· JVASP-150752· FeB4

FeB4 is an iron boride intermetallic compound belonging to the family of transition metal borides, which are characterized by high hardness and thermal stability. This material is primarily of research and development interest rather than widely established in production, with potential applications in wear-resistant coatings, hard-facing alloys, and high-temperature structural applications where the boron-iron bonding provides enhanced mechanical performance. Engineers would consider FeB4 for specialized applications requiring extreme hardness and resistance to thermal cycling, though commercial availability and processing routes remain limited compared to established hard-coating alternatives like tungsten carbide or chromium borides.

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.
