MuMetal Sheet Plate Strip
MuMetal Sheet Plate Strip offers important electromagnetic field shielding characteristics, including very high magnetic permeability - its ability to absorb magnetic energy. The unique properties of MuMetal sheet results in the highest possible attenuation, making these shielding alloys the materials of choice for reducing low-frequency electromagnetic interference (EMI).

Uses and properties:-
Mu-metal is used to shield equipment from magnetic fields. For example:
1. Electric power transformers, which are built with mu-metal shells to prevent them from affecting nearby circuitry
2.Hard Drives, which have mu-metal backings to the magnets found in the drive to keep the magnetic field away from the disk.
3.Cathode-ray tubes used in analogue oscilloscopes
4.Magnetic phonograph cartridges, which have a mu-metal case to reduce interference when LPs are played back
5.Magnetic resonance imaging equipment
6.The magnetometers used in magnetoencephalography and magnetocardiography
Photomultiplier tubes
7. Vacuum chambers for experiments with low-energy electrons, for example photoelectron spectroscopy
8.Superconducting circuits and especially Josephson junction circuits
