Rare Earth Magnet Powder: Supply, Types & Outlook

A post-tax NPV of US$409m at current prices signals that western rare earth magnet powder production has crossed from strategic aspiration into commercial reality. HyProMag’s Texas Hub — a 1,552 metric tonne per annum recycled NdFeB facility — carries an all-in sustaining cost of US$22.3/kg against a weighted average market price of US$56.8/kg, with first revenue targeted for Q1 2027.

What Is Rare Earth Magnet Powder?

Rare earth magnet powder is the intermediate material from which permanent magnets are pressed, sintered, or bonded. The dominant type is NdFeB powder — an alloy of neodymium, iron, and boron — which underpins the strongest permanent magnets commercially available. The secondary type is SmCo (Samarium Cobalt) powder, which operates at temperatures up to 300°C and is preferred in aerospace and defence applications where thermal stability outweighs the higher unit cost.

NdFeB powder divides into two structural forms. Isotropic powder is produced by rapid gas atomisation or melt-spinning; its randomly oriented grains deliver moderate magnetic performance and are used in bonded magnets for small motors and sensors. Anisotropic powder is jet-milled to finer particle sizes and aligned in an external magnetic field during pressing — this produces sintered magnets with maximum energy density, and is the form used in EV drivetrains, wind turbine generators, and defence systems.

The key rare earth inputs split by function. Neodymium and praseodymium — light rare earth elements — provide the core magnetic force. Dysprosium and terbium — heavy rare earth elements — are added in small percentages to maintain coercivity at elevated operating temperatures, critical for EV motors and wind generator applications. Raw NdFeB powder in fine particle sizes is pyrophoric and must be handled under vacuum or inert gas (argon) throughout the production process.

How Rare Earth Magnet Powder Is Produced

The primary production route runs from mining through chemical separation to alloy production and powder milling. Rare earth concentrates are separated into individual oxides, reduced to metals, alloyed in precise ratios, and then processed into powder via strip casting and jet milling. China controls the dominant share of primary NdFeB powder production, from feedstock processing through to finished powder — a structural position built over three decades of investment in separation and alloying capacity. Current market share data should be verified against a live source before citing a specific figure.

The western alternative is short-loop recycling via Hydrogen Processing of Magnet Scrap (HPMS) — a patented technology developed at the University of Birmingham by Professor Rex Harris and Professor Allan Walton, and now commercialised through HyProMag. The HPMS process exposes end-of-life NdFeB magnets embedded in scrap equipment to hydrogen gas, which causes the alloy to decrepitate — disintegrating into powder without the need for chemical dissolution. A single HPMS batch can recover over 400 kg of rare earth alloy. The short-loop route requires an estimated 88% less energy than the primary mining-to-magnet production pathway, according to HyProMag’s lifecycle analysis.

A parallel long-loop recycling route handles HPMS powder not suitable for direct reuse and magnet swarf from grinding and finishing operations. The long-loop process applies chemical separation to produce discrete rare earth carbonates or oxides — including separated neodymium-praseodymium and dysprosium-terbium fractions — which re-enter the supply chain as refined intermediates. Both routes are underpinned by the same patented HPMS technology. Neodymium pricing data from Shanghai Metals Market provides the benchmark against which recycled NdPr output is valued.

Western Rare Earth Magnet Powder Supply — Three Facilities

HyProMag is 100% owned by Maginito Limited, which is a 79.4% subsidiary of Mkango Resources Ltd (TSXV/AIM: MKA). Three commercial facilities are at different stages of development across the UK, Germany, and the United States.

The UK facility at Tyseley Energy Park, Birmingham, achieved first production of recycled NdFeB alloy in June 2025 — the first commercial rare earth sintered magnet production in the UK in 25 years. Funded by a £4.3m UKRI Driving the Electric Revolution Challenge grant, the facility operates at a minimum 100 tonnes per annum NdFeB on a single shift, scalable to 300+ tpa on multiple shifts. The official opening took place in January 2026, presided over by the UK Minister for Industry. The facility sits within the policy framework of the UK Critical Minerals Strategy (November 2025), which targets 10% of annual critical mineral demand from domestic sources by 2035 and 20% from recycling by 2035.

