    AI Overview
    High permeability permalloy strips (1J85/1J79) are iron-nickel (35-90% Ni) soft magnetic alloys with superior low-field permeability and low coercivity. Primarily used for magnetic shielding (e.g., 0.02-0.5mm foil) and transformer cores, these annealed strips offer low losses and high saturation induction, often used in precision electronics and sensors. 
    Key Characteristics and Types: 
    • 1J85 (Mu-Metal): Known for extremely high magnetic permeability in weak fields, ideal for sensitive shielding.
    • 1J50: Offers high saturation induction, suitable for high-performance transformers.
    • Composition: Typically ~80% Nickel (Ni) and Molybdenum (Mo) or Iron (Fe), often requiring annealing to maximize magnetic properties.
    • Physical Form: Supplied as foil or strip, commonly 0.02mm to 0.5mm thick, soft annealed to ensure ease of bending and shaping. 
    Common Applications: 
    • Magnetic Shielding: Used in EMI shielding for sensitive electronics, medical devices, and sensors, creating magnetic barriers that redirect magnetic fields.
    • Core Materials: High-precision current transformers, magnetic amplifiers, and inductors.
    • Industrial/Prototyping: Flexible for use by hobbyists and professionals in creating magnetic barrier parts. 
    Advantages: 
    • High Permeability: Allows high magnetic flux concentration.
    • Low Coercive Force/Low Loss: Enables high efficiency.
    • High Corrosion Resistance: Often enhanced by the annealing process. 
    Note: While some search results mention it in the context of furniture (due to misinterpretations of "magnetic shielding" strip edge finishing), permalloy's primary use is electromagnetic applications.

    What is the permeability of 1J85 permalloy?
    Magnetic Properties of 1J85 Permalloy

    | High Permeability: The permeability of the 1J85 alloy is very high, typically reaching above 10,000, and in some cases, between 100,000 and 150,000. This allows it to be rapidly and fully magnetized under the influence of a magnetic field, enhancing electromagnetic performance.
