The breakthrough targets an urgent stage in the production of rare earth metals, the materials that ultimately feed the permanent magnets used in fighter aircraft, missile systems, radar platforms, robotics, electric vehicles, and advanced computing systems.
It also comes amid a looming 2027 ban on Chinese-origin rare earth materials, instituted out of desperation as the U.S. and allies race to rebuild rare earth processing capacity after decades of monopolization and weaponization by Beijing.
Only a small number of companies in North America are attempting to rebuild those capabilities.
REalloys is one of them.
From its metallization platform in Euclid, Ohio, the company converts rare earth oxides into finished metals and magnet alloys used by manufacturers supplying the defense industrial base and advanced industrial markets.
The new fluorination technology expands that platform further upstream.
REalloys said independent laboratory testing confirmed that its HF-free process can produce metallization-grade rare earth fluoride feedstock with oxygen content of 0.34 weight percent—well below the 1 percent threshold typically required for rare earth metal production.
“Hydrofluoric acid has been necessary for rare earth metallization, until now,” said Lipi Sternheim, chief executive officer of REalloys. “We believe this breakthrough can significantly reduce the environmental burden, safety risks, and costs traditionally associated with this critical step of rare earth processing while helping enable cleaner rare earth metal production in the United States.”
Rare earth fluorides are the intermediate material used to produce metals such as dysprosium, terbium, and neodymium—elements that strengthen the high-performance permanent magnets used across modern defense systems, aerospace platforms, and advanced industrial technologies.
Scaled, this process could remove one of the most hazardous chemical steps from rare earth metal production while expanding the ability to manufacture these materials within North America.
Rebuilding The US Rare Earth Supply Chain-Cleaner
For years, the Western response to rare earth dependence focused on mining and separation. Mountain Pass restarted. New separation plants began appearing in North America. Oxides such as neodymium-praseodymium can now once again be produced domestically.
But oxides themselves don’t power the civilian economy and the American defense industry: rare earth metal alloys do. That’s the missing link in the chain that REalloys is now providing–and scaling.
Before those rare earths can power a missile guidance system or a wind turbine generator, they must be transformed into rare earth metals. Those metals are then blended into precise alloys that feed the permanent magnets inside fighter aircraft, radar systems, robotics, electric vehicles, and advanced computing hardware.
That transformation—from oxide to metal—is the true industrial chokepoint.
That gap between oxide production and usable metal has created a narrow field of companies attempting to rebuild the full stack of rare earth capability outside China. MP Materials (NYSE: MP) has restarted upstream production at Mountain Pass, Lynas Rare Earths (OTC: LYSDY) continues to expand separation capacity, and USA Rare Earth (NASDAQ: USAR) is working to integrate magnet production domestically.
And for decades, Beijing has enjoyed a weaponizable monopoly on nearly every part of the rare earth supply chain.
Even when rare earth ore was mined in the United States and separated domestically, the metallurgical conversion that turns those oxides into usable metal was still performed overseas. The expertise, equipment, and operating experience migrated there over time.
Rebuilding that capability is far more complex than reopening a mine.
Metallization requires tightly controlled reduction reactions, specialized high-temperature furnaces, and process control systems capable of maintaining stable yields and purity across multiple rare earth elements simultaneously. Very few facilities outside China have ever operated at a meaningful scale.
REalloys (NASDAQ: ALOY) is attempting to rebuild that capability in North America.
At its Euclid, Ohio platform, the company converts rare earth oxides into finished metals and magnet-grade alloys for manufacturers supplying the defense industrial base and advanced industrial sectors.
The newly demonstrated fluorination technology pushes that effort one step further upstream.
By eliminating hydrofluoric acid from the fluorination stage, REalloys’ process could remove one of the most hazardous chemical inputs historically required in rare earth metallurgy, according to the company. If scalable, it would allow the same industrial platform being expanded to rebuild Western rare earth metals capacity to operate with a materially lower environmental and safety burden.
In other words, the effort to scale rare earth metallization outside China may not only restore supply—it may also produce a cleaner version of the industry as it returns.
The Rare Earth Squeeze Is Already Underway
For years, rare earth supply looked abundant because China flooded the market.
That era is ending.
Global demand for rare earth materials is expected to multiply in the coming decades as electrification, defense modernization and advanced manufacturing expand simultaneously. Many industry forecasts project demand doubling or tripling by the 2030s and rising several-fold again by mid-century.
At the same time, China now consumes the majority of the rare earths it produces.
Roughly 60 percent of Chinese supply is absorbed domestically by electric vehicle manufacturing, wind turbines, robotics, consumer electronics, and advanced industrial production. As those industries grow, China’s surplus available for export continues to shrink.
Capital markets have already begun to reflect this shift. A small cluster of companies tied to rare earth extraction, processing, and downstream integration are increasingly being viewed as strategic rather than cyclical plays. Firms like MP Materials (NYSE: MP), Lynas Rare Earths (OTC: LYSDY), and USA Rare Earth (NASDAQ: USAR) are no longer just commodity producers—they are emerging as critical infrastructure in a supply chain that is being rebuilt under political and industrial pressure.
Which means the world is entering a very different rare earth market than the one that existed a decade ago.
Demand is rising sharply, and the buffer of surplus supply is disappearing. As that happens, the West finds itself lacking. The vulnerabilities have already emerged.
When China previously restricted rare earth exports, the shock moved through supply chains almost immediately. Industrial users—from automotive manufacturers to electronics producers—found themselves scrambling for materials that had quietly become essential to modern manufacturing.
And the exposure goes far beyond defense contractors.
Permanent magnet motors used in electric vehicles rely on rare earth elements to deliver the efficiency and performance required by next-generation EV platforms. At the same time, the rapid build-out of cloud and artificial intelligence infrastructure is driving demand for advanced cooling systems, robotics, and automation equipment that also rely on rare earth magnets.
Rare earth materials now underpin two of the fastest-growing industrial sectors on the planet: electrification and digital infrastructure.
Yet the Western world built almost no strategic buffer for them.
Now the timeline is fixed.
Beginning January 1, 2027, new U.S. defense procurement rules will prohibit Chinese-origin rare earth materials from entering the American defense supply chain—across every stage, from mining and refining to metallization and magnet production.
Every defense contractor in the country will need a qualified, non-Chinese source of supply.
This explains why the small number of companies rebuilding rare earth metals capacity outside China suddenly matters far more than it did only a few years ago.
