Wholesale 25*3mm Ndfeb Magnet | Fullzen

Short Description:

25×3mm NdFeB (Neodymium Iron Boron) magnet is a small, powerful disc-shaped magnet with a diameter of 25mm and a thickness of 3mm. It is known for its high magnetic strength and is widely used in applications that require compact size and strong magnetic properties.

Main Features:

Material:

Made from Neodymium Iron Boron (NdFeB) alloy, which is the strongest type of permanent magnet currently available.

Dimensions:

Diameter: 25mm (2.5cm).

Thickness: 3mm, making it a thin but powerful disc magnet.

Magnetic Strength:

The strength of a magnet depends on its grade. Common grades are N35, N42 or N52, with N52 being the strongest and capable of producing a strong magnetic field commensurate with its size.

The surface field strength of a 25×3mm N52 magnet is about 1.4 Tesla.

    FAQ

    How to make disc magnets?
    • Material Preparation: Mixing and melting NdFeB alloy.
    • Alloy Processing: Casting, crushing, milling, and sintering.
    • Shaping: Grinding, machining, and magnetizing.
    • Coating and Finishing: Applying protective coatings and quality checks.
    • Packaging: Packing for shipment.
    Are the manufacturing processes of disc magnets and cube magnets the same?

    Yes,The production process is the same, just the shape is different

    Why are disc magnets used?

    Disc magnets are used because their flat, circular shape combined with strong magnetic properties makes them ideal for a variety of applications where space is limited, and a strong magnetic field is needed. Here are key reasons why disc magnets are commonly used:

    1. Compact and Efficient Design

    • Space-Saving: Their flat shape allows them to fit into tight spaces, making them perfect for compact electronic devices and small mechanical systems.
    • Versatile: The shape is suitable for a wide range of applications, from holding and mounting to sensing and driving motors.

    2. Strong Magnetic Force

    • High Magnetic Strength: Especially in the case of neodymium disc magnets, they provide a very strong magnetic field relative to their size, making them effective in both industrial and consumer applications.

    3. Ease of Integration

    • Easy to Install: Their simple shape allows for easy installation and alignment in devices and systems.
    • Stable Performance: They maintain consistent performance in various environments, making them reliable components in many designs.

    4. Cost-Effective

    • Efficient Use of Material: The disc shape often requires less material to produce a strong magnetic field, reducing costs while maintaining performance.

    5. Wide Range of Applications

    • Electronics: Used in speakers, sensors, and other devices where a strong, focused magnetic field is needed.
    • Motors and Generators: Ideal for use in electric motors where space and power efficiency are critical.
    • Holding and Mounting: Commonly used for magnetic mounts, tool holders, and closures due to their strength and ease of use.

    Disc magnets are favored for their balance of size, strength, and versatility, making them a popular choice in both technical and everyday applications.
