Product Material


General Description

AgSnO 2 and AgSnO 2In 2O 3 show high arc erosion resistance and a good resistance against contact welding. By introducing certain additives,the AgSnO 2 materials,produced by the powder metallurgy technique(sintering and extrusion) 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 and AgSnO2In2O3 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.
