AgSnO2 electrical contacts for switches
Electrical contacts factory, more than 12 years manufacture experience, attained ISO9001-2015, work on OEM and ODM projects..
1. Introduction of Silver tin oxide electrical contact
Silver tin oxide ( AgSnO2 ) electrical contact are environmental protection and non-toxic, with excellent anti fusion welding and arc ablation resistance performance.
In general speaking, under the condition of larger current, AgSnO2 has better ability of arc ablation resistance than AgCdO, and under the lamp or capacitive load, AgSnO2 showed a stronger ability to resist current shock than AgCdO, AgNi.
2. Application of Silver tin oxide electrical contact
AgSnO2 electrical contacts are widely used in large capacity contactor, power relay, medium and small capacity of low voltage circuit breaker, and automobile electronics etc.
3. Main Materials for Silver tin oxide electrical contact
Main face materials: AgSnO2 8, AgSnO2 10, AgSnO2 12, AgSnO2 15, AgSnO2 20
Main base materials : Cu, CuNi
