· JVASP-100415· CeYAl4

CeYAl4 is an intermetallic compound combining cerium, yttrium, and aluminum, representing a rare-earth-based metallic material system. This compound is primarily of research and developmental interest rather than widespread commercial use, investigated for potential applications in high-temperature structural materials and advanced alloy systems where rare-earth strengthening effects are desirable. The material belongs to a family of rare-earth aluminides being explored for aerospace and high-performance thermal applications, though practical engineering adoption remains limited compared to conventional superalloys.

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.
