Silver-Cadmium Oxide
·Wire Materials
·Electrical Contacts
·AgCdO/Cu Composite Contacts
Characteristic:
Silver-Cadmium Oxide has good wear resistances, anti-welding, relatively constant contact resistance. Cadmium Oxide are dispersing all over the silver base, so the materials property increases in hardness and wear resistance. It is beneficial to cooling and are-suppression that the spread cadmium oxide particle can absorb large number of heat as decomposing under the arcing action. The resistance, increase in the electric life, and keep low contact resistance. Silver-Cadmium Oxide wires are made by advance oxidation method. Flap contacts added with the trace elements(T)are made by alloy internal.
