3.Material:AgcdO

Product features  

AgCdO is the alloy material in the silver matrix which distributes cadmium oxide (CdO) in a specific form (such as fibrous, granular, etc.) with specific morphology and particle size.  AgCdO materials have the following advantages:  
 

1).Self-extinguishing arc ability and low and stable contact resistance.  The material enhanced phase CdO is easy to decompose at high temperature, decomposition temperature 900°C, decomposition heat absorption, reduce arc energy, so that the contact surface cooling, at the same time, Cd sublimation into gas, blowing arc and surface self-cleaning effect, produce stable contact resistance.  

2). Excellent arc erosion resistance and welding resistance.  The enhanced CdO “anchored” the silver that melted under the arc, preventing it from blowing apart.  
3). High electrical and thermal conductivity.  
Contact performance and application range  
These materials can be prepared by powder metallurgy or internal oxidation. 
Material:Nickel silver(AgNi)
Product features  
High electrical conductivity and arc resistance.  
Contact performance  
Products are widely used in industrial and household short circuit and leakage protection devices.
