# 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.
