· JVASP-4310· Fe5Si3

Fe5Si3 is an iron-silicon intermetallic compound that belongs to the family of transition metal silicides, characterized by ordered crystal structures and high hardness. This material is primarily investigated in research and specialized industrial contexts for applications requiring exceptional stiffness and thermal stability, particularly where conventional steels prove insufficient. Fe5Si3 finds limited but strategic use in high-temperature structural applications, wear-resistant coatings, and as a reinforcement phase in composite materials, where its hardness and modest density offer advantages over pure metals, though its brittleness and processing challenges limit broader adoption.

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.
