· MnB2

MnB2 is a transition metal boride compound combining manganese and boron in a 1:2 stoichiometric ratio. This material belongs to the family of refractory metal borides, which are typically studied for extreme-temperature and wear-resistant applications. While primarily a research material rather than a widely commercialized engineering grade, metal borides like MnB2 are investigated for high-hardness coatings, cutting tool materials, and environments where traditional alloys degrade.
