Description
Magnetic field shielding film MCF5 is a magnetic shielding film made from an amorphous cobalt alloy. For shielding of low-frequency alternating magnetic fields. Also shields low-frequency electric alternating fields (LF) and high-frequency fields (HF). Because MCF5 has a width of only 5 cm, its recommended for shielding smaller areas, e.g. in electronic applications or for cables.
Statical magnetic fields: Other than stated in the headline, this product is not MUMETALL®. We are utilizing a newer alloy which provides a better shielding. MUMETALL® is promoted to shield statical magnetic fields. The effect of the shielding is quite low indeed. We are using cobalt based alloy where the attenuation is increasing from strength to strength, with the velocity of the magnetic fields. There are no velocities with statical magnetic fields or by permanent magnets, that is why this product won´t shield those.
In comparison with MUMETALL® our MCF5 has many advantages: MUMETALL® is soft and sensitive, on bending, to shocks and on processing it looses the attenuation very fast. MCF5 stays flexible but hard even at small bending radii. The attenuation remains constant even at high mechanical stress. MCF5 can easily be cut with scissors.
