· HfAlNi2

HfAlNi2 is a ternary intermetallic compound combining hafnium, aluminum, and nickel, representing a high-performance metallic system studied for structural and functional applications requiring elevated-temperature stability and mechanical resilience. This material belongs to the family of refractory metal intermetallics and is primarily investigated in research and development contexts for aerospace, power generation, and high-temperature engineering environments where conventional superalloys reach their performance limits. The hafnium-aluminum-nickel system is valued for its potential to combine the oxidation resistance of aluminum-bearing phases with the structural integrity of nickel-base matrices, along with hafnium's contribution to refractory strength and creep resistance.

Export Control

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.
