ErCoSi2
metal· JVASP-86393· ErCoSi2
ErCoSi2 is an intermetallic compound composed of erbium, cobalt, and silicon, belonging to the rare-earth transition metal silicide family. This material is primarily of research and developmental interest rather than established industrial production, explored for high-temperature structural applications where its intermetallic nature offers potential for strength retention and oxidation resistance at elevated temperatures. Silicide compounds like ErCoSi2 are investigated as alternatives to conventional superalloys in aerospace and energy applications, though their brittleness and processing challenges have limited widespread adoption compared to Ni-based superalloys.

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.
