This Neodymium Disc Magnet (27mm x 3.4mm) is a robust and versatile rare earth magnet engineered for applications requiring strong magnetic grip and reliable long-term performance. Manufactured from N35 grade neodymium, it provides powerful and consistent magnetic strength in a practical mid-sized disc format.
Featuring a premium NiCuNi triple-layer coating (Nickel–Copper–Nickel), this magnet offers superior corrosion resistance and a smooth, polished finish suitable for industrial, commercial and home applications.
Key Specifications
Product Code: 20003
Dimensions: 27mm (Diameter) x 3.4mm (Thickness)
Weight: 15 grams
Magnet Grade: N35
Surface Gauss: 1478 Gauss
Pull Force: 5.66 kg
Magnetisation Direction: Axially magnetised (through the thickness)
Coating: NiCuNi (Nickel–Copper–Nickel)
Shape: Round Disc Magnet
Strength & Performance
Delivering a 5.66kg pull force, this magnet strikes an impressive balance between size and strength. Its axial magnetisation ensures dependable, even magnetic performance across flat ferrous surfaces, making it ideal for medium to heavy-duty holding, fastening and mounting tasks.
Common Applications
Industrial fixtures and assemblies.
Electronics, sensor housings and technical components.
Magnetic closures for cabinetry, packaging and product design.
Retail displays, signage and POS systems.
Home organisation, workshop storage and DIY projects.
Prototyping, engineering and educational use.
Why Choose This Magnet?
The 27mm diameter provides increased contact area for improved grip, while the 3.4mm thickness maintains a streamlined, easily integrated profile. This combination makes it a popular choice among manufacturers, installers, engineers and hobbyists seeking strong, reliable magnetic performance in a compact disc format.

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.
