Silver Tungsten Carbide Contacts, AgWC contacts

HOSOMETAL uses the advanced Vacuum Infiltration process make the AgWC contacts. The material has high arc resistance, low chopping currents and long service life.

Comparing to the silver tungsten, the silver tungsten the advantage of releasing CO to restrain tungsten oxide, thus with longer life.
