Copperweld

The World Leader in Bimetallic Wire and Cable

Founded in 1915, Copperweld invented the copper-clad ground rod, and has long played its part in keeping electrical installations safe with bimetals.

Today, Copperweld manufactures copper-clad steel (CCS) conductors used in a variety of applications including automotive wiring harnesses, power transmission and distribution, power grid grounding, and signal transmission input wire for tracer wire products.

Copper-clad aluminum (CCA) is also manufactured and used for signal transmission in radio frequency telecommunication applications, such as CATV cables and cellular towers and antennas. In 2018, recognizing the impending world shortage of copper supplies, Copperweld brought copper-clad aluminum small circuit wire back to the U.S. residential home building market, with the East Park Manufacturing Campus focused on production of NM-B (Non-Metallic Sheathed Cable) and type MC (Metal Clad Cable) building wire.

Copperweld maintains three state-of-the-art research and testing laboratories to include a Building Wire Compliance Lab where Copperweld samples building wire product and tests the wire according to UL requirements, UL listings, and Intertek listings, a Metallurgical Materials Product Lab with unparalleled in the industry capabilities to ensure  there is a diffusion of molecules for a true bi-metallic bond, and a newly expanded Product Reliability & Performance Lab dedicated to electrical connection research.

Copperweld is an American-based company.
