· JVASP-152644· ErCoSi

ErCoSi is an intermetallic compound combining erbium, cobalt, and silicon, representing a rare-earth transition metal silicide material. This is a research-phase compound studied for high-temperature structural applications where thermal stability and specific stiffness are critical; such rare-earth silicides are investigated as candidate materials for aerospace and power-generation environments where conventional alloys reach their performance limits. The erbium constituent provides potential benefits in thermal and magnetic properties, while the silicide matrix offers oxidation resistance and hardness—making the material family relevant to advanced engine components and thermal barrier systems.

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.
