This Neodymium Disc Magnet (18mm diameter x 10mm height) is a high-performance rare earth magnet designed for applications that demand serious holding power in a compact form. Manufactured from N42 grade neodymium, it delivers an impressive pull force of 10.44 kilograms, making it ideal for industrial, commercial, and DIY uses where reliability matters.
With a surface field of approximately 4,902 gauss, this magnet provides strong, consistent magnetic performance through its height (axially magnetised). The durable NiCuNi (Nickel–Copper–Nickel) coating offers excellent corrosion resistance while giving the magnet a smooth, professional silver finish suitable for exposed or visible installations.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.
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.
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics 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.
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.
