Flux density soft-magnetic material

We have a wide line up of iron-based soft-magnetic materials, such as free-cutting pure iron / silicon iron with excellent magnetic properties,high saturation flux density materials, and high-permeability magnetic materials.

Features

Compared with common soft-magnetic iron:

  • Free-cutting pure iron (ME1F): Soft-magnetic and high cold forgeability
  • Free-cutting TICS 2.2% silicon iron (MES2CS): Lead-free free-cutting
  • Free-cutting 3% silicon iron (MES3F): High resistance and soft-magnetic
  • Permendur (K-MP11): The largest saturation magnetic flux density

【Usage】

Motors, relays, resolvers, magnetic actuators
