Product Description

Silver nickel
Silver nickel has the advantages of good arc transfer characteristics, low contact resistance and stability, and excellent processing performance, and has medium and small currents.
Good anti-welding performance and arc erosion resistance, strong resistance to material transfer under DC conditions; increased nickel content can be mentioned
High material resistance to soldering, but slightly increases contact resistance and temperature rise.
The special method of adding a small amount of additives can significantly improve the anti-welding and arc erosion resistance of silver-nickel materials.

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.
