Neodymium Disc Magnets N52 – Magnets Suppliers | Fullzen

Short Description:

N52 Neodymium Disc Magnets are ideal for customers who require a disc-shaped magnet that is versatile, but delivers more energy than the popular N42 grade Neodymium magnets. At Fullzen Technology, we offer N52 disc magnets in different sizes and strengths, as well as N42 disc magnets, which means you don’t have to trade off specific design requirements for size for strength. All N52 disc magnets are plated to prevent chipping and corrosion. Fullzen’s magnets have low weight loss and maintain high performance throughout their lifetime.

    Neodymium Disc Magnets N52

    N52 Neodymium Magnets are ideal for delicate applications that include:

    – Mounting tiny tracking devices to vehicles or other equipment.

    – Magnetic stirrers that are used by scientists to protect mixtures from contamination.

    – Magnetic switches such as those used in alarm systems.

    – Magnetic sensors such as those in anti-lock braking systems.


    What is the best grade of neodymium magnets?

    The best grade of neodymium magnets depends on the specific application and requirements. Neodymium magnets come in various grades, ranging from N35 to N52 (with N52 being the highest). The higher the grade number, the stronger the magnet's magnetic field will be. However, higher-grade magnets are also more brittle and prone to breakage.For general use, N42 or N52 neodymium magnets are considered the best grades due to their strong magnetic fields. These magnets are commonly used in industrial and commercial applications where a high level of magnetic force is required.

    Why are neodymium magnets so expensive?

    Neodymium magnets are relatively expensive compared to other types of magnets due to a few key reasons:

    1. Raw materials: Neodymium magnets are made from a combination of neodymium, iron, and boron (NdFeB). Neodymium is a rare-earth element, and the extraction and refining process is complex and costly. The price of neodymium fluctuates due to supply and demand factors, which can impact the cost of neodymium magnets.
    2. Manufacturing process: Producing neodymium magnets involves multiple steps, including mixing the raw materials, pressing the mixture into shapes, sintering (heating) the formed magnets, and finally, magnetizing them. The entire process requires specialized equipment and expertise, which adds to the production costs.
    3. High magnetic performance: Neodymium magnets have exceptional magnetic properties, offering high strength and powerful magnetic fields. This means they can generate strong attractive forces while being relatively small and lightweight compared to other magnets. The ability to create such powerful magnets comes with a premium price tag.
    4. Limited resources: Neodymium is not as abundant as other elements, which makes it a limited resource. The limited supply and high demand for neodymium magnets contribute to their higher cost.

    Overall, the combination of raw materials, manufacturing processes, magnetic performance, and limited resources contribute to the higher expense of neodymium magnets compared to other magnet types.

    Do neodymium magnets break easily?

    Neodymium magnets are known for their strength and durability. However, they are also relatively brittle, meaning they can break or chip if subjected to excessive force or impact. This is particularly true for smaller, thinner magnets, which are more susceptible to damage.To ensure the longevity and integrity of neodymium magnets, it is important to handle them with care and avoid situations where they might collide with hard surfaces or other magnets. Additionally, protective coatings or enclosures can be used to minimize the risk of breakage and to provide additional protection against corrosion.

    Can neodymium magnet rust?

    Yes, neodymium magnets can rust if they are not properly coated or protected. Neodymium magnets are made of a combination of neodymium, iron, and boron, and the iron content is particularly susceptible to corrosion. When exposed to moisture or humid environments, the iron in the magnet can oxidize and eventually rust.To prevent rusting, neodymium magnets are often coated with a protective layer such as nickel, zinc, or epoxy. This protective coating acts as a barrier between the magnet and the surrounding environment, preventing direct contact with moisture and reducing the risk of rusting. However, if the coating is damaged or compromised, the magnet can still be vulnerable to rust. It's important to keep neodymium magnets dry and protected to maintain their longevity.
