MuMetal^® magnetic shielding prevents magnetic fields from reaching areas where they would cause magnetic interference. Magnetic shielding is used around either the source of interference, to prevent electromagnetic radiation from leaving a device; or more typically, around a sensitive device, to prevent the electro magnetic interference (EMI) from disrupting normal operations.

MuMetal magnetic shielding meets MILSPEC 14411C, composition 1, and possesses exceptionally high magnetic permeability, very low coercive force, very low core losses, and low remanence by magnetic field annealing.

Magnetic Shield Corporation is the oldest company devoted exclusively to solving problems of magnetic interference. Our materials have been involved in thousands of applications. Our quality and processes are world-class. Hundreds of customers have made us their Preferred Source for MuMetal and our proprietary brands of NETIC^® and CO-NETIC^® magnetic shielding material. You will find answers dealing with your problems of Electro Magnetic Interference (EMI) in the FAQ section of this site; or, you may CHAT with our sales managers (see right) during business hours.

When MuMetal is specified, Magnetic Shield Corporation delivers the authentic material.
