But behind this growth are some practical contact-level challenges:
1. 24/7 operation and frequent switching drive arc erosion, leading to false trips and failures.
2. High contact resistance wastes energy as heat and hurts thermal performance.
3. Compact devices require strict tolerances, complex geometries that traditional processes struggle to deliver.
4. IoT devices rely on clean low-voltage signals; contacts must stay sensitive, low-bounce, and stable.
To address these challenges, Fudar Alloy provides high-performance powder metallurgy (PM) contact solutions:
1. Reliability & Lifetime – Optimized PM formulations improve arc-erosion resistance and mechanical strength (≥350 MPa), enabling 20,000+ operations and fewer failures.
2. Higher Energy Efficiency – PM contact materials deliver an excellent balance of electrical and thermal conductivity, with very low initial contact resistance (≤0.4mΩ) to reduce losses and heat.
3. Miniaturization & Integration – PM technology provides precise, complex contact geometries, supporting more compact, highly integrated device designs.
4. Stable Signal Performance – Controlled grain structure and surface state ensure a consistent contact interface, while high surge current endurance (up to 12,000 A) helps suppress bounce, noise, and signal jitter.
Our high-quality
components are already designed into MCCBs, MCBs, ACBs, magnetic latching relays, switches, and smart home appliance controls across modern buildings.
Fudar Alloy is committed to advancing electrical contact technologies that make
smart buildings and homes safer, more efficient, and more comfortable for the people who live and work in them.
