Neodymium Disc Magnet – 25.4mm x 12.7mm | N38
Deliver exceptional magnetic performance with this Neodymium Disc Magnet, measuring 25.4mm (1") in diameter x 12.7mm (½") thick. Manufactured from premium N38-grade NdFeB (Neodymium Iron Boron) rare earth magnetic material, this powerful permanent magnet is designed for demanding industrial, engineering, manufacturing, automation, and research applications where reliable holding force is essential.
Neodymium magnets are the strongest commercially available permanent magnets, providing significantly greater magnetic strength than ferrite, Alnico, or samarium cobalt magnets of similar dimensions. The combination of a 25.4mm diameter and substantial 12.7mm thickness provides high magnetic energy and an excellent contact surface, making this magnet ideal for heavy-duty holding, clamping, positioning, mounting, and magnetic separation applications.
This disc magnet is axially magnetised, meaning the magnetic poles are located on the two flat 25.4mm circular faces, delivering maximum face-to-face holding performance against ferrous steel surfaces or when incorporated into custom magnetic assemblies.
Protected by a durable nickel-copper-nickel (Ni-Cu-Ni) coating, this magnet offers outstanding resistance to corrosion, oxidation, and everyday wear while maintaining a smooth, polished finish.

Why Choose an N38 Neodymium Disc Magnet?
The 25.4mm x 12.7mm N38 Neodymium Disc Magnet provides an outstanding balance of size, strength, and versatility. Its thicker profile delivers increased magnetic energy, while the 25.4mm diameter offers a generous contact area for secure holding and positioning. It is an excellent choice for magnetic fixtures, clamping systems, automation equipment, and custom-engineered products where dependable, long-lasting performance is required.
Please Note
This is a high-strength rare earth magnet and should be handled carefully to avoid pinch injuries or damage caused by magnets snapping together. Holding performance is achieved under ideal conditions using a clean, flat, thick ferrous steel surface with full face-to-face contact. Actual magnetic strength will vary depending on the steel thickness, surface finish, air gap, and application.
Keep away from children, pacemakers, implanted medical devices, sensitive electronic equipment, magnetic storage media, and precision instruments. Avoid drilling, machining, excessive heat exposure, or heavy impacts, as these may permanently damage the magnet or reduce its magnetic performance.

Surface Treatment
The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Range and Tolerance
Magnets are readily available in Blocks, Discs, Cylinders & Rings. We specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Magnetic Properties
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
