· JVASP-111355· MnFeB

MnFeB is a manganese-iron-boron alloy that belongs to the ferromagnetic metal family, combining iron's magnetic properties with manganese and boron to modulate hardness, saturation magnetization, and thermal stability. This material is primarily investigated for soft magnetic applications where low coercivity and high permeability are valuable, including electromagnetic devices, magnetic cores in power electronics, and potential use in permanent magnet systems where boron addition enhances magnetic energy density. Compared to pure iron or conventional silicon-steel laminations, MnFeB offers tunable magnetic performance through composition adjustment, making it relevant to researchers and engineers optimizing efficiency in transformers, inductors, and next-generation magnetic actuators.

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.
