    Other shields are typically made from high magnetic permeability 1J85 material, which has high magnetic permeability and extremely low coercivity. In weak magnetic fields, it exhibits excellent shielding and anti-interference capabilities. It is mainly used for anti-interference protection of various equipment and electronic components in strong magnetic environments. It is widely used in various electromagnetic occasions and various types of transformers, sensors and other equipment.

    1J85 material is a high magnetic permeability alloy, usually composed of nickel and iron, with extremely high magnetic permeability and low coercive force. This makes it excellent at shielding weak magnetic fields and reducing electromagnetic interference. Other shielding covers are designed to not only effectively shield external magnetic fields, but also prevent magnetic fields generated by internal equipment from interfering with the outside world.

    These shields are produced by die stamping, ensuring precise dimensions and consistent quality. After high-temperature heat treatment, the magnetic shielding effect of the shielding cover has been further improved. This production process not only improves the mechanical strength of the shield, but also enhances its stability and durability in complex electromagnetic environments.

    In practical applications, other shields can be used to protect sensitive electronic components, such as precision sensors, signal processors and communication equipment, to ensure that they can operate normally in strong magnetic environments. In addition, they can also be used in power equipment such as transformers and inductors to reduce magnetic field leakage and improve equipment efficiency and safety.

    Frequently Asked Questions (FAQ)

    What materials are typically used for other shielding covers?
    Other shielding covers are generally made from high magnetic permeability alloys such as 1J85 and 1J79, which consist mainly of nickel and iron. These materials offer extremely high magnetic permeability and low coercivity, making them ideal for shielding weak magnetic fields.
    What are the primary applications for these magnetic shields?
    They are widely used to protect sensitive electronic components, precision sensors, signal processors, communication equipment, and power devices like transformers and inductors from electromagnetic and magnetic interference in strong magnetic environments.
    What thickness options are available for customization?
    To meet diverse customer specifications, shielding covers are available in various thicknesses, commonly including 0.5mm, 0.8mm, 1.0mm, 1.2mm, and 1.5mm. Custom dimensions and shapes can also be produced via mold stamping.
    How does high-temperature heat treatment affect the shielding covers?
    High-temperature heat treatment optimizes the crystalline structure of the high magnetic permeability alloy. This significantly improves the magnetic shielding effectiveness, mechanical strength, and stability of the cover in complex electromagnetic environments.
    What is the difference between 1J79B and 1J85B materials?
    According to the YB/T5251-2013 standard, 1J85B generally exhibits higher initial and maximum magnetic permeability with lower coercivity compared to 1J79B, making it more effective for highly sensitive shielding applications, though 1J79B offers a higher saturation magnetic hardness.
