AG solid rivet
Pure AG has high electrical and thermal conductivity, low and stable contact resistance, and good workability. Because silver resistance to arc erosion and contact welding are limited, mechanical strength is low. Due to the small quantity of nickel in the fine grain silver, resistance to arc erosion and mechanical strength are higher than that of silver.
These contact are widely used in low current devices, such as relays, timers, auxiliary switches for household appliances, control switches
AgNi and AgNi/Cu Bimetal rivets
AgNi materials have higher resistance to arc erosion and contact welding than AG and FAG, AgNi materials show good workability and are easy to weld to contact supports, low tendency towards material transfer in DC applications. AgNi materials are environment-protective materials. This contacts widely used in low voltage switching devices, such as powder relays, small contactors, light switches, temperature controllers, protective switches etc.
AgCdo and AgCdo/Cu Bimetal rivets
Cdo materials gives the contact special properties, when the temperature is above 900 centigrade degree, Cdo sublimes make contact surface cool and arc extinguished automatically. This material combines a satisfactory resistance to arc erosion and welding. It is used in almost every type of low voltage switching devices, such as micro switches, relays, light switches, contactors, switches for household appliances, some type of protective switches, as well as in certain type of circuit breakers.
