· Fe4 B4

Fe4B4 is an iron boride compound belonging to the family of transition metal borides, which are intermetallic ceramics known for their exceptional hardness and high melting points. This material is primarily of research and developmental interest rather than established in widespread industrial production, with potential applications in hard coating materials, wear-resistant components, and high-temperature structural applications where the iron-boron system offers advantages in cost and thermal stability compared to other refractory borides. Iron borides are investigated as candidates for cutting tools, abrasive applications, and protective surface coatings in extreme environments.

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.
