WORLDWIDE MANUFACTURER and  DISTRIBUTOR Since 1941   Magnetic Shield Corporation, a division of Perfection Mica Company, is the premier supplier of custom magnetic shielding alloys and custom Built shields.


high permeability magnetic shielding alloys

Begin using one of our Lab Kits for evaluation, prototyping, and sampling. Then select and specify the alloy required for your application. Your prototype then serves as a production model. After prototyping, contact Magnetic Shield Corporation for a fabrication or stock material quotation. Magnetic Shield Corporation provides fabricated shields to thousands of customers worldwide!

MAGNETIC SHIELDING EFFICIENCY FOR WIRING APPLICATIONSWe offer several magnetic shielding products used in electrical / electronic wiring applications such as:  power feeds, aerospace,
vehicle controls, test and measurement devices, audio-level interconnections, communication equipment, and hand-held devices.
One of our outstanding products for reducing EMI is AA CABLE SHIELD®; specified regularly for these types of applications across a broad range of industries as listed below.
AA CABLE SHIELD® produced from Co-NETIC® AA high permeability 36AWG Wire and formed into a flexible braided weave sleeving, which is available in tubular continuous lengths.  Our AA CABLE SHIELD® unique design with a continuously enclosed shielding barrier manufactured with proprietary Co-NETIC® AA alloy has distinct advantages over foil wrapping or rigid channeling; and is used to avoid pickup of unwanted external H-fields (D.C. to 100 kHz), or to mitigate radiation from cable and conductors.  Co-NETIC® AA is used primarily in low intensity fields where high attenuation is desired (high initial permeability & high shielding efficiency).  Braid is tightly weaved, so shield coverage is 90% at nominal linear state.  In addition, Co-NETIC® AA wire is corrosion resistant.  Three stock diameters are available and cut to length.

Sample:  A sample of the AA CABLE SHIELD® is included in our Lab Kits.

Experimentation, testing, and prototyping typically begins with our "hands-on" Evaluation Kits.  Our kits include several sizes and thicknesses of material to create usable shields.
