HoAl2
metal· JVASP-14690· HoAl2
HoAl2 is an intermetallic compound combining holmium (a rare-earth element) with aluminum, forming a metallic phase used primarily in research and specialized high-performance applications. This material belongs to the rare-earth intermetallic family, which exhibits unique combinations of strength and thermal properties that make it relevant for advanced aerospace and high-temperature engineering. Engineers typically consider HoAl2 for extreme environments where conventional alloys reach their thermal or mechanical limits, though commercial adoption remains limited compared to standard aluminum alloys or nickel-based superalloys.

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.
