· JVASP-151599· Hf3AlN

Hf3AlN is a ternary metal nitride compound combining hafnium, aluminum, and nitrogen, belonging to the family of refractory metal nitrides. This material is primarily of research and developmental interest for ultra-high-temperature applications where exceptional hardness, thermal stability, and oxidation resistance are required; it represents an emerging candidate for next-generation cutting tools, wear-resistant coatings, and aerospace thermal-protection systems where conventional superalloys reach their limits.

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.
