Electrical Contact Materials
What is "Electrical Contact Materials"
Electrical Contact Materials are cadmium-free silver–metal oxide alloys, including Ag–SnO₂, Ag–ZnO, and Ag–Ni. Fine oxide particles are uniformly dispersed within the silver matrix to provide stable contact resistance along with improved anti-welding performance and wear resistance. In addition to high reliability, these materials support device miniaturization and cost optimization, and are widely used in relays, switches, and other electrical contact applications.
We offer silver-oxide-based cadmium-free contact materials.
They can be used for a wide range of applications.
Fine oxide particles are evenly dispersed in contact materials for relays and switches to improve durability and contact reliability. Upon your request, we offer these silver oxide contacts in various shapes such as rivet contacts and crossbar contacts.
Features
- Stable contact resistance through uniform dispersion of oxides
- Improved durability through excellent welding resistance
- Excellent wear resistance andand even erosion patterns have enabled lighter, thinner, and smaller contacts and contributed to a reduction in costs.
