· JVASP-11483· MnFe2O4

MnFe2O4 is a manganese iron oxide ceramic belonging to the spinel ferrite family, characterized by a mixed-valence transition metal oxide structure. It is primarily used in electromagnetic and magnetic applications, including soft magnetic cores for inductors and transformers, microwave absorbers, and magnetostrictive devices. This material offers good magnetic permeability, moderate saturation magnetization, and relatively low eddy current losses compared to iron-cobalt alternatives, making it attractive for high-frequency electronic components and electromagnetic shielding where cost and processing ease are balanced against performance requirements.

Regulatory Screening

Environmental

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.
