Product Overview
These 1.5" x 1/2" N52 Neodymium Disc Magnets are engineered for applications that demand exceptional holding power and maximum magnetic performance. The 1.5-inch diameter provides a large magnetic contact surface, while the 1/2-inch thickness creates a deep, concentrated magnetic field capable of generating approximately 80 pounds of pull force under ideal conditions. Their size and strength make them an excellent choice for industrial machinery, heavy-duty fixtures, magnetic assemblies, and demanding engineering applications.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these magnets deliver the highest commercially available magnetic strength. They outperform N50, N48, N45, N42, N40, N38, and N35 grades, making them ideal for applications where maximum holding force and long-term reliability are essential.
Each magnet features a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating that provides excellent resistance to corrosion, scratches, and chipping while maintaining a smooth, polished finish. Manufactured in ISO-certified facilities, these magnets offer consistent quality and dependable performance.
What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a permanent NdFeB (Neodymium-Iron-Boron) magnet made 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, and consumer products.
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 magnetic orientation provides maximum holding force against steel surfaces and makes disc magnets ideal for magnetic fixtures, tooling, machinery, product assemblies, and industrial equipment.
Neodymium magnets are also known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 1.5" x 1/2" N52 disc magnet provides approximately 80 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 80 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 significantly greater magnetic strength than N35 magnets of the same size.
Can it rust?
The Nickel-Copper-Nickel triple-layer coating helps protect 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.
