· JVASP-108801· CaErAl4

CaErAl4 is an intermetallic compound containing calcium, erbium, and aluminum, belonging to the rare-earth metal alloy family. This material remains primarily in the research and development phase, with potential applications in high-temperature structural applications and specialty aerospace components where rare-earth reinforcement could provide enhanced properties. The incorporation of erbium—a lanthanide element—suggests investigation into thermal stability, creep resistance, or specialized magnetic or electronic properties that distinguish it from 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.
