N52 Neodymium Magnet Disc

N52 Neodymium Magnet Disc

The N52 Neodymium Magnet Disc is a high-grade rare earth magnet, known for its exceptional strength and performance. With the N52 grade, the highest available for neodymium magnets, it provides a powerful magnetic field ideal for demanding applications. This disc-shaped magnet offers reliable holding force in a compact form, making it perfect for use in precision equipment, sensors, motors, magnetic locks, and other industrial applications. Its strong magnetic properties also make it popular in scientific experiments, prototyping, and various DIY projects. Despite its small size, the N52 magnet disc ensures excellent durability and efficiency, meeting the needs of both commercial and personal uses.

 Product Details 

What grades & shapes are available for neodymium magnets?

Grades N35, N38, N40, N42, N48, N50, and N52 ( M, H, SH, UH, EH, AH series ) are available for all shapes & sizes of NdFeB magnets.

  Magnetization Direction 

Common direction of magnetization showed in picture bellow: 

• Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametricall.
• Rectangle magnets can be magnetized through Thickness, Length or Width.
• Arc shape magnets can be magnetized Diametrically, through Width or Thickness.

Axially Magnetized                    Diametrically Magnetized                    Multi-poles Axially                     Multi-poles Diametrically

 Grade & Coating 

Support all magnet plating , like Ni-Cu-Ni, Zn, Epoxy , Gold,  Silver etc.

• Neodymium magnets are made of Neodymium, Iron and Boron.  If left to the elements, the iron in magnet will rust.

To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated.

• There are a variety of options for coatings, but nickel is the most common and usually preferred. 

Our nickel plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes  magnets much more durable than the more common single nickel plated magnets.

• Other options of coating are zinc, tin, copper, epoxy,silver and gold.

 Application 

The N52 Neodymium Magnet Disc is widely used across various industries due to its exceptionally high magnetic strength and compact size. Some common applications include:

• Electronics: Used in speakers, microphones, and sensors to improve sound quality and signal processing.
• Motors and Generators: Incorporated into high-efficiency motors, especially in electric vehicles, drones, and robotics.
• Medical Devices: Applied in magnetic therapy, MRI machines, and surgical tools requiring precise magnetic control.
• Magnetic Fastening Systems: Ideal for closures in cabinets, wallets, and DIY projects where a strong and compact magnet is needed.
• Magnetic Separation: Used in industrial settings to remove metal contaminants from products in food processing and recycling.

These N52 magnets, known for having one of the highest energy densities available, are preferred where performance, reliability, and space-saving design are crucial.
