Characteristics and Applications for AgSnO2 contact material

Contact Material in Huano:Type 4

AgSnO210,AgSnO212 Properties

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.

Delivery forms:

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.

5 Quality control:

we provide Electrical Rivet 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.

6. Provide valuable pictures anytime:

provide clear pictures of Electrical Rivet Contacts samples to customers for checking before the shipment; provide pictures of products 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.

7. Freight advantage:

many customers who cooperate with us for many years give 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.

8. Efficiency:

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.
