WORLDWIDE MANUFACTURER and DISTRIBUTOR Since 1941Magnetic
Shield Corporation, a division of Perfection Mica Company, is the
premier supplier of custom magnetic shielding alloys and custom-built
MuMETAL® Foil is fully Annealed and used primarily in low intensity fields where the highest attenuation, highest initial permeability µ (Mu) and highest shielding efficiency are desired. MuMETAL® Foil is available in stock gauges from 0.002" to 0.010" thickness [0,05mm to 0,25mm].
Foils can be slit to a minimum width of 1/4" (6,35mm). Foil width tolerance is ±0.010" (0,25mm).
Unlike MuMETAL® Stress Annealed Sheet, our Foils do not require re-annealing unless severe forming or heliarc welding is performed.
Note: Priced per linear foot. Volume discounts available.
MuMETAL® is used primarily in low intensity fields where high attenuation is desired (high initial permeability & high shielding efficiency). Our MuMETAL® Deep Draw Coil is available for stamping and forming of shielding cans. Typically, atmospherically controlled Perfection Annealing is required after stamping, deep drawing, machining, bending, rolling or welding to provide maximum shielding performance.
MuMETAL® Deep Draw Coil supply is stocked in gauges from 0.014" to 0.025" thickness [0,36mm to 0,64mm] and 12” wide. Coil can be slit to your tooling width at a minimum width of 1/4" (6,35mm).
Note: Priced per linear foot. Volume discounts available.
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 ...
MuMETAL® Round Bar is primarily used for machined or forged components like current sensors, high precision current transformer cores, ground fault circuit breaker (relay parts), or any other applications requiring precision machined, high permeability soft magnetic alloy, with a low coercive force and low losses, in the range from 0-100 kHz. Typically, atmospherically controlled Perfection Annealing is required after machining, forming, forging, or welding to provide maximum shielding performance.
Our MuMETAL® Round Bar is stocked in diameters from 0.250" to 8.17" [6,35mm to 207,5mm]. Custom diameters and lengths are available upon request.
Note: Priced per linear Inch. Volume discounts available.
We offer a wide range of 5-sided magnetic shielding MuMETAL® Cans stamped or formed in either ROUND or RECTANGULAR shapes, and deep-drawn up to a 3:1 depth ratio when necessary. Our standard stock range and custom sizes are available in thicknesses from 0.014’’ to 0.062’’ [0,36mm to 1,57mm thick] and made from various MuMETAL®, Co-NETIC® or NETIC® shielding alloys depending on your exact shielding requirements. Typically, our high permeability (µ) 80% nickel-iron MuMETAL® cans are shipped as is since our AA Perfection Annealing method provides a bright nickel appearance after anneal. We do offer other finishes including plating, electro-polish, powder coating and ...
Magnetic Shield Corporation supplies tape-wound MuMETAL® Toroidal Cores to industries requiring High Metering Accuracy (HMA) current transformer cores. By using our proprietary brand of MuMETAL® and properly heat treating in a controlled hydrogen atmosphere furnace, (to a soft magnetic anneal) we maintain close control of the magnetic properties over a broad range of flux densities which permits the most economical and efficient design of your transformer.
We offer a range of wound cores from minimum 1” [25mm] inside diameter to maximum 47.25” [1200mm] outside diameter, using MuMETAL® foil thicknesses ranging between 0.004” [0,1mm] and 0.014” [0,36mm]. Core height is available from ...
One of our most popular research products, fabricated from MuMETAL® alloy is the Magnetic Shield Corporation Zero Gauss Chamber. These scientifically engineered chambers provide a laboratory work space of extremely low magnetic field.
MuMETAL® Zero Gauss Chambers have been used worldwide by many universities, private research companies, national laboratories and companies required to provide evidence of military or consumer regulatory compliance. Our chambers are preferred because they are made from high permeability (µ) Stress Annealed MuMETAL®, which provides a consistent, low field test area.
Our standard Zero Gauss Chambers consist of 3-layers and are designed to attenuate external low frequency A.C. ...
We design and build both modular “MuRooms®” and Custom MuRooms® based upon each customer’s unique application or requirements to create a low field environment. One of our specialty high permeability and high attenuation alloy materials may be specified and employed for construction; either MuMETAL® Sheet with Perfection Annealing applied or our stock Co-NETIC® AA Perfection Annealed Sheet.
After taking measurements of electromagnetic field (EMF) radiation generated by external sources and establishing the main source(s) of unwanted electromagnetic fields in the designated space, we will provide an efficient solution to mitigate the electro-magnetic interference that is occurring. ...
