· Al4Li9

Al4Li9 is an experimental lithium-aluminum intermetallic compound with a high lithium content, representing a research-phase material in the lightweight metal alloy family. While not yet a standard commercial alloy, compounds in this compositional range are of interest for ultra-lightweight structural applications where reducing density is critical, though brittleness and processing challenges have historically limited practical deployment. Engineers would consider this material primarily in advanced research contexts focusing on aerospace weight reduction or high-energy applications rather than conventional structural design.

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.
