SC is an abbreviation for silver-covered copper, also written SCC, a copper conductor coated with silver to improve high-frequency conductivity and oxidation resistance.
SC stands for silver-covered copper, a conductor in which a copper core is coated with a layer of silver. Silver is the most conductive metal, and because high-frequency current tends to flow near the surface of a conductor, a silver coating improves conductivity at high frequencies. The silver also resists oxidation better than bare copper, which helps preserve performance and solderability over time. SC is also written SCC.
Silver-covered copper conductors are valued in high-frequency and high-temperature applications, including certain coaxial and signal cable and demanding electronic wiring. The silver coating addresses the skin effect that makes surface conductivity important at high frequencies.
In commercial and industrial wire, silver-covered conductors serve where high-frequency performance or oxidation resistance is needed. Recognizing the SC designation is part of identifying a conductor built for these demands.
Because high-frequency current flows near a conductor's surface, the silver coating on silver-covered copper addresses the skin effect directly, supporting low-loss signal transmission, which is why SC and its equivalents appear in coaxial, signal, and demanding electronic wiring.
Recognizing the SC designation is part of identifying a conductor built for high-frequency performance or oxidation resistance in coaxial, signal, and electronic wiring.
