Fe13Co3
metal· Fe13Co3
Fe13Co3 is an iron-cobalt intermetallic compound that combines the ferromagnetic properties of iron with cobalt's enhanced magnetic strength and thermal stability. This material is primarily explored in research and advanced applications requiring high magnetic performance, such as soft magnetic cores, electromagnetic devices, and high-temperature magnetic applications where conventional Fe-Si steels reach their limits. The cobalt addition improves saturation magnetization and Curie temperature compared to pure iron, making it attractive for precision electromagnetic and power conversion systems, though it remains largely in development or specialized industrial use rather than mainstream commodity applications.

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.
