This Neodymium Disc Magnet (19mm x 3.3mm) is a strong, compact rare earth magnet engineered for high performance in both commercial and everyday applications. Manufactured from N35 grade neodymium, it delivers dependable magnetic strength while maintaining a slim, low-profile design ideal for projects where space efficiency matters.
Protected by a durable NiCuNi triple-layer coating (Nickel–Copper–Nickel), this magnet offers excellent resistance to corrosion and wear while presenting a smooth, polished finish suitable for visible or high-touch applications.
Key Specifications
Product Code: 20019C
Dimensions: 19mm (Diameter) x 3.3mm (Thickness)
Weight: 7 grams
Magnet Grade: N35
Surface Gauss: 1985 Gauss
Pull Force: 3.85 kg
Magnetisation Direction: Axially magnetised (through the thickness)
Coating: NiCuNi (Nickel–Copper–Nickel)
Shape: Round Disc
Performance & Reliability
With a 3.85kg pull force, this magnet offers strong and stable holding capability, making it ideal for mounting, fastening, positioning and light industrial tasks. Its axial magnetisation ensures consistent magnetic performance across flat surfaces, giving it excellent versatility across a wide range of materials and environments.
Common Uses
Electronics, switches and sensor systems.
Prototyping, engineering and technical assemblies.
Magnetic closures for cabinetry, bags and retail packaging.
Home organisation, displays and signage.
DIY, hobby projects and educational activities.
Light mounting and holding applications.
Why Choose This Size?
The 19mm diameter provides a generous contact area for improved grip, while the 3.3mm thickness maintains a sleek profile. This balance of strength and size makes it a go-to magnet for professional installers, engineers, hobbyists and manufacturers seeking reliable magnetic performance in a compact disc design.

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.
