· JVASP-15269· AlFe2B2

AlFe2B2 is an intermetallic compound combining aluminum, iron, and boron, belonging to the family of hard ceramic-like metal borides. This material is primarily of research and development interest rather than a mainstream industrial alloy, studied for its potential in high-hardness applications where conventional alloys fall short. It represents the growing class of boride intermetallics that could serve specialized roles in wear resistance and high-temperature structural applications, though industrial adoption remains limited compared to established carbide or nitride alternatives.
