Contact components

Types: Such as AG, AgNi, AgCdO, AgSnO2, AgZnO, solid, bimetal and trimetal rivets.
Carrier: Copper, bronze, brass, Beryllium bronze, etc, can be plated with silver or gold

Application: Relays, contactors, switches, controllers
Material: Brazed, riveted components of AgC, AgNi AgSnO2, AgCdO with Cu

Brazed or riveted components of AgNi, AgNi/Cu tips or rivets

AgNi materials have higher resistance to arc erosion and contact welding than AG, 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 wildly used in low voltage switching devices, such as powder relays, small contactors, light switches, temperature controllers, protective switch, etc.

Brazed or riveted components of AgCdO, AgCdO/Cu tips or rivets

CdO material gives the contact special properties, when the temperature is above 900 centigrade degree, CdO sublimes make contactor surface cool and arc extinguished automatically. This material combines a satisfactory resistance to arc erosion and welding.

The contacts used in almost every type of low voltage switching devices, such as micros witches, relays, light switches, contactors, switches for household appliances, some types of protective switches, as well as in certain type of circuit breakers.

Brazed or riveted components with AgSnO2, AgSnO2 /Cu tips or rivets

AgSnO2 and AgSnO2InO3 show high arc erosion resistance and a good resistance against contact welding. It is environment-protective materials, and it is considered to be the ideal substitute of AgCdO.

These contacts are wildly used in various kinds of contactors, relays, circuit breaks and switches, etc.

Contact components with AgC contact tips

AgC contact Materials show a very high resistance against contact welding and low contact resistance. Resistance against welding increases with increasing graphite content. AgC materials have self-lubricating behavior when used as sliding contacts.

AgC contact tips mainly used in protective switches such as MCB, MCCB, residual current protective switches, or motor protective switches. Normally, it implicated in asymmetric pairing with AgNi, AgW, AgWC or Cu.

Contact components with AgW contact tips

Contacts made of AgW show high anti-welding resistance and high resistance to arc erosion due to high melting point and high hardness of W, they also have good electrical thermal conductivity.

AgW contact tips are mainly used in low voltage MCCB and ACB and protective switches.

Contact components with AgWC, AgWCC contact tips

The AgWC contact materials, containing 40% to 65% of the refractory component WC, have high hardness and resistance to electric erosion, a low tendency towards contact welding, and a relatively stable contact resistance in service. Due to high AG content, AgWCC contacts have low contact resistance, and they have high anti-welding properties due to containing WC and graphite with high melting points. AgWC contacts are produced by powder metallurgy infiltration. AgWCC contacts are manufactured by sintering.

These contact components mainly used in heavy duty switching devices, such as MCCB, ACB, and residual current circuit breakers.
