Powder Metallurgy contacts AgWC alloy contact used for circuit breaker with high welding resistance:
1. Product: powder metallurgy contacts AgWC alloy contact used for circuit breaker with high welding resistance
2. Main Materials: AgWC ect.
3. 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:
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.
