    Material & Performance Characteristics

    Permalloy (such as 1J85 and 1J50) is a soft magnetic material with high magnetic permeability and low loss. This means that under the same magnetic field strength, permalloy can produce stronger magnetic flux density, thereby improving the efficiency and performance of electromagnetic components. The high magnetic permeability enables the laminated core to exhibit excellent magnetic properties even under low magnetic field intensity, making it suitable for various electromagnetic applications requiring high sensitivity and precision.

    In terms of manufacturing process, laminated cores are usually formed by welding or lamination riveting. These process methods are fast and efficient and can produce high-quality iron cores on a large scale. The welding process ensures that the various parts of the iron core are tightly combined to form a whole, thereby improving the mechanical strength and stability of the iron core. The laminated riveting process forms an integral iron core by stacking and riveting multiple thin sheets of material together. This method not only improves the mechanical strength of the iron core, but also effectively reduces eddy current losses.

    The application of laminated cores in electromagnetic components has significant advantages. Its high magnetic permeability, low losses and excellent mechanical properties make it ideal for a variety of electromagnetic components. Whether in transformers, magnetic amplifiers, or other electromagnetic applications, laminated cores can provide excellent performance and reliability to meet the needs of various high-performance electromagnetic components.

    Frequently Asked Questions (FAQ)
    Q What core materials are used for stacked iron cores?
    High magnetic permeability permalloy soft magnetic materials, such as 1J85, 1J50, and 1J79B grades, are primarily used to ensure high magnetic induction and minimal core loss.
    Q What are the primary applications of these laminated cores?
    They are widely used in critical electromagnetic components across electronic equipment, including power transformers, miniature transformers, precision sensors, reactors, chokes, and magnetic amplifiers.
    Q How does lamination riveting improve core performance?
    Lamination riveting tightly joins stacked thin sheets into an integral unit. This process not only enhances the mechanical rigidity and dimensional stability of the core but also effectively limits eddy current losses during operation.
    Q What is the difference between 1J79B and 1J85B grades?
    1J85B offers higher initial permeability (uo up to 65,000 Gs/Oe) and maximum permeability (um up to 250,000 Gs/Oe) with lower coercivity, making it ideal for ultra-sensitive applications, whereas 1J79B provides higher saturation magnetic hardness (7,500 Gs).
    Q Can custom dimensions and specifications be ordered?
    Yes, high customization is supported. Cores can be custom-manufactured using continuous punch mold tooling according to specific dimensional, strip thickness (0.05mm - 0.30mm), and electromagnetic requirements.
    Q Under what test conditions are the magnetic properties verified?
    The technical parameters and magnetic properties listed in the specification table comply with standard YB/T5251-2013 and are tested under DC (direct current) operating conditions.
