Silver cadmium oxide
Silver cadmium oxide has good resistance to fusion welding and arc erosion due to the violent decomposition and evaporation of cadmium oxide under the action of arc.
Low and stable contact resistance. At the same time, silver cadmium oxide also has good processing properties.
Cadmium oxide has certain toxicity, and the increase of its content can improve the anti-welding performance of silver cadmium oxide materials, but it will increase the contact resistance and temperature rise.
At the same time reduce the processing properties of the material.
