Copper-Coated Steel Wire

A steel wire that has been copper coated by mechanical, chemical or electrochemical processes to enhance corrosion resistance, improve electrical conductivity, provide a base for other less adherent electroplated metals, or to provide a lubricant for subsequent drawing. Copper is usually chemically deposited by a simple displacement process based on copper sulfate with various additives such as chloride, in­hibitors and wetting agents. Subsequent drawing is essential to attach the copper firmly to the base metal by the compression effect of drawing.
