Product Description

AgCdO Contact: Features: (1) AgCdO is a kind of most important contact material among silver metal-oxide materials, and it is widely used for low-voltage devices (2) When the temperature is higher than **0oC, 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 (3) Contact materials produced by powder sintering-extruding methods have higher density and lower resistance rate (4) It also has higher welding resistance and uniform arc erosion Inner AgNi Contact: Features: (1) AgNi contact material contains *0% to *0% Ni (2) Produced by powder metallurgical production, with low and stable contact resistance, high hardness and mechanical strength (3) Material transfer in case of DC is very low (4) High electrical and thermal conductivity (5) With very low arc erosion. On making higher current, normally asymmetric pairs with Ag contact materials are applied (6) Wire of solid and composite rivets produced by powder sintering-extruding methods Pure Silver Contact: Features: (1) Pure silver has extremely high electrical conductivity (2) Very low contact resistance (3) Easy to solder (4) It is easy to produce, so silver is an ideal contact material (5) It is one of the most widely used materials in small capacity and voltage AgSnO2 Contact: Features: (1) AgSnO2 is the ideal material of replacing AgCdO and has excellent properties of contacts (2) AgSnO2 has higher thermal stability (3) AgSnO2 has higher resistance against welding and erosion than AgCdO material (4) Non-poisonous. So it is a new and environment-friendly material used in 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
