Neodymium Block Magnet - 50.8mm x 25.4mm x 3.175mm N52
Slim, powerful, and engineered for high-performance applications, this Neodymium Block Magnet measures 50.8mm x 25.4mm x 3.175mm (2" x 1" x 1/8") and is manufactured from premium N52-grade rare earth neodymium — one of the strongest commercially available magnet grades. Its low-profile rectangular design delivers exceptional magnetic holding power while remaining compact and easy to integrate into custom assemblies and mounting systems.
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 provides concentrated magnetic force across the large flat surface area for reliable holding and mounting performance.
Its wide rectangular profile makes this neodymium block magnet ideal for magnetic mounting systems, signage, cabinetry, engineering projects, workshop fixtures, retail displays, magnetic closures, fabrication work, and product design applications. Whether used in industrial manufacturing, prototyping, or advanced DIY projects, this N52 block magnet delivers professional-grade magnetic strength and versatility.

Please Note
Neodymium magnets are extremely powerful 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.
