+# Niron Magnetics
+
+**Type:** Materials technology company  
+**Focus:** Iron nitride (Fe16N2) permanent magnets as rare-earth-free alternative to NdFeB  
+**Status:** Pilot production phase  
+
+## Overview
+
+Niron Magnetics develops iron nitride permanent magnet technology that approaches neodymium-iron-boron (NdFeB) performance without rare-earth elements. The company's Fe16N2 magnets target applications in electric vehicle motors and high-performance actuators where rare-earth supply chain constraints create strategic vulnerabilities.
+
+## Timeline
+
+- **2025-01** — CES 2025: Demonstrated iron nitride magnet prototype in variable flux motor partnership with MATTER Motor Works, showing performance approaching NdFeB
+- **2027** (projected) — Sartell, Minnesota production facility targets 1,500 tons per year capacity
+
+## Technology
+
+**Iron Nitride (Fe16N2) Magnets:**
+- Performance claims approach NdFeB energy density
+- Rare-earth-free composition eliminates geopolitical supply chain dependency
+- Suitable for high-torque applications including humanoid robot actuators
+- Production scaling timeline: 1,500 tons/year by 2027 (insufficient for mass market deployment across multiple manufacturers)
+
+## Market Position
+
+Niron represents the earliest viable rare-earth-free alternative for high-performance permanent magnet applications, but production capacity lags demand by 5-8 years. Industry analysis indicates substitution will "lag demand this decade" as electrification and automation expand faster than alternative magnet production scales.
