Neodymium Disc Magnet 6.35mm x 3.175mm N45
Compact, versatile, and impressively strong for its size, this Neodymium Disc Magnet measures 6.35mm in diameter x 3.175mm in thickness and is manufactured from premium N45-grade rare earth neodymium for reliable magnetic performance across a wide range of applications. Its small disc profile makes it ideal for precision projects where strong magnetic force is required in a compact format.
Finished with a durable NiCuNi nickel coating, this magnet features a smooth polished metallic appearance while helping protect against corrosion and wear. Magnetised through the 3.175mm thickness (axially magnetised), it delivers concentrated magnetic force across the flat circular face for dependable holding and mounting performance.
Its compact size makes this neodymium disc magnet perfect for electronics, magnetic closures, crafts, model making, sensor systems, lightweight mounting applications, and custom fabrication projects. Whether you're prototyping products, building miniatures, or designing precision assemblies, this N45 disc magnet offers professional-grade strength and versatility.

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.
