· JVASP-19590· MnB4

MnB4 is a manganese boride ceramic compound that belongs to the refractory boride family, known for extreme hardness and high-temperature stability. While primarily investigated in research and materials development contexts rather than established industrial production, manganese borides are of interest for applications requiring wear resistance and thermal durability. The material represents a potential alternative to conventional hard-facing and refractory systems, though its engineering adoption remains limited compared to established borides like tungsten boride or titanium boride.

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.
