    AI Overview
    EL Mu-metal (80% nickel-iron alloy) laminations are premium transformer core materials, offering extremely high permeability (approx. 100,000) for superior magnetic shielding and high-efficiency, low-loss performance in high-end audio, sensors, and sensitive electronic applications. These EL-shaped laminations, typically 0.2 mm to 0.35 mm thick, are designed for precision, minimizing magnetic fields in compact designs. 
    This video explains what MuMetal is and how it is used for magnetic shielding:

    RC Quick Tips: What is MuMetal?
    Painless360
    YouTube• Dec 20, 2016
    Key Features & Applications 
    • High Permeability: Offers maximum permeability with minimum hysteresis loss, making them superior for low-level signal transformers.
    • Audio Transformer Use: Widely used in high-end audio equipment for better induction and stable performance.
    • Shielding Capabilities: Used in EI-type laminations to provide high-efficiency shielding, often in specialized or high-sensitivity applications.
    • Specifications: Commonly available in nickel-iron (Ni80 or Ni78-80%) grades. 
    EL Mu-metal Lamination Advantages 
    • Improved Sound: Often provides a "fuller body" with added warmth in audio transformers compared to amorphous cores.
    • High Efficiency: The high nickel content provides superior magnetic properties for sensitive applications.
    • Customizable: Available in various EI shapes, allowing for custom transformer designs that require minimal stray magnetic fields. 
    Common manufacturers and suppliers for these specialized laminations include Hongertech and Selmag Enterprise Co., Ltd..
