· JVASP-110956· YUAl4

YUAl4 is an intermetallic compound composed of yttrium and aluminum, belonging to the rare-earth aluminum family of metallic materials. This material is primarily of research and specialized industrial interest, explored for applications requiring the combination of light weight with high-temperature stability and unique electronic or magnetic properties that intermetallics can provide. Its adoption remains limited compared to conventional aluminum alloys, but it represents the broader potential of rare-earth intermetallics in advanced aerospace, thermal management, and functional material applications where conventional alloys 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.
