The enameled copper wire is our common enameled wire material. There is a question about its color. Enameled copper is extremely soft (also called weak) copper with a colored layer and plastic coating to seal it.

Silver-plated enamel copper is plated with silver on the soft copper before the color and plastic. Compared with ordinary enamel copper, it can produce brighter and lighter colors.

Enameled copper wire used to have consistent color and quality-no longer. This is due to changes made by the wire manufacturer-everyone who bought this wire since 2010 has felt these problems-not just ourselves.

The color may vary from batch to batch and from specification to specification. The quality of the plastic coating may also vary, and it may condense. Due to copper corrosion, the end of the ring may be green. These facts are now considered normal for the Round Enameled Copper Wire which means that we do not consider them to be defects in the return.
