Copperweld® is the original copper-clad steel (CCS) wire, a groundbreaking product first pioneered by engineers in 1915. Copperweld® CCS is a composite in which highly conductive, corrosion-resistant copper cladding is metallurgically bonded to a strong, durable steel core through a continuous, solid cladding process using pressure rolling for primary bonding.
The thin copper cladding remains at constant thickness surrounding the steel and comprises a small minority of the overall wire diameter, but yields a conductivity substantially greater than that of unclad steel. CCS wire is an extraordinary conductor that provides benefits that neither metal can provide alone. Because the bulk of the current travels along the wire's skin, it is ideally suited for high-frequency applications.
Brilliant for use with wire antennas due to its strength ...... Used by the US military so it must be good !
