· Al2Li3

Al2Li3 is an intermetallic compound in the aluminum-lithium system, representing a stoichiometric phase rather than a conventional wrought or cast alloy. This material exists primarily in research and materials science contexts as a model compound for understanding phase stability and crystal structure in lightweight Al-Li systems; industrial aluminum-lithium alloys (such as 2090, 2091, and 3rd-generation variants) achieve superior strength-to-weight ratios through controlled precipitation of related phases rather than bulk Al2Li3. Engineers would encounter this compound mainly in phase diagram studies, computational materials research, or specialized applications where the unique properties of high lithium content and ordered intermetallic structure offer advantages in specific thermal, electrical, or mechanical contexts.

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.
