· JVASP-95057· Fe2Ni

Fe2Ni is an intermetallic compound composed of iron and nickel in a 2:1 stoichiometric ratio, belonging to the class of ordered metallic compounds that exhibit distinct crystal structures and properties distinct from simple solid solutions. This material is primarily of interest in research and specialized applications where the unique combination of ferromagnetic properties, ordered crystal structure, and intermediate density between pure iron and nickel can be leveraged. Fe2Ni is explored in contexts ranging from magnetic device applications to advanced structural alloys, though it remains less common than conventional Fe-Ni solid solutions in mainstream engineering use.

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.
