Product Overview
These 1" x 1/2" N52 Neodymium Disc Magnets are built for applications that demand maximum magnetic strength in a compact, easy-to-install form. The 1-inch diameter provides a broad magnetic contact surface, while the substantial 1/2-inch thickness creates an exceptionally deep magnetic field capable of producing approximately 61 pounds of pull force under ideal conditions. This combination makes them an excellent choice when maximum holding power is required without increasing the magnet's footprint.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these rare earth magnets offer the highest commercially available magnetic strength. They are ideal for industrial equipment, heavy-duty fixtures, woodworking, robotics, magnetic holding systems, product assemblies, and demanding engineering applications where reliability and performance are critical.
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 metallic finish.
What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a permanent magnet manufactured from NdFeB (Neodymium-Iron-Boron), the strongest commercially available magnetic material. Disc magnets provide exceptional magnetic strength in a compact circular design, making them one of the most versatile magnet styles available.
This magnet is magnetized through its thickness, placing the north and south poles on the two flat circular faces. Disc magnets are widely used in industrial equipment, magnetic fixtures, robotics, manufacturing, electronics, woodworking, magnetic closures, and custom engineering projects.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 1" x 1/2" N52 disc magnet delivers approximately 61 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 61 pounds of pull force under ideal testing conditions.
Is N52 stronger than N42 magnets?
Yes. N52 is the strongest commercially available neodymium magnet grade and delivers greater magnetic strength than N42 magnets of the same size.
Can this magnet rust?
The Nickel-Copper-Nickel triple-layer coating provides excellent protection against corrosion. If the coating becomes damaged and the magnet is exposed to moisture, corrosion may occur over time.
Can it be used outdoors?
Yes. However, additional sealing is recommended for long-term outdoor or marine applications.
