AgSnO2 (silver tin oxide) and AgCdO (silver cadmium oxide) material performance comparison

  AgSnO2 contact material is environmentally friendly and non-toxic, with excellent resistance to welding and arc ablation. Generally speaking, under the condition of large current, AgSnO2 has better arc ablation resistance than AgCdO; under lamp or capacitive load, the contact resistance of AgSnO2 is high, but under DC lamp or click load, it performs A low and stable contact resistance; compared to AgCdO under DC conditions, AgSnO2 material has better transfer performance. AgSnO2 contact material is widely used in various large-capacity contactors, power relays, medium and small-capacity low-voltage circuit breakers and automotive electrical appliances.
