2. Main Materials: AgWCC
3. General Description:
Due to high Ag content, AgWCC contacts have low contact resistance. They have very high anti-welding properties due to containing tungsten carbide and graphite with high anti-welding properties due to containing tungsten carbide and graphite with high melting point.AgWCC contacts are manufactured by sintering.
4. Application Scope
Mainly used in heavy-duty switching devices, such as circuit breakers,residual current circuit breakers.In many cases they are used in asymmetric match with AgNi,AgW or AgWC.

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) CuW series
Widely used in high voltage breaker.
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) AgWCAgWCC series
Mainly used in high electricity charge switchgear such as breaker, creepage switch. Generally they are used with AgNi ,AgWC together.
F) AgC series
