Neodymium Block Magnet - 76.2mm x 25.4mm x 6.35mm | N42 | Nickel Coating
Strong, versatile, and engineered for reliable performance, this Neodymium Block Magnet measures 76.2mm x 25.4mm x 6.35mm (3" x 1" x 1/4") and is manufactured from premium N42-grade rare earth neodymium. Combining a large rectangular surface area with impressive magnetic strength, this block magnet is ideal for industrial, engineering, workshop, manufacturing, and advanced DIY applications.
Finished with a durable Nickel (Ni) coating, this magnet features a smooth polished metallic appearance while helping protect against corrosion and surface wear. Magnetised through the 6.35mm thickness (axially magnetised), it delivers concentrated magnetic force across the broad flat surface for strong and dependable holding performance.
Its elongated rectangular profile makes this neodymium block magnet well suited to magnetic mounting systems, workshop fixtures, cabinetry, signage, engineering assemblies, fabrication projects, product design, and industrial holding applications. Whether used in manufacturing environments, prototyping, or custom magnetic solutions, this N42 block magnet offers professional-grade reliability and performance.

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.
