Product Overview
These 2" x 1/2" N52 Neodymium Disc Magnets deliver exceptional holding power for the most demanding industrial and commercial applications. The 2-inch diameter provides a large magnetic contact area, while the 1/2-inch thickness generates a deep, powerful magnetic field capable of producing approximately 135 pounds of pull force under ideal conditions. Their combination of size, strength, and reliability makes them an excellent choice for applications requiring maximum magnetic performance.
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 magnetic fixtures, industrial tooling, robotics, automation systems, magnetic separators, and engineering applications where superior holding power is essential.
Each magnet is protected by a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, offering excellent resistance to corrosion, scratches, and chipping while maintaining a smooth, polished finish. Manufactured in ISO-certified facilities, these magnets deliver consistent quality, exceptional durability, and dependable 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, engineering, robotics, automation, scientific equipment, motors, generators, and industrial machinery.
This magnet is magnetized through its 1/2-inch thickness (axially magnetized), placing the north and south poles on the two flat circular faces. This orientation maximizes holding force against steel surfaces, making disc magnets ideal for magnetic fixtures, product assemblies, tooling, and heavy-duty industrial applications.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 2" x 1/2" N52 disc magnet delivers approximately 135 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.
Actual holding force depends on several factors, including:
- Surface material
- Steel thickness
- Contact area
- Air gap
- Mounting method
- Environmental conditions
For maximum holding performance, use this magnet against a clean, flat, thick steel surface.
Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be verified for your intended application.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 135 pounds of pull force under ideal testing conditions.
Is N52 stronger than N35 magnets?
Yes. N52 is the strongest commercially available neodymium magnet grade and delivers significantly 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 occur over time.
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 1/2-inch thickness (axially magnetized), with the north and south poles located on the two flat circular faces.
