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 tips or AgCdO alloy rivet
 
 
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.
 
 
Common questions about Huano contacts?
 
1. Can you help customers for designing electrical contacts?

2. Can you help us to choose suitable contact material?
We can recommend the most suitable contact material to customers according to the electrical contacts' application,base on a rich fund of knowledge of kinds of contact material
 
3. What kind of electrical contact material you can provide?
In Huono,we can provide Pure Ag ,AgSnO2 , AgSnO2ln2O3 , AgCdO , AgCuO10 , AgZnO , AgNi , AgCe , AgC , AgWC , AgW , CuW Etc contact material.
 
4. Can you provide free sampels for test?
As Huano Electrical Contacts Ltd. Has manufactured electrical contacts for many years,so they have many different types in stock,if the electrical contact you need is similar with the size in sotck,they can send you within one day,if you can not use the similar size,they can make samples and send them within 7days.
 
5. Can you make some special electrical contacts such as the special shape or using speical conact material?
 
We can provide some electrical contacts made by special materials, such as: CuW contact material,AgWC contact material,AgW contact material,AgCu contact material,AuAg, contact material ,AuAgCu contact material,AgCuNi contact material...
We also provide special shape electrical contacts according to customers' design.(want to see

6. How do you control quality?Can you give a simple description?
we provide trimetal Silver Electrical Contacts samples to customer for checking before production; we will not produce until the sample is approved; we will do the product inspection randomly in the process of production to detect the problem in time, we also will select random products to customers for checking according to customers requirements after the completion of the production before shipping.
For the products with high assembly requirements, we will ask customers to provide the assembly parts, to ensure that the products can be assembled ok before shipment.
 
7. Can you report during production?
During production,we mainly Provide valuable pictures or videos with our customers, we provide clear pictures of silver trimetal contact rivets samples to customers for checking before the shipment; provide pictures of products and cross section inpection report which is in the process of producing; provide the detail packaging pictures showing the quantity and packaging of each product clearly after the completion of producing.
 
8. How do you arrange freight?
For samples,as the weight is not big,we ususally use Express,such as UPS,FeDex,DHL,TNT,EMS,the gross weight below 100kg,we usually deliver them by air,for 100kg above,we usually deliver by ship,for some special case,if our customer is urgent to get the goods,we can arrange to send them by air.
Spcially,as we have had some forwarders who have cooperated with us for many years,they gave us big discount,so our freight fees are competitive,many customers who cooperated with us for many years gave feedback that the freight charges that we offered is much lower than the costs that the customers arrange the transportation by themselves, in general, the price can be cheaper by 30 percent to 50 percent, which help customers save shipping costs greatly.
