Characteristics and Applications for AgSnO2 contact material
Contact Material in Huano:Type 4
AgSnO2 is a nontoxic material, compared to AgCdO, and has very good and stable welding resistance and arc erosion resistance.
It has better erosion resistance than AgCdO in the current range of 500 ~ 3000 A, and shows better welding resistance than AgCdO and AgNi under lamp load and capacitive load.
While under AC resistive load, the contact resistance of AgSnO2 is a little higher than that of AgCdO, but it shows low and stable resistance at DC lamp / motor loads (such as automobile relays).
Under DC condition, AgSnO2 has less material transfer compared to AgCdO.
Main applications for AgSnO210,AgSnO212 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.
AgCdO alloy Wire,AgSnO2 alloy tips or AgSnO2 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?
We can help customers design the best electrical contacts by using different processing procedures to achieve good function and save costs according to the application,according to many years' experience for electrical contacts manufacturing.
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
Special electrical contacts,please visit Huano website's product category-special electrical contacts
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.
9. How about communication in Huano?
Our sales department communicates with customers by using a variety of online tools (Skype, MSN, Trademanager,Wechat,WhatsAPP ...), telephone, and e-mail, and adjusts the working hours according to customer time difference to keep in touch with customers and answer customer inquiries at any time, customers can use PAYPAL, western union and other online payment platform to pay a small amount of sample fee to shorten the sample production time.
