NiN
metal· NiN
Nickel nitride (NiN) is a ceramic intermetallic compound combining nickel with nitrogen, forming a hard, refractory material in the transition metal nitride family. It is primarily investigated as a coating material and structural reinforcement phase, particularly valued in wear-resistant and high-temperature applications where its hardness and chemical stability provide advantages over conventional metallic alloys. Industrial adoption remains limited but growing in specialized sectors such as cutting tools, tribological coatings, and composite reinforcement, where NiN serves as an alternative to traditional carbides or nitrides when nickel-based binders or compatibility with nickel superalloys is advantageous.

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.
