Product Overview
These 1" x 1/32" N52 Neodymium Disc Magnets deliver maximum magnetic performance in an ultra-thin profile. The 1-inch diameter provides a large magnetic contact area for reliable holding power, while the slim 1/32-inch thickness allows for nearly flush installations in applications where space is limited.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these magnets provide the highest commercially available magnetic strength in a lightweight, low-profile design. They are ideal for magnetic displays, woodworking, crafts, signage, product assemblies, lightweight fixtures, and custom DIY projects.
Each magnet is protected with 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.
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 excellent magnetic performance in a compact, flat design, making them one of the most versatile magnet shapes available.
This magnet is magnetized through its thickness, placing the north and south poles on the two flat circular faces. Its large diameter and ultra-thin profile make it especially well suited for magnetic displays, hidden closures, product packaging, educational projects, and precision assemblies.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 1" x 1/32" N52 disc magnet delivers over 3.2 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.
Although extremely thin, the large diameter provides excellent surface coverage and dependable holding power for lightweight applications.
Actual holding force depends on:
- Surface material
- Steel thickness
- Contact area
- Air gap
- Mounting method
- Environmental conditions
For maximum holding performance, use this magnet against a clean, flat steel surface.
Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be verified for your intended application.
