2.Place of origin:wenzhou,China(mainland).

3.Cooperation: SANYO etc

4.Specification:All dimensions are fully according to customers requrements.

5. Over 15 Years Experience in producing Electrical Moving Contacts.

Electrical Contact Rivets Types:

Solid rivets, Bimetal Contacts/ Bimetallic Rivet,Trimetal rivets and special type contact rivets and contact buttons are also available.

Tri-metal Contact Overview:

Three composite(Tri-metal) rivet is processed by cold heading, used in solid rivet contact which is silver alloy and double-sided. This method can save 30%-70% of the material cost without affecting the functional performance.

Main material:

Ag/Cu, AgCdO/Cu, FAg/Cu, AgNi/Cu, AgSnO2/Cu, AgSnO2InO3/Cu, etc 

Characteristic of mocving contacts:

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 Inner

AgNi Contact:

Features:

(1) AgNi contact material contains 10% to 40% 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

(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

AgZnO Contact:

Features:

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

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

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

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

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

This kind of the electrical moving contacts have passed the certificate of SGS .

Application:

1) Electronics, communication, automotive industry, household appliances, Automobile

2) Switchgears, relays, mini-circuit breaker, switches, contactors, thermostats, etc

Packing:

Inner package: vacuum plastic package Outer package: carton package
