ErFe2Co2B
metal· JVASP-145750· ErFe2Co2B
ErFe2Co2B is an intermetallic compound belonging to the rare-earth transition metal boride family, combining erbium with iron, cobalt, and boron elements. This material is primarily of research and development interest for high-performance magnetic and hard-facing applications, where the rare-earth and transition metal constituents are expected to provide enhanced magnetic properties or wear resistance compared to conventional ferrous alloys. The erbium addition distinguishes this composition within the broader class of cobalt-iron-boron magnetic materials, making it relevant for advanced permanent magnet or magnetocaloric device research rather than established 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.
