CaErAl4
metal· 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.
