2. Main application
Inner Oxidized Electrical Contact are widely used in low voltage electrical appliance
(1), AgSnO2,AgSnO2In03series: Widely used in AC Contactor (CJ20,CJ40,3TF ,ETC)Power AC Switch (>=50KW),DC Contactor ,AC DC Power Relay ,Automobile and low voltage circuit breaker.
(2), AgSnO2 series: Widely used in low voltage circuit breaker with rating ,electricity within 200A(such as DZ15 series ,especially omnipotence breaker )drive socket, protective socket, AC Relay DZ5L series breaker etc. Some large capacity switches also use AgZnO materials such as ME omnipotence breaker.

3. Product introduce
Oxidized contact characteristics are as follows:

Inner Oxidized Electrical Contact owns excellent consistency ,tiny Oxidized material particle ,arc corrosion resistance and long electricity life .
Adding nickel and thulium to AgSnO2,AgSn02In2O3,AgZn02,AgCu0,AgCd0,etc with the technology of low temperature high pressure oxidized takes effect on making grain tiny ,dispersion and aggrandizement ,consequently improves their mechanical strength ,ameliorate fusion ,arc corrosion resistance and abrasion.
Adopting melting pulverization and pre-oxidized manufacturing methods can make high quality contact material with the advantage of grain thin and organization uniformity ,no defection in microcosmic structure ,eliminating oxide leanness area.
