· JVASP-15158· ErFe2B2

ErFe2B2 is an intermetallic compound combining erbium, iron, and boron, belonging to the rare-earth metal boride family. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-performance magnetic, structural, or thermal applications where rare-earth strengthening and boride stability are advantageous. Engineers would consider this compound when exploring advanced alloy systems for extreme environments or specialized functional properties, though availability and processing maturity remain limited compared to conventional commercial alternatives.
