Silver Tin Oxide Series (AgSnO2, AgSnO2In2O3)

The material of AgSnO2 has the properties of high life-cycles, good resistance against electric arc and contact sticking which is suitable for medium and high load current. But when it is used for low load current, the electric resistance might be unstable sometimes.

This issue could be improved by adding varieties of additives.  The material is also often used for electric contacts in application of vehicle relays due to its good resistance against contact erosion and property of anti-material transfer.

Silver tin oxide contact material has the advantages of high electrical life, arc resistance and adhesion resistance. It is suitable for medium and high load conditions, but when used in low load switches, it sometimes has the disadvantage of unstable contact impedance, but by adding A variety of trace elements, which can improve the wettability between silver-based and ceramic materials, and improve the silver-based viscosity of the joint melting, in order to improve the material properties and meet the needs of custom switching materials. Due to its resistance to arc erosion and excellent resistance to mass transfer, this series of contacts is also often used in applications such as vehicle relays.
