CMI researchers at Ames National Laboratory and Oak Ridge National Laboratory conducted the research for this highlight
Innovation
High performance magnets via combination of NeFeB and SmFeN powders of distinct sizes.
Achievement
Magfine anisotropic NdFeB (100 mm) and SmFeN (4 mm) powder packing in polyphenylene sulfide (PPS) polymer results in high performance (20 MG-Oe) bonded NdFeB magnets.
Significance and Impact
- Reduced cost, 40% reduced-Nd bonded magnet outperforms conventional NdFeB bonded magnets.
- Calculations predict further improvement of BHmax by maximizing the filling fraction of coarse and fine magnetic powders.
Hub Target Addressed
Industrial adoption of CMI technologies.
