· Li1 Mg2 Al1

Li₁Mg₂Al₁ is a lightweight intermetallic compound combining lithium, magnesium, and aluminum—three of the lightest structural metals. This ternary alloy composition represents a research-phase material intended to explore ultra-low-density structural solutions, as the lithium content significantly reduces overall density while magnesium and aluminum provide strength and workability. While not yet widely commercialized, materials in this family are investigated for aerospace weight reduction, portable energy systems, and high-performance applications where density penalty is critical; however, challenges with lithium reactivity, casting difficulty, and phase stability typically limit current industrial adoption compared to conventional Al-Mg or Mg-based alloys.

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.
