Mu metal data sheet. Mu metal is a unoriented nickel iron soft ferromagnetic alloy with very high permeability suitable for sensitive electronic equipment shielding. Full magnetic anneal for maximum permeability. 4 data are typical of 014 0 36mm annealed sample and should not be construed as maximum or minimum values for specification or final design. Mumetal is used for fabricated shields such as enclosures cylinders cans channels or 3d boxes.

Mu metal is a unoriented nickel iron soft ferromagnetic alloy with very high permeability suitable for sensitive electronic equipment shielding. It is used primarily in low intensity magnetizing fields dc 100khz where high attenuation is desired high permeability high shielding efficiency. Available as stress annealed partially annealed for ease of machinability. This mu metal magnetic shielding foil is generous 8 wide by 12 long sheet that is 010 10 mil thick.

Data for each material thickness and or lot may vary. Mu metal is a 80 nickel 4 5 molybdenum balance iron soft ferromagnetic alloy which means that it does not retain a field after the removal of an external magnetizing force. Astm a 753 alloy 4 mil n 14411c composition. Technical data sheet mumetal is 80 nickel with additions of iron and molybdenum as main elements in turn this alloy offers an extremely high initial permeability.

Mu metal sheet magnetic shields are a leading supplier of magnetic shielding sheets. It is used primarily in low intensity magnetizing fields dc 100khz where high attenuation is desired high permeability high shielding efficiency. Very flexible and easy to cut with scissors. Mumetal conforms to astm a 753 alloy 4 and mil n 14411c composition 1 orders technical support p.

Mu metal offers exceptionally high initial and maximum permeability with minimum hysteresis loss. Mumetal stress annealed sheet is used primarily in low intensity fields where high attenuation is desired high initial permeability high shielding efficiency.
