Same Terbium, Higher Coercivity: What New Grain Boundary Diffusion Research Means for NdFeB Manufacturing
A study published this year in Applied Physics A raised the coercivity of a grain boundary diffused NdFeB magnet from 17.81 kOe to 26.47 kOe by using a terbium and copper mixed powder as the diffusion source, compared with 24.09 kOe for pure terbium hydride, under identical diffusion conditions and the same terbium dosage. Both […]
Magnet Engineering Takes a Larger Role in Commercial NdFeB Production
As demand for neodymium-iron-boron permanent magnets expands across electric mobility, wind energy, industrial automation, electronics, and other advanced applications, manufacturers are placing greater emphasis on the connection between product engineering and repeatable commercial production. NIST research identifies electric vehicles and wind turbines among the technologies driving demand for rare earth permanent magnets, while the U.S. […]
