Characteristics and Applications for AgCdO contact material

Contact Material in Huano:Type 3

AgCdO10,AgCdO20

AgCdO10,AgCdO20 Properties

CdO particles are finely distributed in Ag matrix. Under the action of arc, CdO decomposes and vaporizes, which cools down the contact surface,

so as to lower the arc energy and extinguish the arc. This material is of high welding resistance and electric wear resistance, low and stable contact resistance.

by increasing CdO content, the welding resistance of the material can be improved, but the contact resistance and temperature rise will also increase.

 

Main applications for AgCdO10,AgCdO20 contact material according to its properties:

 

Widely used to relays, contactors and AC/DC switches for medium or large current, circuit breakers for medium or small current; specially fit for AC contactors for medium or large current.

 

Delivery forms:

AgCdO alloy Wire,AgCdO alloy plate or AgCdO alloy rivet

 

Our company can offer various kinds of elecrical sheet or plates according to your drawings or samples.

 

 

Features for different contact sheet plate material

Pure silver sheet plate

 

(1) Pure silver has extremely high electrical conductivity

 

(2) Very low contact resistance rate

 

(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 appliances

 

 

 

AgNi sheet plate

 

(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

 

6) Wire of solid and composite rivets produced by powder sintering-extruding methods

 

 

 

AgSnO2 sheet plate

 

(1) AgSnO2 is the ideal material of 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 material which is empoldered and developed actively over the world

 

(5) For AgSnO2 contact material, the contact resistance can be controlled within

thelimited 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

 

 

 

AgZnO sheet plate

 

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

 

(2) The welding resistant and resistance against arc erosion of the contact is better

 

(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 breakerswith

large capacities

 

 

 

AgCdO sheet plate

 

(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 degrees centigrade, 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 low resistance rate

 

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

 

2:type: Round type/ rectangular type,head dimension: round tip:2mm-25mm

 

rectangular tip: W=3mm-20mm,L=3mm-25mm;tip thickness:0.5mm-3.0mm

4:Radius can be customers size

 

5: Products range: wall switch, relay, breaker, thermostat, mid/low voltage switch

 

6: Resistant to high-current, high current, Kang Da current corrosion and welding, hardness, strength is higher than normal contact

 

What are electrical contacts?

 

The contact is also called a tip, point, finger, wedge, button or segment.A single or multi-pole electrical product that contains movable and stationary contacts,

often including screws, springs and possibly other hardware is called a kit or set.

A contact opens and closes

(makes and breaks) to engage or interrupt an electrical circuit. They are usually used for switches,

relays, contactors and motor starters etc.

An electrical contact is defined as the interface between the current-carrying members of electrical/

electronic devices that assure the continuity of electric circuit, and the unit containing the

interface. The current-carrying members in contact, often made of solids, are called contact

members or contact parts. The contact members connected to the positive and negative circuit

clamps are called the anode and cathode, respectively.

Electrical contacts provide electrical connection and often perform other functions. The

primary purpose of an electrical connection is to allow the uninterrupted passage of electrical

current across the contact interface. It is clear that this can only be achieved if a good metalto-

metal contact is established. The processes occurring in the contact zone are complex and not

fully explained within the limits of present knowledge. Although the nature of these processes may

differ, they are all governed by the same fundamental phenomena, the most important being the

 

degradation of the contacting interface and the associated changes in contact resistance, load,

temperature, and other parameters of a multipoint contact.
