What is the difference between Material AgCdO and AgSnO2In2O3

 

AgCdO and AgSnO2In2O3 are both types of electrical contact materials used in switches, relays, and other electronic devices. However, they have different compositions and properties.

AgCdO is a silver-based contact material that contains a small amount of cadmium oxide. It is commonly used in low-voltage electrical switches and relays because of its high resistance to welding and low contact resistance. However, cadmium is a toxic material, and its use is restricted in many countries due to environmental and health concerns.

On the other hand, AgSnO2In2O3 is a silver-based contact material that contains tin oxide and indium oxide. It is a more environmentally friendly alternative to AgCdO because it does not contain cadmium. AgSnO2In2O3 has a low contact resistance, good arc erosion resistance, and high thermal stability, making it suitable for high-current applications such as power switches.
