Neodymium Block Magnet - 75mm x 25mm x 12.5mm | N45
Engineered for high-performance magnetic holding power, this Neodymium Block Magnet measures 75mm long x 25mm wide x 12.5mm thick and is manufactured from premium N45-grade rare earth neodymium. Combining a large surface area with impressive magnetic strength, this industrial-grade block magnet is ideal for demanding applications across workshops, manufacturing, engineering, fabrication, and DIY projects.
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 12.5mm thickness (axially magnetised), it delivers strong direct-contact holding performance on mild steel surfaces and other ferromagnetic materials.
Its rectangular profile makes it especially useful for magnetic mounting systems, heavy-duty holding fixtures, magnetic clamps, cabinetry, automation projects, and custom assemblies where a broad magnetic contact area is required. Whether you're designing industrial equipment or creating a powerful magnetic solution for your next project, this N45 neodymium block magnet offers dependable strength and professional-grade quality.

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.
