AgCdO is one of the most widely used group of alloys in the field of low voltage electric apparatus. They show a satisfactory resistance against contact welding with good arc erosion and quite low contact resistance over its complete service life. Atomizing-sintering-extrusion, and melting and subsequent internal oxidation are the two techniques to produce AgCdO.

AgCdO is the alloy that is used in almost every type of low voltage switching devices. For example: Relays, light switches, household appliances, contactors, some types of circuits, and any switchgear that requires the breaking capacity between 10 & 1000A and 24 & 600V in AC or DC.
