Niron Magnetics
Type: Company
Domain: Manufacturing (Permanent Magnets)
Status: Active
Founded: ~2016 (based on University of Minnesota research)
Location: Minneapolis, Minnesota (pilot plant); Sartell, Minnesota (commercial plant under construction)
Overview
Niron Magnetics is developing commercial iron nitride (Fe16N2) permanent magnets as a rare-earth-free alternative to neodymium-iron-boron (NdFeB) magnets. The technology is based on research by Professor Jian-Ping Wang at the University of Minnesota.
Technology
Iron Nitride (Fe16N2) Permanent Magnets:
- Made from iron and nitrogen—two of Earth's most abundant elements
- No rare earth elements required
- Claims to approach NdFeB energy product performance
- Higher temperature operation capability than ferrite alternatives
- Key differentiation: closes more of the performance gap to NdFeB than ferrite does
Facilities
Minneapolis Pilot Plant:
- Opened: October 2024
- Purpose: Commercial sampling and pilot production
- Funding: ARPA-E supported early pilot work
Sartell Commercial Plant (Plant 1):
- Groundbreaking: September 29, 2025
- Expected operational: 2027
- Annual capacity: 1,500 metric tons of iron nitride permanent magnets
- Significance: World's first commercial iron nitride magnet manufacturing facility
Product Validation
CES 2025 Motor Prototype:
- Partnership with MATTER Motor Works
- Demonstrated: Rare-earth-free variable flux motor prototype
- First working motor demonstration using iron nitride magnets for industrial applications
- Date: January 2025
Market Context
- Global NdFeB production: ~200,000 metric tons/year (predominantly China)
- Niron's 2027 capacity (1,500 tons/year) = 0.75% of current global NdFeB market
- Sufficient for approximately 430,000 humanoid robots annually (at 3.5 kg NdFeB-equivalent per robot)
Strategic Significance
Niron Magnetics represents the only near-term path to rare-earth-free permanent magnets for high-performance applications including humanoid robot actuators. The 2027 operational timeline means the technology cannot address 2025-2026 production constraints but could begin resolving China's rare-earth supply chain leverage from 2027 onward.
