Dysprosium
Rare Earth
Last updated: January 2026Overview
A heavy rare earth element essential for high-temperature permanent magnets. Dysprosium additions to NdFeB magnets prevent demagnetization at elevated temperatures, critical for EV motors and wind turbines.
Strategic Relevance
Irreplaceable for high-performance magnets operating above 150°C. Supply is extremely concentrated with limited substitutes.
