Silver-plated copper wire Silver-plated copper wire is called silver-plated copper wire or silver-plated wire in some occasions. It is a thin wire drawn by a wire drawing machine after silver-plating on oxygen-free copper wire or low-oxygen copper wire. . Silver-plated copper wires are divided into silver-plated soft round copper wires and silver-plated hard round copper wires. The silver-plated soft round copper wire is annealed to change its physical properties to achieve the purpose of softening. A good silver-plated copper wire coating is continuously and firmly attached to the surface of the conductor, and the surface of the sample does not become black after the sample. The surface of the silver-plated coating should be smooth and continuous, free of harmful defects such as silver particles, burrs, and mechanical damage.
