· Y2Al

Y2Al is an intermetallic compound combining yttrium and aluminum, belonging to the rare-earth metal family of advanced materials. This material exhibits characteristics typical of yttrium-aluminum systems, which are investigated for high-temperature applications and structural uses where lightweight properties and thermal stability are desired. Y2Al and related yttrium-aluminum phases are primarily of research and specialized industrial interest rather than commodity materials, with potential applications in aerospace, thermal barrier coatings, and advanced structural composites where rare-earth intermetallics can offer advantages in specific temperature or loading regimes.

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.
