MuMETAL® Stress Annealed alloy is available in many forms, but most shields are fabricated from our sheet stock in gauges from .014" to .062" thickness [0,36mm to 1,57mm]. MuMETAL® Foil is fully annealed and available in stock gauges from .002" to .010" thickness [0,05mm to 0,25mm].
Mu-Metal - an overview ScienceDirect TopicsA high-permeability material such as mu-metal or its derivatives can give LF magnetic shielding by concentrating the field within the bulk of the material, but this is a different mechanism to that discussed above, and it is normally only viable for sensitive (or noisy) individual components such as transformers.

Magnetic ShieldingHistoryUses and PropertiesSimilar MaterialsThe high permeability of mu-metal provides a low reluctance path for magnetic flux, leading to its use in magnetic shields against static or slowly varying magnetic fields. Magnetic shielding made with high-permeability alloys like mu-metal works not by blocking magnetic fields but by providing a path for the magnetic field lines around the shielded area. Thus, the best shape for shields is a closed container surrounding the shielded space. The effectiveness of mu-metal shielding decreases with the alloy's perMagnetostriction - Engineering LibreTextsOct 21, 2020 · Magnetostriction is a property of ferromagnetic materials which causes them to expand or contract in response to a magnetic field. This effect allows magnetostrictive materials to convert electromagnetic energy into mechanical energy.
MuMETAL has a much higher permeability at lower magnetizing force, but saturates at a much lower flux density compared to steel. There are actually two material properties that help us understand the performance of these shielding materials, Mu-Metal vs. steel. The first is Permeability .
MuMETAL® High Permeability Magnetic Shielding Alloy MuMETAL ® magnetic shielding alloy (mu metal grade ASTM A753 Alloy 4, UNS N14080, 80NiFe) is our most widely known brand. Mu-Metal is a unoriented nickel-iron soft ferromagnetic alloy with very high permeability suitable for sensitive electronic equipment shielding. It is used primarily in low intensity magnetizing fields (DC-100kHz) where high attenuation is desired (high permeability & high
MuMETAL® Magnetic Shielding ASTM A753 - HomeThe final annealing treatment is paramount to the magnetic properties of Mumetal. The permeability of the cold rolled state increases by more than three orders of magnitude after final annealing. MuMETAL® alloy is available in many forms, but most shields are fabricated from our sheet or coil stock in gauges from 0.014" to 0.080" thickness [0
May 12, 2015 · Through composition and annealing, MuMetal receives essential electromagnetic shielding properties and extremely high magnetic permeability- absorbs magnetic energy. The exclusive characteristics of this alloy offer the maximum feasible attenuation, making it the best material for choosing to decrease low frequency electromagnetic interference.
Mumetal from MuShield Magnetic Shielding - Made in USAMumetal is a soft ferromagnetic material that does not retain a macroscopic internal field after the removal of an external magnetizing field. Most alloys are permalloys meeting spec ASTM A753 Alloy Type 4 and containing approximately 80% Nickel (Ni), 20% Iron
