PMT Critical Metals - Pioneering Rare Earth Manufacturing in the U.S.

In a world increasingly dependent on advanced technologies, we are leading the charge to bring vital materials back home—where they belong.

Magnets Are Essential

Magnets are used everywhere. Every missile, aircraft, ship, cell phone, computer, car, speaker, wind turbine, diagnostic equipment, and hundreds of other things that you come across have magnets in them. And they play a critical role in Electrification – from defense to renewable energy to cars to pretty much every industrial equipment and process. But unfortunately, we do not make any magnets in the U.S.

Securing a North American Magnet Supply Chain

Our mission along with our parent company, REalloys Inc., is to secure a domestic, reliable, sustainable, and independent supply of magnets for the U.S. economy. By leveraging cutting-edge processing technologies and environmentally responsible practices, we are reshaping industry to reduce reliance on foreign sources and ensure long-term national security and economic stability.

Innovating High-Performance Magnet Technology

We are enabling the next generation of higher efficiency, higher power density and lower cost motors and generators with permanent magnets that are manufactured domestically in the U.S., meeting increased demand for electrification. Our ability to computationally identify advanced materials, create proprietary formulations, develop novel processing routes, topology optimization, and its know-how to control microstructures (to resolve issues related to grain boundary engineering and alignment) enables us to develop the highest value magnets.

Powering a Resilient Future for North America

We are building the foundation for a resilient, independent, and sustainable future. Whether you are an investor, industry partner, or government entity, we invite you to join us in reshaping the magnet landscape.

NdFeB Magnet Applications

Together with our parent company, REalloys Inc., PMT Critical Metals is on a mission to establish a sustainable, independent, and secure source of U.S.-made magnets. Through advanced processing technology and responsible practices, we’re reshaping the magnet manufacturing industry for a resilient future.

Aerospace & Defense

In aerospace and military applications, permanent magnets are indispensable. Missiles rely on magnet-based motors to control their flight surfaces with precision. In aircraft, generators use permanent magnets to supply reliable electrical power to essential systems. The high performance and durability of these magnets make them ideal for the demanding conditions of defense and aerospace operations.

Automotive

Permanent magnets are a critical component in modern vehicles, particularly electric vehicles (EVs). They are used in EV motors to enhance power efficiency and overall performance, enabling longer ranges and better energy management. Additionally, magnets are found in sensors and actuators that control various automotive systems, improving safety, responsiveness, and automation across vehicle platforms.

Motors & Generators

From industrial machinery to everyday appliances, permanent magnets are vital in various electric motors and generators. Their high efficiency and reliability make them the preferred choice in many applications. This includes electric motors in EVs, factory equipment, and consumer devices, where they help convert electrical energy into motion. Similarly, they play a key role in wind turbines, where they convert mechanical energy from wind into usable electricity.

Wind Turbines

In the renewable energy sector, wind turbines rely heavily on permanent magnets. These magnets are used in turbine generators to convert kinetic energy from wind into electrical energy. Their efficiency, durability, and ability to function without requiring external excitation systems make them ideal for onshore and offshore wind power generation, playing a key role in advancing clean energy infrastructure.

Consumer Electronics

Magnets are found throughout consumer electronics, powering devices we use daily. In speakers and microphones, they provide strong and consistent magnetic fields to deliver high-quality sound. Hard disk drives use permanent magnets in their motors to enable high-speed spinning and efficient data access, supporting everything from personal computing to enterprise-level data centers.

Medical Devices

In the medical field, magnets enable the performance and functionality of advanced diagnostic and treatment tools. MRI machines rely on strong, stable magnetic fields to produce detailed internal images of the human body. Magnets are also present in dental equipment, such as high-speed handpieces and dental implants, enhancing precision and reliability in patient care.

Industrial Applications

Magnets are essential in various industrial processes. Magnetic separators are used in mining, recycling, and manufacturing to remove ferrous contaminants from materials, ensuring product purity and protecting machinery. In lifting and holding devices, permanent magnets provide a secure, maintenance-free solution for manipulating heavy metal parts on the factory floor or construction site.

Power Generation

In the energy sector, magnets are key components in generators and turbines, including those in fossil-fuel and renewable power plants. Their ability to perform under high temperatures and extreme conditions ensures consistent power output and system reliability.

Oil & Gas Industry

Drilling and exploration equipment in the oil and gas industry often operate in harsh environments. Permanent magnets used in downhole tools must maintain their magnetic properties at extreme depths and high temperatures, ensuring performance and safety during operations.

NdFeB Magnet Manufacturing

In addition to manufacturing NdFeB magnetic materials, PMT Critical Metals also manufactures finished magnets utilizing a variety of manufacturing processes. We have significant internal and external manufacturing capacity to meet large production volumes for sintered, bonded, machined, injection molded and cast magnets.

Sintered Magnets

Compressed magnetic powder is heated just below its melting point to produce high-strength, durable magnets. Ideal for electric motors, generators, and MRI machines.

Bonded Magnets

Magnetic powder mixed with a binder and molded into complex shapes. Lightweight and versatile, perfect for sensors, medical devices, and automotive components.

Machined Magnets

Precision-shaped from sintered or cast materials for exact dimensions. Common in aerospace and industrial systems requiring tight tolerances.

Injection Molded Magnets

Formed by injecting magnetic material into molds, allowing intricate designs with moderate strength. Used in electronics and small motor applications.

Cast Magnets

Molten material poured into molds, producing large, mechanically strong magnets. Suited for industrial machinery and heavy-duty motors.

Rare Earth Elements Processing

At PMT Critical Metals, we’ve built state-of-the-art infrastructure dedicated to the secondary processing of rare earth oxides (REOs)—a crucial step that transforms purified oxides into high-performance metals, alloys, and compounds used in magnets, batteries, electronics, and catalysts.

Conversion Process

To prepare REOs for reduction, they are first converted into more reactive forms:

Fluorination: REOs are reacted with hydrofluoric acid to form rare earth fluorides (REF₃), ideal for molten salt electrolysis.

Chlorination: REOs are exposed to chlorine gas and a reducing agent to produce rare earth chlorides (RECl₃), commonly used in both electrolysis and direct reduction methods.

Reduction to Metals

Once converted, the materials undergo reduction to extract the pure metal:

Metallothermic Reduction: Calcium or aluminum is used as a reducing agent in a vacuum or inert environment to produce high-purity rare earth metals.

Molten Salt Electrolysis: RE chlorides or fluorides are dissolved in molten salts at high temperatures, with pure metals collected at the cathode—achieving purities over 99.9%.

Refining & Purification

To meet the stringent demands of advanced applications, metals undergo additional refinement:

Vacuum Distillation: Removes impurities like calcium and magnesium, especially effective for heavy rare earths such as dysprosium and terbium.

Zone Refining: A controlled molten zone passes through the ingot to separate impurities.

Electrorefining: Dissolves impure metal in an electrolyte, plating high-purity metal at the cathode.
