Quick Answers

Question Answer
How strong is this magnet? Approximately 270 lbs of pull force under ideal conditions.
What is this magnet made of? NdFeB (Neodymium-Iron-Boron) rare earth material.
Is this stronger than N35 magnets? Yes. N52 is the highest commercially available neodymium grade and delivers substantially greater magnetic strength than N50, N48, N45, N42, N40, N38, and N35 magnets.
Can it be used outdoors? Yes, but additional sealing is recommended for long-term outdoor or marine environments.
What is it commonly used for? Heavy-duty industrial fixtures, magnetic separators, lifting devices, robotics, manufacturing equipment, engineering projects, scientific research, and high-performance magnetic assemblies.

Product Overview

These 2" x 1" N52 Neodymium Disc Magnets are among the most powerful permanent magnets available for industrial and commercial applications. The 2-inch diameter provides an expansive magnetic contact surface, while the 1-inch thickness generates an exceptionally deep magnetic field capable of producing approximately 270 pounds of pull force under ideal conditions. They are engineered for applications where maximum holding strength and reliability are essential.

Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these magnets represent the highest commercially available neodymium grade. They provide significantly greater magnetic energy than N50, N48, N45, N42, N40, N38, and N35 magnets, making them ideal for heavy-duty industrial tooling, automation equipment, magnetic separators, scientific instruments, robotics, engineering prototypes, and demanding manufacturing environments.

Each magnet is protected with a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing outstanding resistance to corrosion, scratches, and chipping while maintaining a smooth, polished finish. Manufactured in ISO-certified facilities, these magnets deliver exceptional consistency, durability, and long-term performance.

What Is a Neodymium Disc Magnet?

A neodymium disc magnet is a permanent NdFeB (Neodymium-Iron-Boron) magnet manufactured from an alloy of neodymium, iron, and boron. Neodymium magnets are the strongest commercially available permanent magnets and are widely used throughout manufacturing, robotics, engineering, automation, scientific research, electric motors, generators, and industrial machinery.

This magnet is magnetized through its 1-inch thickness (axially magnetized), placing the north and south poles on the two flat circular faces. This orientation produces maximum holding power against ferromagnetic surfaces, making disc magnets ideal for heavy-duty magnetic fixtures, industrial assemblies, and precision positioning systems.

Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.

How Strong Is This Magnet?

This 2" x 1" N52 disc magnet delivers approximately 270 pounds of pull force under ideal laboratory conditions using a thick, clean steel plate.

Actual holding force depends on several factors, including:

  • Surface material
  • Steel thickness
  • Contact area
  • Air gap
  • Mounting method
  • Environmental conditions

Because of its extremely high magnetic strength, this magnet should be handled carefully to avoid pinching injuries or damage to nearby objects.

Note: Pull force values are measured under ideal laboratory conditions. Actual performance should always be verified in your intended application.

Common Questions About This Magnet

What is the pull force?

This magnet provides approximately 270 pounds of pull force under ideal testing conditions.

Is N52 stronger than N35 magnets?

Yes. N52 is the highest commercially available neodymium magnet grade and delivers substantially greater magnetic strength than N35 magnets of the same dimensions.

Can it rust?

The Nickel-Copper-Nickel triple-layer coating provides excellent protection against corrosion. If the coating becomes damaged and moisture reaches the magnet, corrosion may eventually occur.

Can it be used outdoors?

Yes. However, additional sealing is recommended for prolonged outdoor exposure, marine environments, or high-humidity conditions.

What direction is it magnetized?

This magnet is magnetized through its 1-inch thickness (axially magnetized), with the north and south poles located on the two flat circular faces.
