Electrical Rivet

(4) It also has higher welding resistance and uniform arc erosion Inner

(3) Contact materials produced by powder sintering-extruding methods have higher density and low resistance rate

(2) When the temperature is higher than 900^oC, CdO is sublimated and the contact surface is cooled down in order to reduce and even extinguish the arc energy. This method can increase the resistance against welding

(1) AgCdO is a kind of most important contact material among silver metal-oxide materials, and it is widely used for low-voltage devices

Features:

AgCdO Contact:

(5) AgZnO contact material is mostly suitable for contactors and circuit breakers with large capacities

(4) AgZnO contact material is innocuous and has no pollution to the environment

(3) The AgZnO contact material has higher welding resistance and low arc erosion with strong magnetic arc blowing under large switching capacity

(2) The welding resistant and resistance against arc erosion of the contact making ZnO material a higher product

(1) ZnO, one type of material in AgznO contact, has comparatively higher thermal stability

Features:

AgZnO Contact:

(5) For AgSnO2 contact material, the contact resistance can be controlled within the limited range by putting in a small amount of additive of special metal-oxide
(6) 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 oxidation processing method

(3) AgSnO2 has higher resistance against welding and erosion than AgCdO material
(4) Non-poisonous. So it is a new material in contact

(1) AgSnO2 is the ideal material of AgCdO and has excellent properties of contacts
(2) AgSnO2 has higher thermal stability

Features:
