The primary end-uses of Dysprosium span multiple sectors, each contributing to its classification as a critical material. The following applications represent the most significant sources of global demand:

• Neodymium-iron-boron permanent magnets — Dysprosium plays a vital role in neodymium-iron-boron permanent magnets, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Nuclear reactor control rods — Dysprosium plays a vital role in nuclear reactor control rods, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Laser materials — Dysprosium plays a vital role in laser materials, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Data storage devices — Dysprosium plays a vital role in data storage devices, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.

Sector Breakdown

The largest consuming sector for Dysprosium is neodymium-iron-boron permanent magnets, which accounts for a substantial share of global demand. The second most significant application is nuclear reactor control rods, which has shown strong growth in recent years driven by technology adoption and regulatory requirements. Emerging applications across clean energy, defense, and advanced manufacturing are expected to expand the demand profile for Dysprosium in the coming decade.

Demand Outlook

With a criticality level of high and a supply risk rating of high, the demand trajectory for Dysprosium is closely monitored by governments and industry analysts. Its inclusion on the USGS critical minerals list underscores the strategic importance of securing stable supply for domestic industries. The European Union has similarly recognized its importance through inclusion on the EU Critical Raw Materials list. Growing demand from electrification, digitalization, and defense modernization programs is expected to place additional pressure on existing supply chains.
