AlB₂ is an aluminum diboride intermetallic compound belonging to the hexagonal metal boride family, characterized by a layered crystal structure that imparts high stiffness and relatively low density. This material is primarily investigated in research and advanced aerospace contexts for lightweight structural applications and composite reinforcement, where its combination of rigidity and low weight offers potential advantages over conventional aluminum alloys, though industrial adoption remains limited and production methods continue to be refined.
