· JVASP-89903· HfAlNi

HfAlNi is a ternary intermetallic compound combining hafnium, aluminum, and nickel, belonging to the refractory metal alloy family. This material is primarily investigated in research contexts for high-temperature structural applications where exceptional thermal stability and oxidation resistance are required. The hafnium-aluminum-nickel system is of particular interest for aerospace and power generation components that operate in extreme thermal environments where conventional superalloys reach their performance 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.
