Product Material
AgSnO2
General Description
AgSnO2 show high arc erosion resistance and a good resistance against contact welding. By introducing certain additives,the AgSnO2 materials,produced by the powder metallurgy technique can be modified in such a manner that contact resistance and over temperature behavior can be maintained low and stable over service life. Material transfer in DC operation is low. Contact materials of the AgSnO2 type are non-toxic and friendly to the environment.
Application Scope
Widely used in various kinds of contactors、relays、circuit breakers and switches、and so on。
