Fe2B
metal· Fe2B
Fe2B is an iron boride intermetallic compound that forms as a hard, brittle phase in iron-boron systems. It is primarily encountered as a constituent in surface hardening treatments, boronized coatings, and wear-resistant composite materials rather than as a bulk engineering alloy. Fe2B is valued for its exceptional hardness and is generated during pack boronizing or gas boronizing processes to create wear-resistant surface layers on steel components; it is also used in research contexts to develop hard composite materials and thermal management applications where boride phases provide superior wear and thermal properties compared to conventional surface treatments.

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.
