Description:AgCdO rivet: AgCdO is kind of most important contact material among silver metal-oxide materials and it is widely used in low-voltage devices, when the temperature is higher than 900oC, CdO is sublimated and the contact surface is cooled down and the arc energy is reduced and the arc is extinguished. It can also increase the resistance against welding. Contact materials produced by powder sintering-extruding methods have higher density and low resistance rate. Higher welding resistance and uniform arc erosion than internally oxidized material with same composition. AgNi rivets: AgNi contact material containing 10% to 40% Ni. It produced by powder metallurgical production have low and stable contact resistance, high hardness and mechanical strength. The material transfer in case of DC is very small. So it is high electrical and thermal conductivity. The contacts have very low arc erosion. On making higher current normally asymmetric pairs with AgC contact materials is applied. Wire of solid and composite rivets produced by powder sintering-extruding methods. AgSnO2 is the ideal material of AgCdO instead of material and has excellent properties of contacts. As the thermal stability of SnO2 is higher.AgSnO2 has higher. AgSnO2 has higher resistively against welding and low are erosion than AgCdO material, and is poisonous-less. For AgSnO2 contact material, the contact resistance can be controlled within the limited range by putting in a small of amount of additive of special metal-oxide. It is a activity developed and recommended new contact material in the world. In this aspect contact materials produced by powder metallurgy processing method have higher resistance against arc erosion and less arc bumming than those produced by intimae oxidation processing method. AgZnO rivet: The higher thermal stability of ZnO in AgznO contact material, the welding resistively and resistively against arc erosion is also higher. AgZnO contact material is poisonous-less will not pollute the environment will cause higher contact resistance this problem can be solved by increasing the contact strength by powder metallurgy processing method have higher welding resistively and low arc erosion with strong magnetic arc blowing under large switching capacity than those produced by internal oxidation processing method. AgZnO contact material is most suitable to be used in contactors and circuit breakers with large capacities. Pure silver: Pure silver has extreme high electrical conductivity and thermos conductivity and very low contact resistance. It is easy to produce, so silver is and ideal contact material. But silver is the very low resistively against welding. So they mainly used in small capacity low-voltage electric apparatus. The disadvantage of silver is the silver particles will be transferred under DC current, and silver is the very low receptivity against sculpture corrosion. Silver contact material is mainly used in communication technology, and control technology, such as relays, micro switches and auxiliary switches.
