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。
Uses less Dy/Tb; e.g., 80% of DyFe can be reduced in the production of 45UH
With dysprosium and terbium-free technology to produce cost-effective GBD products
Coercivity improved by 2-3 grades, Hcj improved from 12 KOe to 25-26 KOe
We've already started mass production of 52UH. Ultra-high grades 54UH 50EH can be produced
*GBD is available but traditional method’s price is better
58SH,56UH,52EH
