 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.

Silver tin oxide/silver tin oxide indium oxide
Silver tin oxide is the most ideal environmentally friendly low-voltage contact material for replacing toxic silver cadmium oxide. It has excellent resistance to fusion welding and arc erosion resistance.
Gradual replacement of silver cadmium oxide materials is widely used in contactors and general-purpose relays, magnetic holding relays, and automotive relays. Added 3~5wt.%
Indium oxide silver tin oxide indium oxide material has better resistance to material transfer under DC load conditions and is suitable for use in automotive relays and other fields.
In order to meet the diversity and individual needs of low-voltage electrical appliances, the company has developed a variety of silver tin oxide materials for use, with a tin oxide content of 8 to 16 wt.%.
The content of indium oxide is 0~5wt.%. The mechanical and physical properties and application of the main grade materials are shown in the following table.
