PrAl4
metal· JVASP-4394· PrAl4
PrAl4 is an intermetallic compound combining praseodymium (a rare-earth element) with aluminum in a 1:4 stoichiometric ratio. This material belongs to the rare-earth aluminium intermetallic family, which exhibits high stiffness and relatively low density, making it of research interest for lightweight structural applications. While not yet established in mainstream production, PrAl4 represents the broader class of rare-earth intermetallics being investigated for high-temperature and aerospace contexts where weight savings and stiffness are critical design drivers.

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.
