· JVASP-103464· LaPrAl4

LaPrAl₄ is an intermetallic compound combining lanthanum and praseodymium (rare earth elements) with aluminum, belonging to the family of rare-earth aluminum intermetallics. This material is primarily of research and developmental interest rather than established in high-volume production, studied for its potential in high-temperature applications and specialty alloy systems where rare-earth strengthening offers advantages over conventional aluminum 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.
