World-first Iron Nitride permanent magnet facility set to be built in US

Niron Magnetics, a US-based company, is set to build the world’s first full-scale manufacturing facility for Iron Nitride permanent magnets in Sartell, Minnesota, with operations expected to begin in early 2027. The new 190,000-square-foot plant will have an annual production capacity of 1,500 tons of these magnets, which are made from abundant and domestically sourced iron and nitrogen rather than rare earth materials. This breakthrough technology aims to create a resilient and sustainable US supply chain for permanent magnets critical to industries such as automotive, defense, industrial motors, consumer electronics, and renewable energy. The project, managed by Wood under an engineering, procurement, and construction management (EPCM) contract, represents a significant advancement in sustainable magnet production at scale. Niron Magnetics’ Iron Nitride magnets offer high magnetization without relying on rare earth elements, reducing supply chain vulnerabilities and environmental impacts associated with traditional magnet manufacturing. The Sartell facility builds on the success of a pilot plant
