· JVASP-16864· ErIn5Co

ErIn5Co is an intermetallic compound composed of erbium, indium, and cobalt, belonging to the rare-earth intermetallic family. This material is primarily of research and academic interest rather than established industrial production, and likely exhibits the high hardness, brittleness, and magnetic properties typical of rare-earth intermetallics. While not yet widely commercialized, compounds in this family are investigated for specialized applications requiring extreme hardness, thermal stability, or magnetic functionality where conventional alloys are insufficient.

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.
