· JVASP-101575· Li2SmAl

Li2SmAl is an intermetallic compound combining lithium, samarium (a rare-earth element), and aluminum. This is a research-phase material rather than an established commercial alloy, investigated primarily for lightweight structural applications and energy storage research where the combination of low density with rare-earth strengthening could offer advantages. The material family shows potential in aerospace and defense contexts where weight reduction is critical, though current development status and manufacturing scalability remain active research areas.

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.
