CMI Highlight: Patent granted for hot-roll nano-neo magnet technology
CMI researchers at Ames National Laboratory conducted the research for this highlight
Innovation
Hot-roll Nano-Neo technology offers a viable technique for producing HREE-free high-temperature NdFeB grades.
Achievement
The U.S. Patent and Trademark Office granted the patent “Near-Net-Shape Fabrication of Anisotropic Magnets Using a Hot-Roll Process.”
Significance and impact
The technology enables cost-effective manufacturing of HRE-free magnets operating at elevated temperatures (~180°C), and reduced manufacturing waste through near-net-shape processing. The patent strengthens the team's position for industry engagement and creates opportunities to collaborate with magnet manufacturers and end users.
Hub Target Addressed
Magnet maturation and deployment.
