· Fe4 B8

Fe4B8 is an iron-boron intermetallic compound belonging to the family of ferrous borides, which are ceramic-like materials combining metallic iron with boron to achieve enhanced hardness and wear resistance. This material is primarily of research and emerging industrial interest, particularly in wear-resistant coatings, hard-facing applications, and high-temperature structural components where superior hardness and thermal stability are required. Iron borides generally offer advantages over conventional steels in abrasive environments and are being investigated for advanced manufacturing applications, though commercial adoption remains limited compared to established coating systems and engineered ceramics.

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.
