· JVASP-107561· FeCoB2

FeCoB2 is an iron-cobalt boride intermetallic compound belonging to the family of transition metal borides. These materials are typically investigated for their potential to combine the ferromagnetic properties of iron-cobalt with the hardness and thermal stability imparted by boron, making them candidates for high-performance magnetic and wear-resistant applications. While FeCoB2 remains primarily a research-phase material rather than a widely commercialized engineering alloy, boride compounds in this family are of interest where engineers need materials that operate at elevated temperatures with resistance to mechanical wear or magnetic degradation.

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.
