REalloys Demonstrates HF-Free Fluorination Reducing Oxygen to 0.34%
REalloys demonstrated an HF-free process producing metallization-grade rare earth fluoride feedstock with oxygen content of 0.34% at its Euclid, Ohio plant. USA Rare Earth is among the few firms, alongside MP Materials and Lynas, racing to rebuild domestic magnet production capacity.
1. REalloys Demonstrates HF-Free Fluorination Breakthrough
REalloys has successfully removed hydrofluoric acid from its rare earth fluorination stage, producing metallization-grade feedstock with just 0.34% oxygen—well below the 1% threshold for metal production. The process, developed at its Euclid, Ohio facility, replaces one of the most hazardous inputs in rare earth metallurgy, promising lower environmental and safety burdens.
2. Implications for USA Rare Earth's Magnet Production Efforts
As REalloys advances fluorination upstream, USA Rare Earth and peers like MP Materials and Lynas face increased pressure to scale their own metallization and magnet alloy integration capabilities. The development underscores the urgent need to rebuild a full-stack, domestic rare earth supply chain to support defense, aerospace and EV industries and could influence USA Rare Earth's strategic priorities.
