Silver Cadmium Oxide (Ag/CdO)

Manufacturing process and delivery forms:

Ag/CdO materials are manufactured either by

blending of silver and cadmium oxide powder, compaction, sintering, and extrusion or
casting of silver cadmium grains, internal oxidation, and extrusion

Wires and profiles are produced by final drawing or rolling. Products are available with brazeable silver backing layer, and additional brazing alloy if required.

Key features:

excellent anti-welding properties on make, higher CdO content is improving anti-welding properties
low contact resistance compared to other metal oxides
contact resistance stable throughout the lifetime
low arc erosion, excellent arc extinguishing properties
tendency to material transfer in DC applications

Applications:

switches for domestic applications, main switches
earth leakage breakers, miniature circuit breakers
contactors
circuit breakers up to a switching current of 3000 A
general purpose relays
