Neodymium Disc Magnet – 25mm x 8mm | N35
Powerful, compact, and precision-engineered, this Neodymium Disc Magnet measures 25mm in diameter x 8mm thick and is manufactured from premium N35-grade NdFeB (Neodymium Iron Boron) rare earth magnetic material. Designed for dependable magnetic performance, this permanent magnet is ideal for engineering, manufacturing, automation, product assembly, woodworking, signage, scientific applications, and heavy-duty DIY projects.
Neodymium magnets are the strongest commercially available permanent magnets, providing significantly greater holding power than ferrite, Alnico, or samarium cobalt magnets of comparable size. The combination of a 25mm diameter and 8mm thickness delivers an excellent balance of magnetic contact area and magnetic energy, making this magnet suitable for demanding holding, mounting, positioning, and clamping applications.
This disc magnet is axially magnetised, meaning the magnetic poles are located on the two flat 25mm diameter faces. This orientation provides maximum face-to-face holding force when used against a ferrous steel surface or paired with another magnet.
The magnet is finished with a durable nickel-copper-nickel (Ni-Cu-Ni) coating, providing excellent resistance to corrosion, oxidation, and everyday wear while maintaining a smooth, polished finish.

Why Choose an N35 Neodymium Disc Magnet?
The 25mm x 8mm N35 Neodymium Disc Magnet offers an excellent balance of strength, durability, and value. Its thicker profile provides increased magnetic energy compared to thinner disc magnets, while the 25mm diameter creates a generous contact area for secure holding. This makes it an excellent choice for magnetic fixtures, clamping systems, mounting applications, automation equipment, and custom engineering projects.
Please Note
This is a high-strength rare earth magnet and should be handled carefully to prevent 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, and magnetic storage media. 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.
