Jun Cui at Ames Laboratory leads the CMI project "Application targeted magnetic materials"
This project strives to bridge CMI’s magnet research to manufacturing. Several magnet compositions have been identified via CMI’s discovery effort. These magnets use less than half of the neodymium (Nd) in the conventional neodymium-iron-boron (NdFeB) magnet. Although they are less powerful, they can be used in many applications less demanding on energy product, thereby reduce Nd supply risk. The project will push CMI’s discovery effort one step further, to scale the newly discovered compositions up from the current powder form to sintered bulk magnet. The deliverable will be a set of processes that can be adopted by industry for manufacturing these gap magnets.
