Honda Motor Invests in Niron Magnetics-Iron Nitride Enters the Automotive Qualification Race

Highlights

• Honda Motor invested an undisclosed amount in Niron Magnetics on September 9, 2026, targeting rare-earth-free iron nitride permanent magnets.
• Iron nitride must still prove coercivity, thermal stability, manufacturing yield, and cost competitiveness across automotive duty cycles before replacing NdFeB magnets.
• Niron targets 1,500 tons annually at its Sartell, Minnesota pilot plant, but neither that target nor Honda's investment confirms mass-production economics.
• Honda's move follows a broader automaker trend of building multiple supply-chain escape routes combining alternative magnets, magnet-free motors, and recycling.
• REEx concludes this is a strategically meaningful development project, not an offtake commitment or proof that rare-earth-free motors are near broad scale.
