ADVANTAGES

Grain boundary diffusion

晶界扩散技术 可减少稀土(镝/铽)的使用量,有效节约重稀土资源,降低磁体的生产成本,提高高档钕磁体的综合性价比。

对于同等级的磁体,与传统工艺相比,GBD工艺使用的重稀土(HREE)较少,可制得具有较高综合性价比的磁体,如52SH、52UH、45EH、42AH、38等,其中部分Hcj(kOe)+(BH)max(MGOe)>82。

Advantage

  • 01

    Uses less Dy/Tb; e.g., 80% of DyFe can be reduced in the production of 45UH

  • 02

    With dysprosium and terbium-free technology to produce cost-effective GBD products

  • 03

    Coercivity improved by 2-3 grades, Hcj improved from 12 KOe to 25-26 KOe

  • 04

    We've already started mass production of 52UH. Ultra-high grades 54UH 50EH can be produced

  • HREE Free
  • Traditional Method

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

  • Trad.+GBD
  • GBD
  • Under Developing

    58SH,56UH,52EH
