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.
HOSO Metal silver tungsten carbide block:
HOSOPM® 3 series product use the Infiltration process to make gas contents low with O2<50ppm, N2<20ppm and H2<5ppm.
