NiFe-based Mu Metal Shielding Cover

Mu Metal has very high magnetic permeability compared to other materials. Permeability is the degree of magnetization of a material that responds linearly to an applied magnetic field. Mu Metal can divert magnetic flux and effectively protect sensitive components from near by magnetic source.

Below chart compares permeability of selected materials for reference:
Material Susceptibility (Xm) Permeability (μ)×10-6 Magnetic field
Mu Metal 20000[1] 25000 N/A2 @0.002T
Permalloy 8000[1] 10000 N/A2 @0.002T
Transformer iron with ρ=0.01 μΩ·m 4000[1] 5000 N/A2 @0.002T
Steel 700[1] 875 N/A2 @0.002T
Nickel 100[1] 125 N/A2 @0.002T
Platinum 2.65×10-4 1.2569701 N/A2
Aluminum 2.22×10-5[2] 1.2566650 N/A2

An electromagnetic wave can be divided into electric field and magnetic field. Magnetic field is reportedly more harmful to the human body than an electric field. Electric field (RF) can be effectively shielded by conductive material properly grounded, but the magnetic field is not easily shielded and requires highly permeable material such as Mu Metal or permalloy. By heat treating Mu Metal Shielding covers at high temperature, these metals’ magnetic shielding performance reaches about 96%, while high performance comes with high price. Our Mu Metal Shielding covers, made with a newer technique, are available at reasonable prices.

Made with special high temperature to produce superior shielding capability against a magnetic field, our Mu Metal can be easily made into many other forms and shapes by die-press, soldering and cutting.
