· Er1 Co3 B2

Er₁Co₃B₂ is an intermetallic compound combining erbium, cobalt, and boron, belonging to the rare-earth transition metal boride family. This material is primarily of research interest rather than established industrial production, investigated for its potential in high-performance applications where magnetic properties, thermal stability, or hardness from the boride phase may be beneficial. The erbium-cobalt-boron system represents an emerging materials class for applications requiring combinations of magnetic ordering, mechanical stiffness, and rare-earth functionalization.

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.
