· Co2FeSi

Co₂FeSi is an intermetallic compound belonging to the Heusler alloy family, characterized by a specific stoichiometric composition of cobalt, iron, and silicon atoms arranged in an ordered crystal structure. This material is primarily investigated in research and specialized applications for its ferromagnetic properties and potential as a half-metallic ferromagnet, making it attractive for spintronics and magnetic device applications where high spin polarization is desired. Co₂FeSi and related Heusler alloys are less common in mainstream industrial production compared to conventional ferromagnetic alloys, but represent an emerging class of functional magnetic materials for next-generation electronics and sensing systems.

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.
