· Mn2B

Mn₂B is an intermetallic compound composed of manganese and boron, belonging to the family of metal borides that exhibit high hardness and stiffness. This material is primarily of research and developmental interest rather than established commercial production, with potential applications in wear-resistant coatings, hard tool materials, and high-temperature structural applications where boron-containing intermetallics show promise. Mn₂B is notable within the boride family for its combination of mechanical rigidity and density characteristics, making it a candidate material for specialized engineering environments, though industrial adoption remains limited compared to more established ceramic or refractory alternatives.
