Mu Metal Data Sheet

Mu metal is a unoriented nickel iron soft ferromagnetic alloy with very high permeability suitable for sensitive electronic equipment shielding.

Mu metal data sheet.

Technical data shielding fundamentals faqs contact mu metal foil. 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. Full magnetic anneal for maximum permeability. Mumetal conforms to astm a 753 alloy 4 and mil n 14411c composition 1 orders technical support p.

Available as stress annealed partially annealed for ease of machinability. Astm a 753 alloy 4 mil n 14411c composition. Our standard stock range of mu metal cryogenic mumetal 36 50 ni fe and pure iron are available for rapid delivery worldwide and these materials can be supplied in a wide range of sizes gauges and quantities. 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. Mu metal sheet magnetic shields are a leading supplier of magnetic shielding sheets. Very flexible and easy to cut with scissors. Mumetal is used for fabricated shields such as enclosures cylinders cans channels or 3d boxes.

It is used primarily in low intensity magnetizing fields dc 100khz where high attenuation is desired high permeability high shielding efficiency. Typical magnetic properties dc μ 40 gauss 80 000 dc μ 100 gauss 105 000 dc μ maximum 400 000 dc hc 0 007 oe 0 6 a m dc br gauss 4 000. Mu metal is a unoriented nickel iron soft ferromagnetic alloy with very high permeability suitable for sensitive electronic equipment shielding. Used for shielding sensitive electronic devices from unwanted electromagnetic interference.

Data for each material thickness and or lot may vary. 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.
