Silver alloy electrical contacts

             Silver (Ag) in the material used for electrical contacts can be listed as the first. It has the highest metal conductivity, its value is 106%IACS. The disadvantage is that silver is easy to form a black sulfide (AgS) sulfide film, easy to wear and low hardness, but because of the physical properties of fine silver is widely used as a low energy circuit electrical contacts. Mainly used in radio communication with the micro-switch, controlled switches, thermostats, relays, calculators. Computers and other small current electrical field. The main products are silver contacts, Ag/Cu-silver/copper composite electrical contacts, silver/copper-nickel alloy-Ag/CuNi(8~10) composite electrical contact.
