SIE Series

By adding the third and fourth elements like indium, etc., the formation of oxide films on the alloy surface is controlled in the process of internal oxidation, and solute concentration capable of internal oxidizing becomes high, enabling us to easily scatter large quantities of oxides. SIE series have superior resistance to welding and wear and are adopted widely in multi-purpose relays and switches as well as for various automotive uses.
