· JVASP-142489· MnNi5N4

MnNi5N4 is a manganese-nickel nitride compound belonging to the metal nitride family, which combines metallic and ceramic-like characteristics. This material is primarily of research and development interest for applications requiring high hardness and wear resistance, with potential use in tool coatings, wear-resistant surfaces, and high-temperature applications where nitride stability becomes advantageous. The manganese-nickel combination offers a balance between hardness and toughness that distinguishes it from single-element nitride systems.

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.
