powder metallurgy contacts AgWC alloy contact used for circuit breaker with high welding resistance
1. product name: powder metallurgy contacts AgWC alloy contact used for circuit breaker with high welding resistance
2. Main Materials: AgWC
3. General Description:
The AgWC contact materials containing the refractory component WC have high hardness and resistance to mechanical wear,a low tendency towards contact welding,and a relatively stable contact resistance in service.AgWC contacts are produced by powder metallurgy infiltration.
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 AgC.

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) AgNiC series
Widely used in omnipotence breakers such as DW45 intelligence coupling with AgW.
B) CuW series
Widely used in high voltage breaker.
C) AgWCAgWCC series
Mainly used in high electricity charge switchgear such as breaker, creepage switch. Generally they are used with AgNi ,AgWC together.
D) AgNi series
Widely used in DC/AC relay, designation switch, contactor, light switch, thermal controller, timer of washer etc.
E) AgW series
All kinds of omnipotence breakers, plastic breakers, heavy charge AC/DC contactorother switches.
F) 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.
G) AgC series
Mainly used in protective switch such as miniature breaker, creepage protective switch or motor protective switch with coupling contact in AgW.
