Silver zinc oxide(AgZnO)
Overview: Silver zinc oxide has better resistance to soldering and burnout, and its contact resistance is higher than that of silver cadmium oxide. Silver zinc oxide can be produced by a pre-oxidation-sintering-extrusion, a mixing-molding-sintering process, and an internal oxidation process. Silver zinc oxide is an environmentally friendly material.
Applications: Mainly used for circuit breakers, especially universal circuit breakers. And for motor protection switches, leakage circuit breakers, AC relays.

AgSnO2
Overview: Silver tin oxide is an environmentally friendly electrical contact material with good resistance to burning and fusion welding. It has strong resistance to material transfer in DC switching circuits and is widely used. Mainly include: alloy internal oxidation method, pre-oxidation method, powder metallurgy method, chemical coating method and other manufacturing processes.
Applications: Widely used in all types of contactors, relays, circuit breakers and switches.
