Characteristics and Applications for AgSnO2 contact material
Contact Material in Huano:Type 4
AgSnO210,AgSnO212
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.
