· JVASP-105219· NaAl3

NaAl3 is an intermetallic compound in the sodium-aluminum binary system, representing a research-phase material rather than a commercial engineering alloy. While intermetallic compounds of this type are investigated for lightweight structural applications and energy storage systems, NaAl3 itself has limited established industrial use; it is primarily of interest in materials research for understanding phase behavior in alkali-metal aluminum systems and exploring potential applications in specialized thermal or electrochemical contexts. Engineers would encounter this material mainly in academic or experimental settings rather than in conventional design specifications, though the broader family of aluminum intermetallics is relevant for aerospace and automotive weight reduction.

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.
