· ErCo3

ErCo3 is an intermetallic compound combining erbium (a rare-earth element) with cobalt in a 1:3 stoichiometric ratio. This material belongs to the rare-earth intermetallic family and is primarily of research and specialized industrial interest rather than a commodity engineering material. ErCo3 exhibits magnetic properties typical of rare-earth–transition-metal compounds, making it relevant for applications requiring controlled magnetic behavior, high-temperature stability, or specific electronic properties; it is notably denser than many structural metals and represents a niche alternative where rare-earth magnetism or thermal characteristics outweigh cost and availability concerns.

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.
