2. Main Materials:
AgC
3. General Description
AgC contact materials shows 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.
4. application scope
Mainly used in protective switches such as MCBs,MCCBs, residual current protective switches, or motor protective switches. Application is normally in asymmetric match with AgNi, AgW, AgWC or Cu.

7. Relevant Series Applications
AgW, CuW, AgWC contacts choose different powder materials with adding inside Ni, Co mineral and by using pre-sinter and active sinter technology then improve their consistency and ameliorate electrical function of contact materials. Mainly used in middle and large capacity relay, contactor, middle and small capacity low voltage breaker, DC/AC switch, drive protective switch, creepage protective switch etc.
Their applications as follows:
A) AgW series
All kinds of omnipotence breakers, plastic breakers, heavy charge AC/DC contactorother switches.
B) AgWCAgWCC series
Mainly used in high electricity charge switchgear such as breaker, creepage switch. Generally they are used with AgNi ,AgWC together.
C) AgNiC series
Widely used in omnipotence breakers such as DW45 intelligence coupling with AgW.
D) AgNi series
Widely used in DC/AC relay, designation switch, contactor, light switch, thermal controller, timer of washer etc.
E) CuW series
Widely used in high voltage breaker.
F) AgC series
Mainly used in protective switch such as miniature breaker, creepage protective switch or motor protective switch with coupling contact in AgW.
G) Silver oxidized metal series
Mainly used in wasser mengen in relay,contactor, small and medium-sized capacity and DC low voltage circuit breaker switch powder protection switch and leakage protection switch,etc.
