MuMETAL® for Fabricating Magnetic Shielding

Service Detail from Magnetic Shield Corporation


MuMETAL® is our most widely known brand, yet Magnetic Shield Corporation offers several other alloys which are used for similar, but different applications. MuMETAL® Stress Annealed sheet is used primarily in low intensity fields where high attenuation is desired (high initial permeability & high shielding efficiency). Available as stress annealed (partially annealed for ease of machinability). MuMETAL® is used for fabricated shields such as enclosures, cylinders, cans, channels or 3D boxes. Typically, atmospherically controlled Perfection Annealing is required after stamping, machining, bending, rolling or welding to provide maximum shielding performance.

MuMETAL® alloy is available in many forms, but most shields are fabricated from either our plate, sheet or coil stock. Our supply is stocked in select gauges; sheet in gauges 0.014" to 0.080" thickness [0,36mm to 2,00mm], plate in gauges from 0.098" to 0.197" thickness [2,5mm to 5,0mm], and foil in gauges from .002" to .010" thickness [0,05mm to 0,25mm].
