MCF5 is a low cost adhesive magnetic shielding film made from an amorphous cobalt alloy for shielding of low-frequency alternating magnetic fields. It 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.

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.

Processing

Warning: The cutting edges are sharp as a knife! Best use our plastic scraper FVR10 to press it on the adhesive tapes or onto the glue, this is the way to keep your fingers safe. There is no self adhesive version available. To bond this product 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).

Grounding

Due to the conductive surface this material can be contacted and grounded easy to shield low frequency (LF) electric fields.
