· JVASP-110517· YbYAl4

YbYAl4 is an intermetallic compound composed of ytterbium, yttrium, and aluminum, belonging to the rare-earth metal family. This material is primarily of research interest rather than established in high-volume production, with potential applications in advanced thermal management, electronic device substrates, and specialized high-temperature applications where rare-earth intermetallics offer unique combinations of thermal and electrical properties. The ytterbium-yttrium-aluminum system is studied for its potential in cryogenic applications and as an alternative material for specialty aerospace or nuclear contexts where conventional metals reach 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.
