metal· Fe0.998Co0.002Si2
Fe0.998Co0.002Si2 is an iron-cobalt silicide intermetallic compound with cobalt as a minor alloying addition to an iron disilicide base. This material belongs to the family of transition metal silicides, which are typically evaluated for high-temperature structural applications and electronic device applications due to their ceramic-like hardness combined with metallic conductivity. The minimal cobalt doping (0.2%) suggests this is likely a research composition designed to modify the properties of iron disilicide for specific engineering requirements, such as improving oxidation resistance, thermal stability, or electrical characteristics compared to undoped Fe-Si2.

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.
