· JVASP-90076· NbFeB

NbFeB is an intermetallic compound combining niobium, iron, and boron, belonging to the family of refractory metal borides and Fe-based alloys. This material is primarily of research interest for high-temperature applications and magnetic applications, where the combination of niobium's refractory properties and boron's hardening effect offers potential advantages in extreme environments or specialized functional applications compared to conventional steels or nickel-based superalloys.

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.
