Electrical Contact Materials for HV DC Relays & Contactors
Fudar Alloy has developed a core component portfolio for EV high-voltage DC systems, including riveted contact assemblies, moving and stationary contacts, iron cores, and Kovar frame plates. These components are engineered to withstand the high arc energy, thermal loads, and switching frequencies typical of such applications. Our AgSnO₂ and AgCuO contact materials provide excellent arc erosion resistance and thermal stability, enabling reliable performance in high-voltage DC relays and contactors over hundreds of thousands of switching cycles. From material development to finished components, our fully integrated production process ensures consistent dimensional accuracy and tightly controlled electrical resistivity.
