Neodymium Block Magnet – 36mm x 3.4mm x 2.6mm | N52
The Neodymium Block Magnet – 36mm x 3.4mm x 2.6mm | N52 is an ultra-high-performance rare earth permanent magnet designed for applications requiring exceptional magnetic strength in a slim, low-profile rectangular package. Manufactured from premium N52 grade neodymium iron boron (NdFeB), this magnet delivers one of the highest magnetic energy ratings available in a standard neodymium grade, making it ideal for precision engineering, product manufacturing, automation, and industrial applications.
Measuring 36mm long, 3.4mm wide, and 2.6mm thick, this narrow block magnet is perfect for installations where space is restricted but maximum magnetic performance is required. Its slim profile makes it easy to embed into timber, aluminium, plastics, composite materials, and precision-machined components, making it suitable for magnetic closures, fixtures, positioning systems, sensors, display products, and custom OEM assemblies.
The magnet is axially magnetised through its 2.6mm thickness, placing the north and south poles on the two 36mm x 3.4mm flat faces. This magnetisation direction maximises the magnetic contact area, providing strong face-to-face attraction and excellent holding performance against suitable ferrous surfaces.
Protected by a durable nickel-copper-nickel (Ni-Cu-Ni) triple-layer coating, the magnet features a polished silver finish that helps resist corrosion and everyday wear while maintaining long-term magnetic performance.

Why Choose an N52 Neodymium Block Magnet?
The N52 grade is one of the strongest commercially available standard grades of neodymium magnet, offering exceptional magnetic energy in a compact package. This allows designers and engineers to maximise holding power while minimising the size and weight of their assemblies.
The 36mm x 3.4mm x 2.6mm profile is particularly well suited to applications requiring a long, narrow magnetic strip with minimal installation depth. It can be recessed into slim channels, narrow frames, custom housings, and lightweight products while delivering powerful magnetic performance.
Because the magnet is magnetised through its 2.6mm thickness, the magnetic field is concentrated across the two largest faces. This provides excellent contact with steel surfaces and makes the magnet ideal for magnetic mounting, holding, alignment, latching, and precision positioning applications.

Please Note
Neodymium magnets are extremely powerful for their size and should always be handled with care. This N52 block magnet can attract nearby steel objects or other magnets unexpectedly, creating pinch hazards and potentially causing the magnet to chip or crack if allowed to collide.
Actual holding force depends on the thickness, grade, finish, and condition of the mating steel surface. Air gaps, paint, coatings, uneven contact, elevated temperatures, and sideways or peeling forces can significantly reduce magnetic performance.
Neodymium magnets are hard but brittle. Do not drill, cut, machine, weld, or subject the magnet to heavy impacts, as this may damage the magnet and its protective coating.
Keep away from children, pacemakers, medical implants, magnetic storage media, credit cards, and sensitive electronic equipment that may be affected by strong magnetic fields.

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.
