· JVASP-93328· ErCo2

ErCo2 is an intermetallic compound combining erbium (a rare-earth element) with cobalt in a 1:2 stoichiometric ratio. This material belongs to the family of rare-earth transition-metal intermetallics, which are typically studied for their magnetic, thermal, and mechanical properties at elevated temperatures. ErCo2 is primarily of research and specialized industrial interest rather than a commodity material, valued for applications requiring materials that combine rare-earth magnetic characteristics with cobalt's thermal stability and strength contributions.

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.
