World's first manufacturing plant for rare-earth-free magnets opening in Minneapolis. Approximately 90% of the world's industrial permanent magnets are produced in China, leaving the supply chain open to significant disruption with environmental, economic, or national security risks. Permanent magnets containing neodymium and other rare earth elements are essential components in a wide variety of technologies and industries, including MRI machines, electric vehicles, wind...
Researchers from the U.S. Department of Energy's Critical Materials Institute, led by Ames National Laboratory, have developed a "Hot-roll Nano Neo Magnet" method for manufacturing high-performance neodymium-iron-boron permanent magnets that are heat-resistant, easier, and greener to produce. Neodymium is a rare earth metal that tarnishes rapidly when exposed to air. In 1983, it was discovered that when alloyed with iron and boron, it would create a magnetic force 10 times...
Scientists at the United States Department of Energy Princeton Plasma Physics Laboratory (PPPL) have designed a new type of magnet made from niobium and tin that could aid devices ranging from tokamaks to x-ray machines. In a recent experiment that shattered its old record, researchers at the Joint European Torus (JET) facility reported producing 59 megajoules of energy over five seconds with the holy grail of energy, fusion – more than doubling the facility's previous r...
Researchers at the University of Pittsburgh Swanson School of Engineering are working with Powdermet Inc., an Ohio-based nanomaterials and advanced materials research and development company, to develop manganese-bismuth-based materials as an alternative to rare earths in permanent magnets. The motors in most electric vehicles made today contain rare earth permanent magnets, which leverage the naturally occurring strong magnetic force offered by rare earths such as neodymium o...
