HIGH QUALITY TRI-METAL BUTTON-TYPE ELECTRICAL PUSH CONTACT (ROHS ISO) BIMETAL MANUFACTURE

Specifications

AgCdO/Cu Tri-metal Button Contacts 

Product Overview:

The small salient points can increase the material’s weldability, fasten the iron-based alloys like electrical contact, bimetal tip, stainless steel, etc.

Main Materials:

AgCdO/Cu, AgNi/Cu, AgSnO2/Cu, AgCe/Cu, etc.

Main Application:

It is suitable for impulse welding method and contact bridge welding. Widely used in electrical appliances such as temperature controllers, small capacity relays, etc.

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 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.

(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 Inside.

AgCdO Physical Property:

 Pure Silver Contact Feature:

(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

(6) 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
