Niron Magnetics Begins Site Selection for $1.8B Magnetics Plant

Why It Matters

Domestic production of rare‑earth‑free permanent magnets strengthens U.S. supply‑chain resilience and reduces dependence on China’s rare‑earth exports, a critical factor for defense and clean‑energy technologies.

Key Takeaways

• Plant worth $1.8 billion, 1.6 M sq ft facility.
• Will produce up to 10,000 tons of iron‑nitride magnets annually.
• Creates 700+ jobs, supports 2% of global magnet market.
• Second U.S. site follows $169.7 M Minnesota plant.
• Focuses on rare‑earth‑free magnets, reducing supply‑chain risk.

Pulse Analysis

The global demand for permanent magnets has surged as electric vehicles, renewable‑energy turbines and advanced robotics become mainstream. Traditionally, the industry has relied on rare‑earth minerals sourced primarily from China, exposing manufacturers to geopolitical risk and price volatility. Niron Magnetics, founded in 2013 through a partnership with the U.S. Department of Energy and the University of Minnesota, has pioneered iron‑nitride, rare‑earth‑free magnet technology that delivers comparable performance without the supply‑chain constraints. Its pilot plant in Minneapolis, opened in 2024, demonstrated the commercial viability of this approach and set the stage for larger‑scale production.

The upcoming $1.8 billion facility represents Niron’s most ambitious U.S. investment to date. Spanning 1.6 million sq ft, the plant is designed to output up to 10,000 tons of iron‑nitride magnets annually—enough to cover roughly two percent of worldwide permanent‑magnet consumption. By creating more than 700 skilled jobs and leveraging existing infrastructure, the project promises a multiplier effect for local economies, especially in regions that meet the company’s criteria for transportation access, reliable power and a ready workforce. The site‑selection process, guided by real‑estate advisor Savills, underscores the strategic importance of locating the plant near key industrial corridors.

Beyond the immediate economic boost, the plant advances U.S. policy goals of reshoring critical materials and reducing reliance on foreign rare‑earth supplies. As Congress tightens export controls on Chinese minerals, manufacturers of electric‑drive motors, defense systems and data‑center cooling equipment will increasingly seek domestically sourced, rare‑earth‑free alternatives. Niron’s expansion, together with its earlier $169.7 million Sartell plant, positions the United States to capture a larger share of the high‑growth magnet market while fostering innovation in sustainable, low‑cost magnetic materials. The initiative signals a broader shift toward resilient, home‑grown supply chains in the clean‑technology era.
