Neodymium Disc Magnet 12.7mm x 3.175mm N50
Compact yet extremely powerful, this Neodymium Disc Magnet measures 12.7mm in diameter x 3.175mm in height and is manufactured from premium N50-grade rare earth neodymium for outstanding magnetic strength and reliability. Its slim disc profile makes it ideal for applications requiring strong holding power in a low-profile design.
Finished with a durable NiCuNi nickel coating, this magnet features a smooth polished metallic appearance while providing added resistance against corrosion and wear. Magnetised through the 3.175mm thickness (axially magnetised), it delivers concentrated magnetic performance across its flat circular surface.
This versatile neodymium disc magnet is commonly used in engineering, electronics, magnetic closures, retail displays, crafts, model making, cabinetry, packaging, and custom fabrication projects. Its larger 12.7mm diameter provides excellent surface contact and dependable holding strength for a wide range of commercial and DIY applications.

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.
