· JVASP-154414· Y5Al3

Y5Al3 is an intermetallic compound in the yttrium-aluminum system, combining rare-earth yttrium with aluminum to form a brittle metallic phase. This material is primarily of research and academic interest rather than established in large-scale commercial production, explored for potential applications in high-temperature structural materials and composite reinforcement where its intermetallic nature offers hardness and thermal stability. Engineers would consider Y5Al3 in advanced aerospace or materials science contexts where novel intermetallic phases are being evaluated for elevated-temperature performance or as reinforcement phases, though practical engineering adoption remains limited compared to conventional aluminum alloys or established intermetallics like TiAl.

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.
