CrFeCoSi
metal· JVASP-100308· CrFeCoSi
CrFeCoSi is a quaternary high-entropy alloy (HEA) combining chromium, iron, cobalt, and silicon in roughly equal atomic proportions. This material belongs to an emerging class of compositionally complex alloys designed to achieve strength, hardness, and thermal stability through entropy-stabilized solid solutions rather than traditional strengthening mechanisms. While primarily in research and development phases, CrFeCoSi and related HEAs are being investigated for structural applications requiring exceptional hardness and wear resistance at elevated temperatures, positioning them as potential alternatives to conventional superalloys and stainless steels in demanding environments.

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.
