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.
