· JVASP-111323· Li2Al

Li2Al is an intermetallic compound combining lithium and aluminum, belonging to the lightweight metal intermetallic family. This material is primarily of research and development interest rather than established industrial production, as it exhibits extremely low density while maintaining metallic bonding characteristics—making it potentially valuable for aerospace and weight-critical applications. The compound's actual commercialization remains limited; interest centers on lithium-aluminum systems for next-generation lightweight structural composites and advanced battery materials, though challenges in synthesis, stability, and processing have prevented widespread engineering adoption.

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.
