Neodymium Disc Magnet 25.4mm x 3.175mm N42
Strong, slim, and highly versatile, this Neodymium Disc Magnet measures 25.4mm in diameter x 3.175mm in thickness (1" x 1/8") and is manufactured from premium N42-grade rare earth neodymium for reliable magnetic performance across a wide range of industrial, commercial, and DIY applications. Its low-profile disc design provides excellent holding power while remaining compact and easy to integrate into custom projects and assemblies.
Finished with a durable NiCuNi nickel coating, this magnet features a smooth polished silver 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.
With its larger 25.4mm diameter, this neodymium disc magnet offers excellent surface contact, making it ideal for magnetic mounting systems, signage, cabinetry, retail displays, packaging solutions, engineering projects, and magnetic closures. Whether you're prototyping products, fabricating custom solutions, or working on workshop and craft projects, this N42 disc magnet provides professional-grade quality and versatility.

Please Note
Neodymium magnets are extremely strong for their size and should be handled carefully. Magnets may snap together unexpectedly and can 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.
