Cadmium Free Electric Contact Materials
We supply three types of Ag-SnO system contact materials, which are environmentally friendly.

FE Series
FE130 and FE160 contact materials are produced with our proprietary technology, enabling us to scatter highly concentrated fine SnO uniformly into silvery, despite a pre-oxidation method. The materials have superior welding and wear resistance and are adopted widely in multi-purpose relays and switches, etc, as well as for various automotive uses.Types and Properties of FE Series
