MuMETAL® Alloy Foil (Ni80/Fe15/Mo5)

MuMETAL® Alloy Foil (Ni80/Fe15/Mo5) is a highly specialized soft magnetic material prized for its very high permeability, low coercivity, and superior shielding effectiveness against low-frequency magnetic fields. In foil form, it offers excellent flexibility and uniform coverage, making it an ideal choice for layered shielding systems and precision enclosures. Industries such as aerospace, defense, electronics, and medical technology integrate MuMETAL® foil into transformer shielding, magnetic housings for sensitive sensors, and magnetically shielded rooms where even slight interference can compromise accuracy. Specific applications include high-precision scientific instrumentation, magnetoencephalography (MEG) systems, and multilayer EMI shielding for low-noise electronics. Research highlights how the microstructure and grain orientation of MuMETAL® directly influence its permeability, and advanced processing methods such as annealing and controlled rolling are essential for maximizing performance. In research and industrial practice, MuMETAL® Alloy Foil is an indispensable material, enabling the development of highly stable, interference-free environments across the most demanding technological domains.
