Nb4AlN3
metal· JVASP-140246· Nb4AlN3
Nb4AlN3 is a ternary metal nitride compound combining niobium, aluminum, and nitrogen, belonging to the family of refractory transition metal nitrides. This material is primarily of research interest rather than an established commercial product, developed for high-temperature structural applications where conventional alloys lose strength; its appeal lies in potential hardness, thermal stability, and oxidation resistance typical of nitride ceramics, making it a candidate for extreme environment components where weight and thermal performance trade against brittleness common to ceramic materials.

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.
