AgNi materials have good conductivity and resistance to contact welding, can be used under lowcontact pressure. Compared with the silver-copper alloy, AgNi materials have a lower and more stable contact resistance. The property of resistance to arc erosion is improved with increasing Ni content, but also increasing in contact resistance.
AgNi contact are mainly used in low- and middle-load switches, micro-relays, as well as the small load of contacts, AC circuit breakers.
