Summary
Niron Magnetics is developing a new class of rare-earth-free permanent magnet based on iron nitride, pitched as scalable, domestically manufactured material for motion. Its website says a commercial pilot plant in Minneapolis, Minnesota is actively manufacturing and sampling customers, a 1,500 tons-per-year plant in Sartell, MN is listed as ground broken, and a 10,000 tons-per-year high-volume plant is planned with site selection underway. Target markets include robotics and automation and industrial motors and generators alongside mobility, aerospace and defense, thermal management, audio and AI infrastructure. If it scales, it is a structural alternative to the NdFeB dependence documented in the Actuators supply-chain notes; today the evidence is pilot-scale and company-sourced.
