Custom Electrical Contact Materials for Smart Home Electrical Contact Challenges in Smart Home Systems AgWC and AgSnO2 Contact Materials for Smart Home Circuit Protection
Smart home devices switch frequently across lighting, HVAC, and security applications. Without reliable contact materials, arc erosion, contact welding, and rising contact resistance can lead to abnormal temperature rise and premature device failure — particularly under the inrush currents generated by inductive household loads.
Fudar Alloy provides contact materials and assemblies for smart home electrical systems, including AgWC welded assemblies, AgSnO₂/Cu contact rivets, and profiled material tips for molded case circuit breakers, HVAC contactors, and thermostats. Designed for compact, high-frequency switching environments, these solutions deliver strong arc erosion resistance, weld resistance, and long service life. Custom specifications and application-specific development are available upon request.
| Electrical contact materials | Applications | Solutions |
| AgWC Welded Assemblies | Molded Case Circuit Breakers | Fudar provides complete AgWC welded assembly solutions supported by copper component processing, silver contact production, and automated welding capabilities. Through composition optimization, the silver content was significantly reduced while maintaining the required performance. |
| AgSnO₂/Cu Contact Rivets | HVAC Contactors | Fudar provides AgSnO₂/Cu contact rivets produced through an internal oxidation process. This solution improves weld resistance and arc erosion resistance. The product passed AC-3 testing and achieved an electrical life of more than 250,000 cycles without failure. It also supports the customer's localized manufacturing strategy and helps reduce logistics costs across the supply chain. |
| Profiled Material Tips | Thermostats | Fudar developed composite-structure profiled material tips that combine high electrical conductivity with strong weldability. These products help meet demanding temperature rise requirements, extend equipment service life, and improve overall cost efficiency. |
