| Materials | Applications | Solutions |
| AgWC Powder Metallurgy Contact Tips | Miniature Circuit Breakers (MCBs) | ① Advanced cladding process for uniform, stable microstructure ② Strong arc-erosion resistance and anti-weld performance, maintaining low contact resistance and controlled temperature rise for longer electrical life |
| BAg72Cu Brazing Materials | Industrial Fuses | ① Tight thickness tolerance and stable electrical resistance ② Good mechanical strength and formability for consistent manufacturing and reliable fuse performance |
| FAg / AgNi10 Powder Metallurgy Contact Tips | AC Contactors, Signal Relays | ① Reduces bulk resistivity by ~0.2 μΩ·cm vs conventional materials, resulting in lower contact temperature rise and improved operational stability |
| AgSnO₂ Contact Tips | AC Contactors | ① Strong interfacial bonding, withstanding repeated arcing with reduced spatter or pitting ② Stable contact resistance with minimal fluctuation and strong anti-weld performance ③ High reliability, greener material |
