· LaAl4

LaAl4 is an intermetallic compound in the lanthanum-aluminum system, representing a rare-earth metal alloy with potential for lightweight structural and functional applications. This material exists primarily in research and development contexts rather than widespread commercial production, with interest centered on its unique combination of rare-earth and aluminum constituents for advanced aerospace, catalytic, and high-temperature applications. Engineers evaluating LaAl4 should recognize it as an emerging material in the rare-earth intermetallic family, where the low density relative to rare-earth bulk metals and potential for thermal stability may offer advantages in specialized high-performance environments where cost and maturity are secondary to novel property combinations.

Export Control

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.
