    AI Overview
    Mu Metal laminations are high-permeability, nickel-iron (permalloy) sheets (typically 0.2–0.35mm) stacked to create cores for high-end audio transformers, sensors, and magnetic shielding. Offering excellent inductance, minimal hysteresis, and superior magnetic shielding, they provide a path for magnetic flux around sensitive components, often used in EE or EI configurations. 
    This video explains how MuMetal provides magnetic shielding:

    Magnetic Motor - Shielding with MuMetal
    Mario Gudec
    YouTube• Feb 2, 2017
    Key Aspects of Mu Metal Laminations: 
    • Material Properties: Composed of 80% nickel-iron-molybdenum, these alloys provide extremely high initial and maximum permeability with minimal hysteresis losses.
    • Applications: Primarily used in audio transformers for high-fidelity sound, current sensors, clamp ammeters, and as shielding in sensitive electronics.
    • Lamination Types: Available in common configurations like EE type, EI type, or as custom-cut stacking cores, often using 0.2mm to 0.35mm thicknesses.
    • Performance Benefits: High shielding attenuation in low-intensity magnetic fields; they act as a magnetic shunt, redirecting flux around shielded areas.
    • Manufacturing: These parts are often processed through high-vacuum annealing to achieve peak magnetic performance, as material properties can be altered by bending or cutting.
    • Alternatives: While Mu Metal offers superior low-field shielding, Amorphous core transformers are often compared in audio applications based on desired sound weight. 
    Mu Metal laminations are frequently used in the automotive, audio, and power generation sectors, with suppliers offering specialized EI and ED shapes for specialized transformer, according to Hongertech.com.
