OEM factory offer Silver Tin Oxide electrical contacts
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.
Silver Tin Oxide / Silver Tin Oxide Indium Oxide has excellent burnout resistance and fusion welding resistance. By adding some additives and using powder metallurgy skills (sintering and kneading) and internal oxidation method skills to manufacture AgSnO2 data, the use of persistent contact resistance and low temperature rise is stable. There is little data handling when in direct current, and it is non-toxic environment.
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
