DYSPROSIUM (DY)

CRITICAL RISK
Overview
A heavy rare earth element used to preserve magnetic strength and operational stability in extreme heat environments. Dysprosium is essential for high-temperature NdFeB permanent magnets used in advanced aerospace propulsion, hypersonic systems, military actuators, and nuclear technologies.
Strategic importance
Dysprosium is added to NdFeB magnets to maintain performance at high temperatures — a requirement for jet engines, hypersonic systems, advanced radar actuators, and military aerospace applications. Few commercially viable substitutes exist for high-temperature magnetic systems operating under extreme stress and thermal loads.

Risk score breakdown
Supply Concentration Heavy rare earth deposits are concentrated in southern China and Myanmar, with limited meaningful production elsewhere. 19 / 20
Processing Concentration China controls roughly 90%+ of heavy REE refining and dominates high-temperature magnet supply chains. 20 / 20
Geopolitical Exposure Myanmar instability, Chinese export controls, and allied dependence on Chinese midstream processing create severe exposure. 19 / 20
Defense Criticality Essential for hypersonic systems, jet propulsion, military aerospace actuators, and high-temperature defense magnets. 19 / 20
Substitution Difficulty Few viable substitutes for dysprosium-enhanced magnets in extreme heat and stress environments at defense scale. 18 / 20

Global supply chain map
Key stats
Known reserves~2–5M tons estimated contained. Global production is limited and concentrated in China and Myanmar. China accounts for ~90%+ of refining; export controls create indirect exposure through Chinese heavy REE and magnet supply chains.

Strategic impact
Dysprosium is foundational to high-temperature permanent magnets used in advanced fighter aircraft, hypersonic systems, jet propulsion, radar actuators, and strategic energy infrastructure. A disruption in dysprosium supply chains would directly affect aerospace readiness, missile manufacturing timelines, advanced propulsion systems, and military modernization initiatives. Because dysprosium is a heavy rare earth with highly concentrated supply and limited substitutes, the strategic vulnerability is severe.
Supply chain control

China

Heavy rare earth supply and processing heavily tied to China/Myanmar flows.

Risk indicators
  • Myanmar civil war has destabilized the only significant non-China source
  • Routed almost entirely through Chinese refineries with no bypass
  • Western alternatives are a decade away from meaningful scale
Risk & challenge analysis
Dysprosium supply chains are heavily dependent on heavy rare earth deposits in southern China and Myanmar, with nearly all downstream refining controlled by Chinese processors. Myanmar's ongoing civil conflict has introduced instability into one of the only meaningful non-China supply sources. Western efforts to establish alternative heavy rare earth refining and magnet manufacturing ecosystems remain years away from industrial-scale capability.
Strategic insight
Hypersonic missile programs, advanced fighter engines, and high-temperature aerospace systems are directly exposed to dysprosium disruption risk. Myanmar instability may reduce available heavy REE supply before allied diversification initiatives become operational, increasing near-term strategic vulnerability.
