FeB2

FeB2 is an iron diboride ceramic compound that belongs to the family of transition metal borides, characterized by a hexagonal crystal structure. It is primarily of research and industrial interest for applications requiring extreme hardness and thermal stability, particularly in cutting tools, wear-resistant coatings, and high-temperature structural components. While less commonly deployed than conventional cemented carbides, iron boride offers potential advantages in abrasive machining environments and as a reinforcement phase in composite materials where cost-effectiveness and chemical inertness are valued over maximum hardness.
