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).

Magnetic Capabilities and Mechanical Properties of Mu-Metal. MuMETAL® Chemical Composition % In Weight* Nickel (Ni) 80-82% Molybdenum (Mo) 3.5-6%

Mu-Metal is used primarily in fields of low intensity because of their high attenuation characteristics. Soft iron finds application in fields of high intensity because of its high magnetic saturation characteristics.

What is magnetic permeability? μ (Mu) – The 12th letter of the Greek alphabet, is used in physics and engineering formulae to represent permeability, the measure of a material’s ability to support the formation, or absorption, of a magnetic field within itself.
