SILVER TIN OXIDE/SILVER TIN OXIDE INDIUM OXIDE

AgSnO₂ is the best material for substitution of AgCdO. It has very good welding resistance and arc erosion resistance, and has been widely applied to contactors, universal relays, magnetic latching relays and automobile relays.

AgSnO₂In₂O₃, with 3 - 5% of In₂O₃, can have better resistance against material transfer under DC load conditions, and is suitable for application in the field of automobile relays.
