· ErAg2

ErAg2 is an intermetallic compound combining erbium (a rare-earth element) with silver in a 1:2 stoichiometric ratio. This material belongs to the rare-earth–transition metal intermetallic family, which exhibits unique combinations of mechanical and thermal properties due to the strong metallic bonding between the lanthanide and noble metal components. ErAg2 remains primarily a research material rather than a commodity in widespread industrial production; it is studied for specialized high-performance applications where the synergistic properties of erbium and silver offer advantages over conventional alloys.

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.
