Fe2Si
metal· Fe2Si
Fe2Si is an iron-silicon intermetallic compound that forms part of the iron-silicon phase diagram family. This material exhibits the rigid, brittle characteristics typical of intermetallics, with moderate density and significant elastic stiffness. Fe2Si appears primarily in materials science research and metallurgical applications where iron-silicon phases naturally form during processing or alloying, such as in cast irons, steel-silicon composites, and high-temperature structural studies; it is not commonly specified as a primary engineering material but rather emerges as a constituent phase in multi-component alloy systems where silicon addition is used for strengthening or thermal management purposes.

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.
