Moog and Niron Magnetics will showcase their rare-earth-free actuator solutions at the Association of the United States Army (AUSA) 2026 Annual Meeting and Exposition in Washington, D.C., in October.

At the event, the companies plan to demonstrate their work using Niron’s Iron Nitride permanent magnets, which convert electrical signals into mechanical motion. The promising technology is being tested for applications including land vehicles and guided munitions.

“The Army is transforming quickly, and the systems soldiers rely on can only move as fast as the supply chains behind them,” said Ryan Aures, Moog Land and Sea Systems engineering director, in a press release. “Our work with Niron is about making sure a disruption never stands between the warfighter and the capability they need.”

The project builds on a collaboration between Moog and Niron announced in December 2025. Moog is testing and qualifying Niron’s Iron Nitride permanent magnets in electromechanical actuators, which would reduce dependency on critical minerals – an innovative solution to a global problem.

Iron Nitride removes rare earth elements

Almost every precision system the Army depends on contains rare earth. “Today almost all of that supply runs through a single foreign source,” said Jonathan Rowntree, CEO of Niron Magnetics.

According to an October 2025 report from the Council on Foreign Relations (CFR), “China controls up to 90 percent of the world’s critical-mineral processing capacity, including more than 99 percent of processing for three rare earths needed for heat-resistant magnets,” CFR said.

Niron claims that its Iron Nitride technology can produce permanent magnets without rare earth materials–which would eliminate the problem in a world scrambling to move manufacturing to domestic soil.

Critical minerals are used in products ranging from smartphones and vehicles to advanced weapons systems including the F-35.

US moves to expand domestic magnet supply

The U.S. government has also taken steps to expand domestic rare-earth production. According to CFR, the Department of Defense took a 15 percent stake in U.S.-based rare-earth producer MP Materials for $400 million in July 2025.

The Moog-Niron project takes a different approach by developing permanent magnets that do not require rare-earth materials, which would be the ultimate shutdown response to the entire situation if the Army just eliminated the need.

According to the company’s release, Niron has been producing Iron Nitride magnets and conducting customer qualification since 2025. The company expects to begin commercial production within the next 18 months.

Niron says its magnets are already being used in applications spanning artificial intelligence infrastructure, automotive products, industrial equipment and consumer electronics.

For the defense project, Moog is testing and qualifying the magnets specifically in electromechanical actuator systems.

Technology headed to AUSA 2026

The companies will jointly present the technology at Moog’s booth during AUSA 2026. Moog and Niron plan to display Iron Nitride magnets installed in tested motor hardware. The companies said attendees can also speak with engineers about integration, qualification timelines, and supply availability.

Niron, meanwhile, is working to commercialize its Iron Nitride permanent magnets through its proprietary manufacturing platform.
