The silver plating layer is much cheaper than the gold plating layer, and has very high conductivity, light reflectivity and chemical stability to organic acids and alkalis, so the silver plating layer is much more widely used than the gold plating layer.

The silver coating is easy to polish and has good light reflecting, heat conducting, electric conducting and welding performances. Early silver coatings were used primarily for ornaments and tableware and have been used more and more in recent years on airplanes and electronics. In the electronic industry, communication configuration and instrument manufacturing industry, a silver coating is generally adopted to reduce the resistance of metal parts and improve the welding capacity of the metal parts; in addition, metallic reflectors in searchlights and other reflectors also need to be silvered. Silver atoms are easy to diffuse and slide along the appearance of the material, and are easy to breed in humid atmosphere to generate silver whiskers to cause short circuit, so that the silver-plated layer is not suitable for being used in a printed circuit board.
