MCL61 is a magnetic shielding material. Ideal protection from magnetic fields around electricity meters, circuit breaker panels, or electrical wiring. 


Made from an amorphous cobalt alloy, it is specifically designed to shield low frequency magnetic fields. At the same time this will also shield the area from electric and radio frequency fields.

The size is 1m x 0.61m.

Magnetic Shielding Film MCL61

  • Width: 61 cm
    Length: 1 metre, available by the running meter.
    Attenuation LF magnetic field: 30 dB (97 %); The attenuation depends on the number of phases,
    cable twisting, the size of the area, current draw etc.
    Attenuation HF: 40 dB at 1 GHz (see thumbnail graph)
    Weight: 265 g/m²
    Material thickness: 0.1 mm
    Colour: Silver
    Permeability: µ 2 = 10,000; µ 4 = 25,000; µ max. = 100,000; Saturation polarization: 0.55 T
    Materials: Polyester, Co69, Fe4, Mo4, Nb1, Si16, B7.


    MCL61 can easily be cut with scissors.
    Warning: The cutting edges are sharp like a knife!
    Important: Its difficult to glue the film free of creases, best cover the area with solid wall coverings.
    Wall, ceiling, floor: Best to use a high-viscous assembly adhesive, that adheres to non-absorbent substrates. Smooth the glue, lay up the film, smooth with a pressure roller or squeegee. The sheets of MCL61 should be overlapped.

    Due to the lamination MCL61 is corrosion-resistant even in humid environments.

    MCL61 is our novel magnetic shielding film made from an amorphous cobalt alloy for shielding of low-frequency magnetic fields. Also shields low-frequency electric fields (LF) and high-frequency fields (HF).
