General Description
Mu 80 is a nickel-iron-molybdenum alloy with very high initial and maximum magnetic permeabilities and minimal core losses at low field strengths. This vacuum-melted product also offers the advantages of small size and weight in magnetic core and shielding materials. Due to its high magnetic permeability it is used in manufacturing transformers and inductors. Mu 80 is also used as a component for both saturating and non-saturating application.
