Rare Earth Magnets: Yesterday, Today and Tomorrow
Click Here to view the complete presentation Rare Earth Magnets: Yesterday, Today and Tomorrow.
Dr. John Ormerod, Magnet Applications Senior Technical Advisor, originally presented this Webinar on Tuesday, October 30, 2018.
The global permanent magnet market is dominated by rare earth magnets based on the Nd2Fe14B phase accounting for over 60% of total magnet sales. The historical development of rare earth magnets will be overviewed. The current status of material development and processing technologies will be reviewed. With the forecast growth in applications e.g. in both ICE and HEV/EV markets, the search for alternatives to the current Nd, Pr and Dy alloy compositions is being pursued. Also, microstructure engineering through thermomechanical processing is being developed to enhance magnetic performance with lower rare earth content. These technologies and market drivers for the rare earth magnet industry will be discussed. Finally, an alternative approach to the “gap magnet” opportunity will be covered.
Dr. John Ormerod graduated from the University of Manchester, UK with a BSc, MSc and PhD in Metallurgy. He has over twenty years of research, product development, and manufacturing experience in the area of permanent magnets and magnetic materials. He has published and presented numerous papers in the field of magnetic materials. In 2015 John founded JOC LLC, a consultancy specializing in the magnetics and metals-related industries. He serves on the Advisory Board of Bunting Magnetics Company and is Senior Technology Advisor to Magnet Applications, Inc. and Technology Advisor to Niron Magnetics.
