N52H NdFeB Magnet Block

N52H NdFeB Magnet Block

The N52H NdFeB Magnet Block is a premium-grade permanent magnet engineered for demanding industrial, technological, and commercial applications. Utilizing advanced neodymium iron boron (NdFeB) material with an N52H energy grade, this magnet block delivers exceptional magnetic strength (up to 52 MGOe) and high coercivity, ensuring superior performance even in high-temperature environments (rated up to 120°C).

 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.

 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 

Precision-machined into rectangular or square blocks, it features a robust multi-layer coating (nickel-copper-nickel or epoxy) for enhanced corrosion resistance, making it ideal for harsh operating conditions. With its ultra-high remanence and magnetic stability, this magnet is widely used in:

• Motors & Generators: Optimizes efficiency in electric vehicles, wind turbines, and robotics.
• Medical Devices: Powers MRI systems, surgical tools, and diagnostic equipment.
• Automotive Systems: Enhances sensors, actuators, and hybrid/electric drivetrains.
• Industrial Automation: Critical for magnetic separators, lifting systems, and precision machinery.
