Dysprosium (Dy) is a rare-earth lanthanide metal known for its exceptional magnetic properties and high melting point, making it valuable in specialized high-performance applications. It is primarily used in permanent magnets (particularly neodymium-dysprosium alloys), nuclear control rods, and high-temperature structural applications where magnetic strength retention and thermal stability are critical. Engineers select dysprosium-containing materials when standard ferromagnetic alloys cannot meet performance requirements at elevated temperatures or when enhanced coercivity is needed to prevent demagnetization in demanding environments.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
