Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 4.8 lbs or more 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 standard neodymium grade and delivers substantially greater magnetic strength than N35, N38, N40, N42, and N48 magnets of the same dimensions. |
| Can it be used outdoors? |
Yes. The Nickel-Copper-Nickel triple-layer coating provides excellent corrosion resistance. Additional sealing is recommended for continuous outdoor or marine environments. |
| What is it commonly used for? |
Magnetic closures, woodworking, bottle cap magnets, displays, electronics, organization, crafts, and DIY projects. |
Product Overview
The N52 Neodymium Disc Magnet 5/16" x 1/8" is engineered to deliver maximum magnetic performance in a compact yet powerful package. With a 5/16-inch diameter and a thicker 1/8-inch profile, this rare earth disc magnet provides exceptional surface contact and a deeper magnetic field than thinner discs, resulting in a stronger, more secure hold across a wide variety of applications.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these magnets deliver the highest magnetic strength available in standard neodymium magnets. Their superior holding power makes them ideal for woodworking, magnetic closures, electronics, product assembly, displays, bottle cap magnets, fixtures, and custom DIY projects where reliable performance is essential.
Each magnet is NdFeB Patent Licensed and protected by a durable Nickel-Copper-Nickel triple-layer coating that provides outstanding resistance to corrosion, oxidation, and everyday wear while maintaining a smooth, polished appearance. Whether used in professional manufacturing or home workshops, these magnets provide dependable, long-lasting performance.
What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a circular permanent magnet manufactured from neodymium, iron, and boron (NdFeB). These rare earth magnets offer exceptional magnetic strength while maintaining compact dimensions, making them one of the most versatile permanent magnets available.
Disc magnets are commonly used throughout manufacturing, woodworking, electronics, retail displays, magnetic closures, crafts, sensors, and embedded assemblies because they provide excellent holding power while remaining easy to install and conceal.
How Strong Is This Magnet?
This N52 neodymium disc magnet generates approximately 4.8 pounds or more of pull force under ideal conditions against a thick, flat steel surface. Its 5/16-inch diameter provides excellent contact area, while the 1/8-inch thickness creates a deeper magnetic field that delivers stronger holding performance than thinner magnets.
The premium N52 magnetic grade provides the highest magnetic energy available in standard neodymium magnets, making this disc magnet an excellent choice whenever maximum strength is required in a compact size.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 4.8 pounds or more of pull force under ideal conditions against a thick steel surface.
Is N52 stronger than N35?
Yes. N52 is the strongest standard neodymium magnet grade and provides substantially greater magnetic strength than N35 magnets of the same dimensions.
Can it rust?
Like all neodymium magnets, the core material can corrode if exposed. The Nickel-Copper-Nickel triple-layer coating provides excellent protection against moisture, oxidation, and everyday wear.
Can it be used outdoors?
Yes. The triple-layer nickel coating offers excellent corrosion resistance. For continuous outdoor or marine applications, an additional protective sealant is recommended.
What direction is it magnetized?
This magnet is magnetized through its thickness, with the north and south poles located on the two flat circular faces.
