· CoFeSi

CoFeSi is a ternary intermetallic compound combining cobalt, iron, and silicon, belonging to the family of transition metal silicides. This material is primarily of research and emerging industrial interest for high-temperature structural applications, magnetic devices, and wear-resistant coatings due to the favorable combination of thermal stability and mechanical properties that cobalt-iron silicides can offer compared to binary silicides.

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.
