Silver nickel(AgNi)



Overview: Silver nickel is more resistant to fusion and burnout than pure silver or fine grain silver. These two properties of the product are improved due to the increased nickel content of the high melting point. All silver-nickel materials are very workable and easy to solder. When the DC is turned on and off, the material transfer is small, and silver nickel is an environmentally friendly material.

Applications: Silver nickel products are widely used in low voltage switchgear. Such as relays, small current contactors, light switches, temperature controllers, protection switches (with asymmetric matching contacts with AgC, AgZnO, AgSnO2, etc.).

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.
