AgZnO is a high resistance against contact welding characterizes materials, they also show a good resistance against arc erosion.contact resistance of AgZnO tends to be higher than that of AgCdO. AgCdO can be produced by means of pre-oxidation-sintering-extruding, mixing-compacting-sintering techniques as well as by internal oxidation. AgZnO materials are environment-protective materials.
AgSnO2/AgSnO2In2O3 are eco-friendly electrical contact materials. They have good performances in anti-erosion and anti-welding properties, and have good anti-material transfer properly in DC switching circuit. The main manufacturing processes are internal oxidation process, pre-oxidation process, chemical coating process, etc.
