NdPr (Neodymium-Praseodymium): The “muscle” of the green economy. Essential for the high-strength permanent magnets (NdFeB) that power 85% of electric vehicle motors and offshore wind turbines. DyTb (Dysprosium-Terbium): The “heat shield.” These scarce heavy rare earths are added to magnets to ensure performance at high temperatures, critical for defence systems and heavy-duty drivetrains.
Market Driver: EV demand alone is forecast to consume ~50% of global magnet supply by 2040.
Supply Risk: With China controlling ~90% of refining, IMC Rare Earths is developing a diversified, secure supply chain.
These elements are the non-negotiable building blocks of modern security and sustainability.
From the drivetrains of electric vehicles to precision-guided defence systems and advanced electronics, rare earths are the silent engine behind the global energy transition.
Magnet rare earths—specifically the basket of NdPr (Neodymium-Praseodymium) and DyTb (Dysprosium-Terbium)—dominate the market's economics.
While they make up a fraction of mined volume, they generate over 90% of the total market value, making them the priority focus for high-margin production.
Heavy rare earths (DyTb) command a massive price premium due to severe global supply constraints.
As critical additives for high-temperature performance, Terbium (Tb) trades at ~14x and Dysprosium (Dy) at ~4x the price of standard NdPr, offering significant upside leverage for producers with heavy-enriched deposits.
Rare earth elements (REEs) form the backbone of the technologies reshaping energy, mobility, and communication. Among them, magnet rare earths — neodymium (Nd), praseodymium (Pr), dysprosium (Dy), and terbium (Tb) — are essential for producing NdFeB permanent magnets, used in electric vehicles, wind turbines, robotics, and smart devices. Their unique properties enable compact, high-efficiency systems critical to clean energy and advanced manufacturing.
REEs are predominantly mined in China, which also dominates global refining capacity. However, increasing demand and geopolitical tensions have spurred investment in alternative mining jurisdictions, including Australia, the United States, Brazil, and Africa, alongside efforts to advance magnet recycling and reduce dependency on heavy rare earths like Dy and Tb.
As the world transitions to low-carbon technologies and electrified infrastructure, the role of REEs — especially magnet materials — has become strategically important. Their reliable supply underpins progress across clean energy, defence, mobility, and digital systems, making rare earth elements some of the most valuable inputs in the modern economy.
The four critical elements are Neodymium (Nd), Praseodymium (Pr), Dysprosium (Dy), and Terbium (Tb). Together, they form the "magnet rare earth basket," which accounts for the vast majority of the rare earth market's total value by revenue.
They are classified as critical because they are economically essential (vital for energy, defence, and tech) yet face a high risk of supply disruption. Governments worldwide, including the US and EU, prioritize securing domestic sources of NdPr and DyTb to protect national security and economic stability.
Rare earth elements are used in electric vehicle motors, wind turbine generators, consumer electronics, medical imaging systems, and defence technologies. Their magnetic, conductive, and luminescent properties make them essential for high-performance and energy-efficient devices.
NdPr (Neodymium-Praseodymium) is the primary feedstock for Neodymium Iron Boron (NdFeB) magnets, the strongest permanent magnets commercially available. It is often called the "muscle" of the green economy because it drives the motors in 85% of electric vehicles and most offshore wind turbines.
DyTb refers to the heavy rare earth elements Dysprosium (Dy) and Terbium (Tb). They act as a "heat shield" for permanent magnets, allowing them to operate at high temperatures without losing magnetism. This makes DyTb critical for defence systems, aerospace, and high-performance EV drivetrains. Due to their scarcity, they trade at a significant price premium over light rare earths.
While rare earth deposits exist globally, China currently controls ~60% of mining and ~90% of refining capacity. This concentration creates supply chain risks for Western economies. New projects in Brazil, Australia, and Africa are being developed to create a diversified, secure supply chain for critical industries.
Alternatives like ferrite magnets and iron-nitride compounds exist but offer lower performance than rare earth-based magnets. Research is ongoing into low-Dy or Dy-free magnet technologies, but NdFeB magnets remain the standard for efficiency, strength, and compact design.
Rare earth elements are essential to modern life — from smartphones and EVs to renewable energy systems and defence technologies. Yet not all rare earths offer the same strategic value.

Used to create high-strength permanent magnets, these elements — especially Nd, Pr, Dy, and Tb — are vital for EV motors, wind turbines, and advanced motion systems.
Critical for thermal stability and magnetic durability, heavy rare earths like dysprosium and terbium enhance performance in aerospace, defence, and extreme-environment technologies.
With roles in catalysts, batteries, and phosphors, light rare earths power everything from hybrid vehicles to clean fuel production — forming the foundation of mass-scale modern tech.