The Germany facility — HyProMag GmbH, located in Baden-Württemberg near Pforzheim — is 80% owned by HyProMag and 20% by Professor Carlo Burkhardt of Pforzheim University. Burkhardt coordinates the €14m SusMagPro and €13m REEsilience EU-funded recycling programmes, involving 40+ partners across the supply chain. Initial capacity is a minimum 100 tpa NdFeB. Site development is underway with HPMS reactor and jet mill installed; first production was targeted for Q1 2026.

The Texas Hub — HyProMag USA LLC — is the largest and most commercially advanced of the three. It operates as a 50/50 joint venture between CoTec Holdings and Maginito Limited, with HyProMag sublicensing the HPMS technology to the US entity. The hub-and-spoke model centres on a Texas manufacturing hub with pre-processing spokes at Intelligent Lifecycle Solutions (ILS) facilities in South Carolina and Nevada. Detailed engineering has been led by PegasusTSI Inc. (US) and BBA USA Inc. (Canada), with a Class 2 AACE capital cost estimate completed in December 2025. Total initial capital cost is US$142m (8.2% contingency, one-year build). Combined capacity is 941 metric tpa recycled sintered NdFeB magnets plus 611 metric tpa NdFeB co-products, totalling 1,552 metric tpa. At current prices, post-tax NPV is US$409m with an IRR of 27.6% and a payback period of 3.1 years. At forecast prices, NPV rises to US$780m, IRR to 38.7%, and payback shortens to 2.2 years. The facility is expected to create 90–100 skilled manufacturing jobs and carries a 40-year operating life.

Neo Performance Materials operates separately as a processor of rare earth alloys and bonded magnet powders, with facilities in Estonia and Thailand, representing a distinct commercial pathway for non-Chinese NdFeB intermediate supply outside the recycling route.

Rare Earth Magnet Powder and Defence Supply Chains

The Texas Hub is designed from the outset to meet DFARS 252.225-7052 — the US Department of Defense procurement rule requiring domestically produced specialty metals in defence articles. This positions HyProMag USA as the first US source of DFARS-compliant recycled NdFeB sintered magnet material, serving defence, aerospace, automotive, medical, hyperscale data centres, and robotics applications. The January 2027 full compliance deadline for contractors under DFARS 252.225-7052 creates a defined procurement window for domestic suppliers.

The Minerals Security Partnership (MSP) recognised NdFeB magnet material as a priority technology in October 2023, aligning allied-nation governments around supply chain development for this specific material class. The US, UK, EU, Australia, Canada, Japan, and South Korea are all MSP signatories — providing a policy demand signal that runs parallel to commercial offtake negotiations. For investors, a strategic review is underway for a potential separate US listing of HyProMag USA, expected late 2026 or early 2027, which would provide dedicated capital markets access to the Texas facility’s economics.

The top rare earth magnet manufacturers globally remain predominantly Chinese, which is why DFARS-compliant western production carries a premium in defence procurement contexts beyond its commercial economics alone.

Rare Earth Magnet Powder Outlook

HyProMag USA’s independent ISO-compliant lifecycle study puts the carbon footprint of recycled sintered NdFeB block at 2.35 kg CO2-eq per kg — a figure that is likely to become a procurement differentiator as defence and automotive OEMs formalise Scope 3 reporting requirements. Combined with the 88% energy saving over the primary production route, the recycled pathway is positioned as both a cost-competitive and lower-carbon source of rare earth magnet powder.

The scale-up trajectory runs from 100 tpa in Birmingham to 100 tpa in Baden-Württemberg to 1,552 tpa in Texas — a combined western recycling capacity of approximately 1,752 tpa once all three facilities reach nameplate output. The long-loop pilot at Tyseley, funded 70% by UKRI under the SCREAM project with partners including GKN Automotive, Jaguar Land Rover, Bowers & Wilkins, and European Metal Recycling, targets first batches of separated Dy/Tb carbonates and oxides — closing the loop on the heavy rare earth inputs that currently remain import-dependent regardless of short-loop NdFeB recycling. Scoping studies for scale-up of the long-loop route — whether standalone, joint venture, or other structure — are underway.

The western rare earth magnet supply chain shift depends on facilities like these moving from pilot to production on schedule. The Notice to Proceed for HyProMag USA, following completion of Detailed Engineering, is the next material milestone to watch.
