What is Rare Earth Magnet

Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and thenground or sliced into the desired shape. Coatings are then applied if required. Finally, the

blank magnets are magnetized by exposing them to a very powerful magnetic field in excess

of 30 KOe.

Brief Introduction

  • 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.
