PrYAl4
metal· JVASP-103056· PrYAl4
PrYAl4 is an intermetallic compound combining praseodymium (rare-earth element) with aluminum, belonging to the family of rare-earth aluminum intermetallics. This material is primarily of research and developmental interest rather than widespread commercial production, with potential applications in high-temperature structural applications and advanced aerospace systems where lightweight, thermally stable compounds are needed. The material's notable characteristic is the combination of rare-earth hardening with aluminum's low density, making it a candidate for exploring alternatives to conventional superalloys in specialized high-performance applications.

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.
