About
Niron Magnetics is building the first domestically manufactured, rare-earth-free permanent magnet platform, engineered for industrial performance and long-term supply independence.
About Us
We’re building a new material foundation for modern machines
Niron Magnetics is a U.S.-based advanced manufacturing company commercializing the world’s first high-performance, rare-earth-free permanent magnets using Iron Nitride. We build scalable domestic alternatives to rare earth materials, engineered for industrial-grade performance and long-term reliability.
We combine materials science innovation with disciplined manufacturing execution, translating laboratory breakthroughs into repeatable, high-volume production processes. From commodity feedstocks to finished magnets, we operate the full production chain under one roof.
Our Values
Sustainability
We build from abundant, domestically sourced feedstocks, reducing risks to health and environments produced by rare earth mining, and emphasizing sustainable manufacturing practices at every stage of production.
Innovation
We push the boundaries of materials science and manufacturing process design to accelerate and empower materials innovation.
Teamwork
We hold ourselves and each other to high standards of safety, rigor, and accountability, because the work we’re doing demands it.
Results
We measure success in production milestones, customer validation, and real world performance, where success is non-negotiable.

Platform Advantages
Built differently. From the material up.
Engineered to Excel
Deliver next-generation performance with magnets built for motor efficiency, thermal stability, and the demands of advanced electrified systems.
Dedicated Application Support
Work directly with our engineers and laboratory team to test, characterize, and integrate Iron Nitride magnets into your specific application.
150+ Patents and Counting
Draw on the world’s largest Iron Nitride IP portfolio and deep materials science expertise, built over a decade of turning laboratory breakthroughs into rare-earth-free permanent magnets.
Sustainable Manufacturing
A more human-friendly process uses fewer resources, respects air and waterways, and draws on abundant domestic inputs without the global extraction and processing chains rare earth magnets depend on.
Leadership
“Iron Nitride is a new magnet for a new century that no foreign power can monopolize or restrict.”
