Y3(Fe31B7)2

Y3(Fe31B7)2 is an iron-based rare-earth intermetallic compound containing yttrium, iron, and boron. This material belongs to the family of rare-earth permanent magnets and hard magnetic materials, though it represents a research-phase composition rather than an established commercial alloy. The yttrium-iron-boron system is studied for potential applications in high-temperature magnetic devices and permanent magnet applications where the inclusion of rare-earth elements enhances magnetic performance; however, engineers should verify current availability and maturity relative to established alternatives like Nd₂Fe₁₄B or samarium-cobalt magnets.
