Advantages and Applications of Standard Environmentally Friendly Triple Composite Silver Contacts

We know that there are many advantages for silver plated contacts, for example, it can enhance the current-carrying capacity of the terminal and it is cheap. So, the contacts parts with silver plating are often used in electric power or electricity. And silver alloy contacts produced with different materials and different functions are widely used for many industry fields as well. But for the standard environmental protection triple composite silver contacts, what advantages they have? And what are they used for? This article will share with you some knowledge about the advantages and applications of standard environmentally friendly triple composite silver contacts.

 

Basic knowledge about materials

 

Generally, the surface materials of standard environmentally friendly triple composite silver contacts are pure silver, fine-grained silver, silver nickel, silver copper, silver cadmium oxide, silver zinc oxide, silver tin oxide, silver tin indium oxide and so on. The substrates are copper, copper nickel etc. In order to improve the properties, these materials can be electroplated with gold, silver and nickel etc. on the surface to meet the requirements of application.

 

Application

 

AgCdo (silver cadmium oxide) series: they have a broad range of contact parts application, such as light switch, circuit breaker, electromagnetic switch, micro switch, motor protector, line starter, non-fuse circuit breaker control switch, heavy load relay and cam switch and so on.

 

AgSno (silver tin oxide) series: they are often used for automotive circuit breakers, micro switches, electromagnetic switches, various switches and high-energy bracelet points, household circuit breakers, etc.

 

AgNi (silver nickel) series: the range of their applications includes low-power switch, static bracelet point, line starter, circuit breaker micro switch, control switch, temperature regulator, and thermostat etc.

 

AgSnOlnO (silver tin oxide indium) series: they can be used for circuit breakers, electromagnetic switches, various switches and high-precision bracelets etc.

 

Pure silver and others: they can be used for automatic control switch, thermostat, baking machine, oven, timer, medium power switch and so on.

 

Advantages

 

Usually triple composite silver contacts include silver contacts, triple composite silver contacts, and composite silver contacts. They have long service life, environment protection, and good quality assurance that meet the requirements of national standards.

 

72-composite silver contacts


AgCdo (silver cadmium oxide) series: It has outstanding wear resistance, welding resistance and electrical and thermal conductivity, and the touch resistance is small and stable.

 

AgSno (silver tin oxide) series: it has high thermal stability, heat resistance, arc corrosion resistance and melting resistance, and silver tin oxide contact has long service life.

 

AgNi (Silver Nickel) series: When it is used for DC contacts components, it has good electrical and thermal conductivity, low touch resistance and stability, and electrical loss is small and uniform.

 

AgSnOlnO (silver tin indium oxide) series: It has better thermal stability and higher hardness, and has very good weld ability and burnout after use.

 

Pure silver: it has excellent conductivity, and it is often used for various metal contacts as electroplating layer. It is reasonable to choose silver plating for current-carrying which has high requirements. But it has some disadvantages, for example, it is easy to stick and solder.
