Grain boundary diffusion

Grain boundary diffusion technology Can reduce the use volume of the rare earth (dysprosium /terbium) so that it can save the heavy rare earth resource effectively, and decreases the production cost of the magnet as well as enhance the comprehensive cost performance of high grade neodymium magnet.

Aiming at the magnets with same grade, compared with traditional technology, GBD technology uses less (HREE) Heavy rare earth and this technology can make the magnet with higher comprehensive cost performance, like 52SH, 52UH, 45EH, 42AH, 38TH, part of them Hcj(kOe)+(BH)max(MGOe)>82.

  • A

    Uses less HREE Dy/Tb to increase Hcj

  • Can produce cost-effective Neodymium magnets

  • C

    Leading technology for PVD manufacturing process

  • Can achieve super higher property such as 54UH,50EH,etc.

  • HREE Free
  • Traditional Method

    *GBD is available but traditional method’s price is better

  • Trad.+GBD
  • GBD
  • Under Developing
