Fe\u2013N magnets may offer a credible substitute in lower- and mid-performance markets\u2014appliances, industrial motors, auxiliary automotive systems\u2014and success here could meaningfully reduce U.S. dependence on NdPr and heavy REEs where supply risk is acute. Yet nothing in today\u2019s data suggests Fe\u2013N can displace high-coercivity NdFeB magnets used in EV drivetrains, precision defense actuators, or high-temperature aerospace platforms. The hardest categories\u2014those that run the spine of the Pentagon\u2019s war-fighting capability\u2014still live and die on NdFeB, often dysprosium-doped.
