Iron Nitride Breakthrough Challenges Global Rare Earth Dependency
Niron Magnetics has begun construction on a rare earth-free magnet plant in Sartell, Minnesota. The $275 million facility will produce 1,500 tons per year of iron nitride-based permanent magnets. Unlike traditional magnets made with neodymium or dysprosium, Niron’s products use abundant elements like iron and nitrogen. As a result, this development marks a major step toward reshoring magnet production and reducing reliance on critical rare earth imports.
Major Industry Partners Back Iron Nitride Scale-Up
Niron’s patented process stems from years of R&D with the U.S. Department of Energy and University of Minnesota. Commercial partners include Stellantis, Samsung, Allison Transmission, and Magna—all currently sampling products from Niron’s pilot line. These rare earth-free magnets target diverse markets such as electric vehicles, robotics, data centers, and defense applications. In contrast to rare earth-dependent magnets, iron nitride offers high magnetization without geopolitical risk.
Strategic Implications for U.S. Magnet Supply Chain
The Sartell site will revive a former coal community asset and create over 175 full-time jobs by 2027. Meanwhile, rare earth supply chains face mounting strain due to China-centric concentration and EV demand spikes. Therefore, Niron’s rare earth-free magnet technology could redefine sourcing strategies for OEMs and recyclers. This aligns with U.S. policy goals of critical material independence and sustainable manufacturing practices.
ScrapInsight Commentary
Niron’s iron nitride breakthrough could disrupt rare earth demand in key magnet applications. If scaled successfully, recyclers may pivot away from rare earth recovery in favor of abundant element processing. Policy-driven incentives and OEM commitments will determine the long-term impact on magnet material flows and scrap valuation.
