· JVASP-153043· ErNi4

ErNi₄ is an intermetallic compound in the erbium-nickel system, belonging to the rare-earth transition-metal alloy family. This material is primarily of research and specialized application interest, valued for its magnetic properties and potential use in high-temperature applications where rare-earth strengthening of nickel-based matrices is desired. ErNi₄ represents a niche material class useful in permanent magnets, magnetic refrigeration systems, and advanced metallurgical research exploring rare-earth stabilized phases.

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.
