CMI researchers from Ames National Laboratory conducted the activity for this highlight

Innovation  
Modeling demonstration that CMI hot-rolled (HR) magnets (without dysprosium) are a viable alternative to dysprosium-containing NdFeB magnets for medical applications.

Achievement

  • Performance of HR magnets matches or exceeds that of N38SH magnets in biomagnetic separators.
  • HR magnets demonstrate up to 3% higher magnetic field output compared to currently employed N38SH.

Significance and impact  
Acceleration of commercial deployment and broadening commercialization prospects for CMI magnets.  Reduction of reliance on critical dysprosium.

Hub Goal Addressed  
Prototyping of REE-reduced permanent magnets.
