    MCF5, LF Magnetic Shielding Film, Width: 5cm

    MCF5 is a magnetic shielding film made from an amorphous cobalt alloy for shielding of low-frequency alternating magnetic fields.
    Please note: Permanent magnets (magnetic DC fields) are not shielded!
    Because it is a metallic product if used in terms of surface area and if it is grounded accordingly it also shields low-frequency electric alternating fields (LF) and high-frequency fields (HF).
    Because MCF5 has a width of only 5 cm, it is recommended for shielding smaller areas, e.g. in electronic applications or for cables.
    In comparison with MUMETALL® the new 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.
    This film is only available in lengths of  1m, 20m or 100m at a stretch.
    Lengts of i.e. 5m are supplied as 5 x 1m.
    The order quantities of 20m and 100m offer interesting price advantages per running metre!

    Technical data:
    • Width: 5 cm
    • Length: 1 linear meter = 0.05 m²
    • Attenuation LF magnetic field: 30 dB (97 %)
    • Attenuation HF: 40 dB at 1 GHz
    • Weight: 180 g/m²
    • Material thickness: 0.02 mm
    • Color: Silver
    • Permeability: µ 4 = 25,000; µ max. = 100,000
    • Saturation polarization: 0.55 T
    • Composition: Co69, Fe4, Mo4, Nb1, Si16, B7
    Warning: The cutting edges are sharp as a knife!
    Best use our plastic scraper FVR10 to press it on the adhesive tapes or into the glue, this is the safe way to keep your fingers! There is no self ashesive version available. However, bonding is easily possible: Please use a double sided adhesive tape e.g. Carpet adhesive tape with 50 mm width or a wider double-sided adhesive tape. Otherwise a commercial surface contact adhesive can be used (e.g. UHU, PATTEX).
    Due to the conductive surface this material can be contacted and grounded easily to shield low frequency (LF) electric fields.
    Shielding attenuation:
    The shielding attenuations are regularly tested in the manufacturer's own laboratory, HF due to ASTM D4935-10, the LF magnetic field due to ASTM A698/A698M-07.
