· ErCu2

ErCu₂ is an intermetallic compound combining erbium (a rare earth element) with copper in a 1:2 stoichiometric ratio. This material belongs to the rare earth-copper intermetallic family, which exhibits unique combinations of magnetic, thermal, and electronic properties not readily available in conventional alloys. ErCu₂ and related rare earth copper compounds have attracted research interest for potential applications in high-temperature magnets, thermoelectric devices, and advanced functional materials where rare earth elements can be leveraged for enhanced performance.

Export Control

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.
