MnB
metal· MnB
MnB is a manganese boride intermetallic compound that forms a hard ceramic-like phase used primarily in wear-resistant and high-temperature applications. It appears in cutting tool coatings, wear-resistant composites, and specialized alloy systems where hardness and thermal stability are required. Engineers select manganese boride when superior hardness and chemical resistance are needed in extreme environments, though its brittleness and processing complexity make it suitable mainly for coatings or reinforcement phases rather than bulk structural components.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
