· JVASP-57693· Ba3Al5

Ba3Al5 is an intermetallic compound in the barium-aluminum system, representing a rare-earth-free metallic phase with potential applications in lightweight structural materials and functional alloys. This material belongs to the family of binary intermetallics and is primarily of research interest rather than established industrial production; its development is driven by the search for alternatives to rare-earth-containing alloys and the potential to exploit barium's unique combination of low density and high atomic mass for specialized engineering applications.

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.
