. copper wire market in 2024. This segment serves as the backbone for residential and commercial construction, power distribution, lighting systems, and appliance connectivity sectors. In June 2023, Southwire Company announced a 30% expansion of its Florence, Alabama, manufacturing campus, adding approximately 340,000 square feet. This development directly supports the company's goal of increasing commercial and residential copper building wire output capacity, which remains among the highest demand applications in the U.S. copper wire industry. The expanded facility will enable Southwire to meet growing construction and infrastructure needs across housing, commercial spaces, and institutional buildings. With construction scheduled for completion in 2025, this move reflects the company's long-term commitment to scaling production with rising demand for efficient, high-quality copper wiring solutions in the building sector.

The renewable energy segment is expected to grow at the fastest rate over the forecast years. This growth can be attributed to the scaling up of solar farms, wind turbines, and associated grid interconnection infrastructure. Copper's exceptional conductivity, resilience to thermal stress, and recyclability make it ideal for these renewable installations, particularly in long-length cables and grounding systems. Alongside renewable energy, automotive applications also rely heavily on copper wiring. Modern EVs integrate copper in safety sensors, infotainment systems, charging ports, and battery management circuits, underscoring the metal's versatility across various sectors.
