PrFe2

metal

· JVASP-14522· PrFe2

PrFe2 is an intermetallic compound composed of praseodymium and iron, belonging to the rare-earth iron intermetallic family. This material is primarily investigated for permanent magnet and magnetostrictive applications, leveraging rare-earth iron compounds' strong magnetic coupling. While not as widely deployed as established rare-earth magnets (Nd-Fe-B), PrFe2-based systems are of interest in research and specialty applications where praseodymium's magnetic properties and thermal stability offer advantages over other rare-earth options, or where cost considerations drive alternative rare-earth selections.
