Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 2.5 lbs 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 size. |
| Can it be used outdoors? |
Yes. The Nickel-Copper-Nickel triple-layer coating provides excellent corrosion resistance. Additional sealing is recommended for prolonged outdoor or marine exposure. |
| What is it commonly used for? |
Bottle cap magnets, magnetic crafts, closures, woodworking, office organization, electronics, models, and DIY projects. |
Product Overview
The N52 Neodymium Disc Magnet 5/16" x 1/16" delivers exceptional magnetic strength in a compact, ultra-thin design. With a 5/16-inch diameter and a slim 1/16-inch profile, this rare earth magnet offers excellent surface contact while remaining easy to conceal inside projects where space is limited.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these disc magnets provide the highest magnetic strength available in standard neodymium magnets. Their impressive holding power makes them ideal for woodworking, electronics, magnetic closures, product assembly, bottle cap crafts, office organization, and precision DIY applications where reliable performance is essential.
Each magnet features a durable Nickel-Copper-Nickel triple-layer coating that provides outstanding resistance to corrosion, oxidation, and everyday wear. Compared to standard epoxy-coated magnets, the triple-layer nickel finish offers significantly greater durability and improved resistance to cracking and chipping, helping preserve long-term 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 provide exceptional magnetic strength while remaining compact and lightweight, making them one of the most versatile permanent magnets available.
Disc magnets are commonly used in woodworking, manufacturing, electronics, crafts, retail displays, magnetic closures, sensors, and embedded assemblies because they provide excellent holding power while maintaining a low-profile design.
How Strong Is This Magnet?
This N52 neodymium disc magnet produces approximately 2.5 pounds of pull force under ideal conditions against a thick, flat steel surface. Although only 1/16 inch thick, its 5/16-inch diameter provides excellent surface contact, resulting in reliable holding performance across a wide variety of light- and medium-duty applications.
The premium N52 magnetic grade delivers the highest magnetic energy available in standard neodymium magnets, making this an outstanding choice whenever maximum strength is required in a compact disc magnet.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 2.5 pounds 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 superior protection against moisture, oxidation, cracking, and chipping compared to standard epoxy-coated magnets.
Can it be used outdoors?
Yes. The triple-layer nickel coating provides excellent corrosion resistance. For continuous outdoor or marine applications, additional sealing 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.
Do you offer bulk discounts?
Yes. Super Magnet Store offers competitive wholesale pricing and quantity discounts for manufacturers, distributors, schools, retailers, crafters, and OEM customers.
