Custom Electrical Contact Materials for Smart Buildings Electrical Contact Challenges in Smart Building Systems AgSnO2 AgC Contact Materials for AC Contactors, MCBs and Relays
Smart building electrical devices switch frequently throughout the day. Without reliable contact materials, arc erosion, contact welding, and rising contact resistance can lead to abnormal temperature rise and premature device failure across HVAC, lighting control, and security systems.
Fudar Alloy provides advanced contact materials and assemblies for smart building electrical systems, including AgSnO₂ contact assemblies, AgC contact tips, rivet contacts, and silver-reduction solutions for AC contactors, MCBs, power relays, and air circuit breakers. Designed for high-frequency switching applications, these solutions deliver stable electrical performance and long service life. Custom specifications and application-specific development are available upon request.
| Electrical contact materials | Applications | Solutions |
| AgSnO₂ Contact assemblies | AC Contactors | Fudar Alloy's AgSnO₂ contact assemblies combine good conductivity with strong anti-welding performance. They help resist sticking under high-current impact and provide strong arc erosion resistance, supporting reliable operation in HVAC, ventilation, and water system applications. |
| AgC Powder metallurgy contact tips | Miniature Circuit Breakers (MCBs) | ① Achieve high material density: Material density can reach up to 99.9%, with electrical life exceeding 6,000 operations. ② Low and stable contact resistance: To reduce premature failure, control temperature rise, and reduce power loss, supporting both safety and energy efficiency. |
| Rivet contacts | Power Relays | Fudar Alloy provides high-consistency rivet contacts through refined process control across material preparation, forming, welding, inspection, and batch management. These contacts help reduce false signals and switching errors in intelligent control systems. |
| Silver-saving contact (Solutions) | Air Circuit Breakers | Fudar Alloy has developed silver-layer optimization solutions. By coordinating AgNi material design with welding process optimization, we help customers reduce silver consumption while maintaining key performance indicators such as temperature rise, breaking capacity, and electrical life. |
