· JVASP-106249· Hf3Al

Hf3Al is an intermetallic compound in the hafnium-aluminum system, representing a high-melting-point metallic material combining hafnium's refractory properties with aluminum's lightweight character. This material is primarily of research and development interest for ultra-high-temperature applications where exceptional thermal stability and oxidation resistance are required, particularly in aerospace and advanced energy systems 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.
