FeB
metal· FeB
FeB is an iron-boron intermetallic compound belonging to the family of iron-boron phases, characterized by a defined stoichiometric ratio of iron to boron atoms. This material exhibits high hardness and stiffness, making it relevant in wear-resistant and high-strength applications where brittleness can be managed through composite design or controlled processing. FeB is investigated primarily in research contexts for hard coatings, cutting tools, and armor systems, where its extreme hardness offers potential advantages over conventional tool steels and cemented carbides, though industrial adoption remains limited due to processing challenges and fracture sensitivity.

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.
