Dysprosium’s Unique Role in High-Performance Magnetic Storage
Dysprosium (Dy) has solidified its status as a strategic element in the evolution of high-performance magnetic storage technologies, particularly as global demand for data storage capacity accelerates into 2025. The unique magnetic and thermal properties of dysprosium make it indispensable in the manufacture of high-coercivity neodymium-iron-boron (NdFeB) magnets, which are foundational to hard disk drives (HDDs) and emerging storage technologies. By adding dysprosium to NdFeB magnets, manufacturers substantially increase their resistance to demagnetization, especially at the elevated temperatures experienced in data centers and enterprise storage environments.
Leading magnetic materials suppliers, such as Hitachi Metals, Ltd. and TDK Corporation, have continued to refine and scale the production of dysprosium-enhanced NdFeB magnets. In 2025, these advancements are enabling higher areal densities in HDDs, with disk platters capable of storing several terabytes each, pushing toward the industry’s multi-petabyte objectives for cloud-scale storage (Seagate Technology). As a result, dysprosium’s supply chain remains a focal point for both manufacturers and policymakers, with efforts to ensure stable sourcing and recycling initiatives.
In parallel, research into heat-assisted magnetic recording (HAMR) and other next-generation storage methods is intensifying. HAMR drives, now reaching commercial deployment by companies like Seagate Technology, leverage dysprosium-based magnets for their robust high-temperature performance, which is vital for the precise and localized heating required by these technologies. The reliability and efficiency of HAMR depend on dysprosium’s ability to maintain magnetization under repeated thermal cycling, a challenge that alternative rare earth elements have not matched.
Looking ahead to the next few years, the outlook for dysprosium-based magnetic storage technologies remains strong. Leading manufacturers are investing in research to reduce the proportion of dysprosium required without sacrificing performance, aiming to alleviate supply risks and costs (TDK Corporation).

Supply Chain Risks: Dysprosium Sourcing, Geopolitics, and Sustainability
Dysprosium is a critical rare earth element widely used in the fabrication of advanced magnetic storage technologies, particularly for high-performance hard disk drives and emerging next-generation memory devices. The reliability and scalability of dysprosium-based magnetic storage technologies are intricately tied to the integrity of their supply chains, which face significant pressures in 2025 and the coming years due to sourcing challenges, geopolitical tensions, and sustainability concerns.
Currently, dysprosium is predominantly produced as a byproduct of rare earth mining, with Aluminum Corporation of China Limited (CHINALCO) and China Molybdenum Co., Ltd. among the major suppliers, reflecting China’s ongoing dominance of the global rare earths market. According to recent industry statements, China supplies over 60% of global dysprosium, a concentration that leaves downstream manufacturers vulnerable to export controls, trade disputes, and domestic policy shifts in China.
In response to these risks, companies such as Lynas Rare Earths have accelerated efforts to develop alternative mining and processing infrastructure outside of China, notably in Australia and Malaysia. In 2025, Lynas has expanded its Mount Weld operations and increased downstream processing capacity, aiming to supply dysprosium for strategic applications, including magnetic storage, to North American, European, and Japanese manufacturers. Nevertheless, the ramp-up is gradual due to technical and regulatory hurdles, and non-Chinese supply remains limited.
Geopolitical tensions, particularly between the US, EU, and China, continue to cast uncertainty on the dysprosium supply chain. The US Department of Energy has underscored the vulnerability of critical magnet supply chains and is supporting efforts to localize rare earth separation and magnet manufacturing capacity in the United States. Companies like MP Materials have announced investments in integrated rare earth supply chains, including plans to produce separated dysprosium oxide for domestic industries. However, most of these initiatives are not expected to reach significant scale before 2026–2027.
Sustainability is increasingly prioritized by both regulators and end-users of dysprosium-based storage technologies. Leading rare earth producers are investing in environmentally responsible extraction, such as water recycling and tailings management. In 2025, Lynas Rare Earths has implemented enhanced waste management systems at its Malaysian processing plant to comply with new environmental standards. Additionally, the growing emphasis on recycling end-of-life magnets and e-waste is prompting companies like Umicore to expand rare earth recovery operations, offering a partial buffer against primary supply risks.
Looking ahead, the outlook for dysprosium sourcing in support of magnetic storage remains constrained by supply concentration and geopolitical risks, despite ongoing diversification and recycling initiatives. The ability of manufacturers to secure stable, sustainable dysprosium supplies will be a key determinant of innovation and competitiveness in advanced magnetic storage technologies through the rest of the decade.
