Features of Ndfeb magnet:

  • Chemical Composition: Nd2Fe14B.

Neodymium magnets are hard, brittle and easily corrode.

  • Moderate Temperature Stability.

They are working stability under 80°C for low Hci and can reach 200°C highest working temperature for high Hci.

  • Excellent strength value.

The highest (BH)max reaches up to 51MGOe .

  • Advanced Technology.

It choose Strip casting and HDDR technology allows us to make high performance NdFeB over N52 possible.

  • Effective Surface Treatment to Prevent Corrosion.

Surface treatments have been developed that allow them to be used in most applications. The treatments include gold, nickel, zinc, tin plating and epoxy resin coating.
