Our MuMetal ® alloy (mu-metal spec ASTM A753 , MIL-N-14411C) is a 80% Nickel soft magnetic alloy with very high permeability suitable for sensitive electronic equipment shielding. It 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), or fully annealed for maximum permeability. MuMETAL® is used for fabricated shields such as enclosures, cylinders, cans, channels or 3D boxes. Typically, final annealing in a hydrogen atmosphere furnace 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 our sheet or coil stock in gauges from 0.014" to 0.080" thickness [0,36mm to 2,00mm]. MuMETAL foil stock is fully annealed and available in gauges from 0.002" to 0.010" thickness [0,05mm to 0,25mm]. Foil is also available stress annealed by request.
MuMETAL® conforms to specs ASTM A753 Alloy 4 and MIL-N-14411C Composition 1
