Neodymium Disc Magnet – 18mm x 1mm | N35
The Neodymium Disc Magnet 18mm x 1mm | N35 is an ultra-thin rare earth permanent magnet designed for applications where a low-profile magnetic solution is required without compromising holding performance. Manufactured from premium N35-grade Neodymium Iron Boron (NdFeB), this precision disc magnet measures 18mm in diameter and just 1mm thick, making it ideal for signage, displays, crafts, packaging, electronics, product design, and light-duty industrial applications.
Its slim profile allows it to be easily concealed behind materials while still providing strong magnetic attraction for its size. The magnet is axially magnetised, meaning the north and south poles are located on the two flat circular faces, ensuring maximum holding force when placed against a ferrous steel surface or paired with another magnet.
Finished with a durable nickel-copper-nickel (Ni-Cu-Ni) coating, this magnet offers excellent resistance to corrosion, oxidation, and everyday wear, while maintaining a bright, polished appearance.
The 18mm x 1mm N35 Neodymium Disc Magnet is a popular choice for applications requiring a discreet, lightweight, and reliable magnetic solution where installation space is limited.

Why Choose an 18mm x 1mm N35 Neodymium Disc Magnet?
The 18mm x 1mm N35 Neodymium Disc Magnet is designed for applications where minimal thickness is just as important as magnetic performance. Its wide diameter provides a generous magnetic contact area, while the ultra-thin 1mm profile allows it to be hidden behind thin materials such as timber, acrylic, cardboard, plastic, or fabric.
Compared with ferrite magnets of similar dimensions, this neodymium magnet delivers significantly greater magnetic strength, making it an excellent choice for magnetic closures, display systems, packaging, promotional products, and lightweight engineering applications where appearance and space-saving design are important.

Please Note
This is a high-strength rare earth magnet and should be handled with care. Although only 1mm thick, it is surprisingly powerful for its size and can snap together unexpectedly with other magnets or steel objects, potentially causing pinch injuries or damage to the magnet.
Maximum holding force is measured under ideal conditions using a clean, flat, thick mild steel surface with full face-to-face contact. Actual magnetic performance will vary depending on the steel thickness, air gap, surface finish, mounting arrangement, and operating environment.
Keep away from children, as small magnets can present a serious swallowing hazard. Keep away from pacemakers, implanted medical devices, sensitive electronic equipment, and magnetic storage media. Do not drill, machine, or strike the magnet, as neodymium is hard but brittle and may crack or shatter under excessive mechanical stress. For maximum service life, avoid prolonged exposure to corrosive environments, excessive impact, or temperatures beyond the recommended operating range for standard N35 neodymium magnets.

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.
