# Niron Magnetics

**Type:** Company  
**Domain:** Robotics, Manufacturing  
**Focus:** Iron nitride (Fe16N2) permanent magnet development and production

## Overview

Niron Magnetics develops iron nitride permanent magnets as a rare-earth-free alternative to neodymium-iron-boron (NdFeB) magnets. The company's Fe16N2 technology approaches NdFeB performance levels without requiring rare earth elements.

## Timeline

- **2025-01** — Demonstrated iron nitride magnet prototype at CES 2025 in partnership with MATTER Motor Works (variable flux motor application)
- **2027** (projected) — Sartell, Minnesota production plant to reach 1,500 tons/year capacity

## Significance

Represents the nearest-term viable rare-earth-free alternative for high-performance robot actuators, though production scale remains insufficient to meet aggregate humanoid robot industry demand through late 2020s.
