Honda Motor has invested in US-based company Niron Magnetics, which focuses on the commercialization of rare-earth-free iron nitride permanent magnet materials. The investment, announced on September 9, aims to support the ongoing commercialization of Niron's technology and help expand its manufacturing operations. This move reflects Honda's interest in next-generation magnetic materials that help reduce the reliance of electrified systems on rare-earth elements.
The Potential of Rare-Earth-Free Materials
Reducing reliance on rare-earth materialsPermanent magnets are used in electric propulsion motors and a variety of other technologies. However, many traditional high-performance magnets rely on rare-earth metals that face resource constraints and changing market conditions. Niron's iron nitride technology offers a rare-earth-free alternative designed to support performance, cost stability, and sustainability goals while reducing dependence on global supply chains. "This investment reflects growing manufacturer interest in rare-earth-free magnetic technology as they seek more resilient solutions," said Jonathan Rowntree, CEO of Niron Magnetics.
He added, "Following Honda's investment, we are excited about their confidence in our technology and their vision to expand the application of rare-earth-free permanent magnets."
The technology can be applied in automotive systems, robotics, industrial automation, and emerging mobility platforms, with other potential applications including AI and data center infrastructure as well as consumer electronics. Honda is optimistic about the potential of electric propulsion technology. Currently, most electric propulsion motors use permanent magnets made from rare-earth metals. Honda expects Niron's technology to help address some of the supply and market challenges associated with these materials. Mahito Shikama, Executive Director of Honda Motor Co., Ltd., said, "Niron Magnetics has an innovative permanent magnet technology that does not require rare-earth materials."
He added, "Currently, most electric propulsion motors use permanent magnets made from rare-earth metals, which are subject to resource constraints and market condition fluctuations." He further stated, "Niron Magnetics is addressing these challenges, and Honda is excited about its potential."
The Significance of Honda's Investment
The investment further supports Niron's efforts to establish iron nitride as a new class of permanent magnet materials. It will also help the company expand the adoption of its technology in an increasing range of products and applications. Honda's support strengthens the shift of resources toward alternative rare-earth-based permanent magnets. For Niron, it supports its transition from commercializing technology to mass-producing magnets.
Niron recently announced the construction of a 287,000-square-foot magnet manufacturing facility in Sartell, Minnesota. The plant is scheduled to begin operations in 2027. Once operational, the facility is expected to produce up to 1,500 tons of rare-earth-free iron nitride permanent magnets annually. This output will serve the automotive, industrial, and advanced technology applications the company is targeting. The facility is a core part of Niron's manufacturing expansion. Honda's investment will support the company's work in expanding production and promoting the application of iron nitride magnets in electrification systems.
Honda Investment Drives Development of Rare-Earth-Free Technology
Honda's investment demonstrates a commitment to rare-earth-free permanent magnet technology, which not only reduces reliance on rare-earth metals but also enhances the sustainability of electric propulsion systems. As global environmental requirements increase, the development of rare-earth-free materials is crucial for the automotive and other high-tech industries. Niron's iron nitride technology is expected to become an important option in future markets, helping manufacturers address resource constraints and market fluctuation challenges, thereby promoting the widespread application of the technology.
