Silver cadmium electrical contact(AgCdO) has high fusion welding resistance, electric wear resistance and low contact resistance.In some specific fields, so far, no other material can be replaced. Increase Cadmium oxide content can improve the material fusion welding resistance, but will increase the contact resistance and the temperature rise, meanwhile reduce the material of plasticity.
Silver Cadmium Electrical Contact
Electrical Contact factory, more than 10 years manufacture experience, attained ISO9001, work on OEM and ODM projects.
1. Introduction of Silver Cadmium Electrical Contact
Silver cadmium oxide( AgCdO )electrical contacthas high fusion welding resistance, electric wear resistance and low contact resistance.In some specific fields, so far, no other material can be replaced
Increase Cadmium oxide content can improve the material fusion welding resistance, but will increase the contact resistance and the temperature rise, meanwhile reduce the material of plasticity.
2. Application of Silver Cadmium Electrical Contact
AgCdO contacts Mainly usedinlow-middle voltage household electrical appliances switches, relay miniature circuit breaker, AC contactor etc.
3. Main Materials for Silver Cadmium Electrical Contact
Main face material: AgCdO10, AgCdO12, AgCdO15, AgCdO20
Main base material : Cu, CuNi
