· ErNi9

ErNi9 is a rare-earth nickel intermetallic compound containing erbium and nickel in a nominal 1:9 atomic ratio. This material belongs to the family of rare-earth nickel systems, which are primarily investigated for specialized high-temperature and magnetic applications where the combination of rare-earth and transition-metal bonding provides unique phase stability and electronic properties. ErNi9 is predominantly a research material used in fundamental studies of intermetallic phase diagrams, magnetic behavior, and potential applications in advanced functional devices rather than high-volume industrial production.

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.
