2J83, 2J84, 2J85 Wrought Iron-Chromium-Cobalt Permenent Magnet Alloys

Iron-chromium-cobalt permanent magnet alloy not only has good ductility, but also has good magnetic properties. It is the most widely used deformable permanent magnet material at present. Its magnetic properties are comparable to cast aluminum nickel cobalt alloy, and the price is cheaper than iron cobalt vanadium permanent magnet alloy. The alloy is characterized by homogeneous composition, compact structure and stable performance. It can replace some cast Al-Ni-Co alloys and Fe-Co-V alloys to make complex permanent magnet components.

Characters

  • Heat resistant: magnetism does not decline below 400 degrees
  • Can be machined, such as cutting, tapping, drilling, stamping, etc.
  • Impact resistance while other magnetic materials are fragile and easy to crack.
  • Magnetic requirements can be adjusted according to customer needs (semi hard magnetic properties can be made).
  • Good corrosion resistance

Magnetic properties

Grade Type Br/T Hc(kA/m) (B·H)max/(kJ/m3)
