What Copperweld does
Copperweld Bimetallics, LLC is a privately held U.S. manufacturer of bimetallic wire and cable, founded in 1915 in Pittsburgh, Pennsylvania as the Copper-Clad Steel Company. Following the 2013 acquisition of CommScope's bimetallic assets, it became the only U.S.-owned and operated producer of bimetallic wire, with current manufacturing operations in Fayetteville, Tennessee and Telford, United Kingdom. The company uses proprietary molten-weld, continuous-casting, and vacuum-pressing processes to metallurgically bond copper to steel (CCS) or aluminum (CCA) cores, exploiting the skin effect to place copper where it carries current while using roughly one-sixth the copper of equivalent solid-copper conductors.
Copperweld sells four product families — Building Wire, Power Grid, Automotive, and Signal Wire — across residential construction, utilities and renewable energy, vehicle electrical systems, and specialty applications such as tracer and detonation wire. Flagship products include NM-B and Metal-Clad Cable for construction; Century, ArcAngel, Stingray, and Sunray for substation grounding, pole-top transformers, and photovoltaic interpanel wiring; and coaxial, primary, battery, and high-voltage cables for automotive. The company sells direct via a dedicated sales team and quote-based ordering, and its products carry UL, ASTM, NEC, IEEE, and CSA certifications, with the 2026 NEC now referencing 14 AWG CCA for 10-amp branch circuits.
Revenue is generated through hardware sales of bimetallic conductors, with pricing handled via direct sales quotes rather than public price lists. The go-to-market is B2B, targeting electrical contractors, utilities, automotive manufacturers, and specialty communications customers globally. Recent strategic activity — including the May 2026 integration of CCS grounding conductors into CDEGS and WinIGS substation design software and an active 2025-2026 product launch cadence — indicates the company is using standards wins and software ecosystem integration as primary growth levers.

Copperweld product offering
Product offeringCore offering
Copperweld manufactures and sells bimetallic wire and cable products made from Copper-Clad Steel (CCS) and Copper-Clad Aluminum (CCA) conductors, which metallurgically bond copper to a steel or aluminum core. The company sells its products across four business lines — Building Wire, Power Grid, Automotive, and Signal Wire — serving electrical contractors, utilities, vehicle manufacturers, and communications infrastructure operators.
Product overview
Copperweld is a bimetallic wire and cable manufacturer offering four product lines: Building Wire, Power Grid, Automotive, and Signal Wire. The Building Wire division includes NM-B Cable, Metal-Clad (MC) Cable variants (MC PCS, MC HCF, MC HCPCS, MC AGP), THHN/THWN-2, XHHW-2, UF-B, Thermostat Cable, Bell Wire, and Wire Connectors (twist-on and push-in splice connectors) for residential and commercial construction. The Power Grid division offers grounding conductors including Century, ArcAngel, Stingray, and Sunray for substations, utilities, and renewable energy applications. Automotive products include Coaxial Cable, Resistance Wire, Primary Wire, High-Voltage Cable, and Battery Cable. Signal Wire products include Tracer Wire, Coaxial Core, Detonation Wire, and Thermostat Wire for communications and mining applications. All products use Copper-Clad Steel (CCS) or Copper-Clad Aluminum (CCA) bimetallic construction combining copper's conductivity with the strength of steel or the lightness of aluminum.

One partnership is on record.
- CDEGS (Safe Engineering Services)coreCopperweld made its Copper-Clad Steel grounding conductors (Century and ArcAngel) available in CDEGS software, a widely used substation grounding design platform. This integration allows engineers to model CCS conductors directly in the software for the first time, removing a long-standing workaround that made it less likely for engineers to consider Copper-Clad Steel during design.

Most directly comparable peer in the U.S. building wire channel.
- Encore Wire (Prysmian): U.S. manufacturer of building wire (NM-B, MC, THHN/THWN-2, XHHW) and other cable products, now part of Prysmian Group. Competes head-to-head with Copperweld's Building Wire division in residential and commercial electrical distribution channels with overlapping product SKUs and certifications.
- Service Wire Company: U.S. manufacturer of building wire, utility cable, and industrial wire products including copper and aluminum conductors. Directly competes with Copperweld in building wire and utility/power distribution segments with similar channel positioning and product specifications.
Broad incumbents
- Prysmian Group: Global wire and cable leader with broad exposure across energy, telecom, and construction markets. Through the acquisition of Encore Wire and General Cable, Prysmian holds significant U.S. building wire share. Serves overlapping customer segments to Copperweld's power grid and building wire businesses with a much broader product portfolio.
