Neodymium Disc Magnet 18mm x 5mm N48
Strong, versatile, and compact, this Neodymium Disc Magnet measures 18mm in diameter x 5mm in thickness and is manufactured from premium N48-grade rare earth neodymium for exceptional magnetic performance. Combining a broad magnetic surface area with powerful holding strength, this disc magnet is ideal for industrial, commercial, workshop, and DIY applications.
Finished with a durable NiCuNi nickel coating, this magnet features a smooth polished metallic appearance while helping protect against corrosion and surface wear. Magnetised through the 5mm thickness (axially magnetised), it delivers concentrated magnetic force across the flat circular face for reliable and consistent holding power.
Its practical size and strong magnetic field make it suitable for magnetic mounting systems, signage, cabinetry, engineering projects, workshop fixtures, magnetic closures, product design, and fabrication work. Whether you're building custom magnetic assemblies or looking for dependable holding performance in a compact disc format, this N48 neodymium magnet offers professional-grade quality and strength.

Please Note
Neodymium magnets are extremely strong for their size and should be handled carefully. Avoid allowing magnets to snap together forcefully, as they may chip or crack upon impact. Keep away from children, pacemakers, electronic devices, and magnetic storage media.

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.
