Neodymium Disc Magnet 8mm x 5mm N45
Compact, powerful, and versatile, this Neodymium Disc Magnet measures 8mm in diameter x 5mm in thickness and is manufactured from premium N45-grade rare earth neodymium for strong and reliable magnetic performance. Its thicker disc profile delivers impressive holding strength relative to its size, making it ideal for precision applications across engineering, electronics, workshops, crafts, and DIY projects.
Finished with a durable NiCuNi nickel coating, this magnet features a smooth polished silver appearance while helping protect against corrosion and surface wear. Magnetised through the 5mm thickness (axially magnetised), it provides concentrated magnetic force across the flat circular face for dependable holding and mounting performance.
Its compact dimensions make this neodymium disc magnet well suited to magnetic closures, sensor systems, model making, cabinetry, lightweight mounting applications, product design, and custom magnetic assemblies. Whether you're prototyping components or creating detailed fabrication projects, this N45 disc magnet offers professional-grade strength in a compact format.

Please Note
Neodymium magnets are extremely strong for their size and should be handled carefully. Small magnets can present a swallowing hazard and must be kept away from children. Avoid allowing magnets to snap together unexpectedly, as they may chip or crack upon impact.

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.
