| Electrical contact materials | Applications | Solutions |
| AgSnO2/Cu Contact Rivet | Relays | AgSnO₂ offers strong resistance to arc erosion and material transfer. The composite rivet design combines an AgSnO₂ working layer with a copper base. By optimizing the material proportions and interfacial bonding process, the solution achieved a better balance of temperature-rise performance, electrical endurance, and bonding integrity. |
| AgSnO2 Contact Tips | DC Circuit Breakers | An atomized powder process was used to achieve tighter control of the material microstructure and a more uniform dispersion of SnO₂ particles within the silver matrix. This uniform microstructure supports consistent resistance to arc erosion and contact welding under high-current switching conditions. The BAg15CuP layer provides a reliable brazing interface between the contact tip and its copper carrier, helping the joint withstand the thermal and mechanical stresses generated during operation. By extending electrical service life and improving operating stability, the solution helped reduce lifecycle maintenance requirements and increase the equipment's safety margin. |
