NickelIron MuMetal wire mesh/screen
Nickel Iron MuMetal wire mesh/screen offers important electromagnetic field shielding characteristics, including very high magnetic permeability - its ability to absorb magnetic energy. The unique properties of
MuMetal wire mesh results in the highest possible attenuation, making these shielding alloys the materials of choice for reducing low-frequency electromagnetic interference (EMI).
To ensure the quality of our product, we can produce the product with raw materials from the international suppliers. Every batch of product can be tracked to the original raw material supplier. We co-operate with international suppliers like Allvac(ATI), Bohler, Carpenter, Dunkirk, Gloria, OttoKumpu, SMC, ThyssenKrupp VDM, Valbruna, etc.

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
