Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
Black nickel-coated Neodymium disc magnet has a pull force of 0.2540kg, with a weight of 2 grams, a height of 1.58mm and a diameter of 3.18mm. Gauss5232, GradeN52 and direction of magnetisation through height.
These Neodymium discs may be tiny, but their small size is compensated for with a high-grade N52 magnetic material, and that’s a match made in heaven. It means these tiny disc magnets can occupy a smaller physical space while maintaining high magnetic effectiveness, important in any industry where size and weight reduction matters. By delivering improvements in performance, these Rare Earth magnets can help to reduce production costs and that bottom line is increasingly important as cost burdens increase. Neodymium magnets are used in almost every technological innovation, in industries such as robotics, aerospace, communications, automotive and the military.
Small disc magnets are often found in sensory devices and alarm systems where they provide reliable information and perform accurate duties continually, with little or no maintenance requirements.
This magnet stands out in our range because of its black nickel coating, which although it doesn’t change its performance, does have added appeal in some applications where a more reflective coating may have an impact on other functions.
WARNING!: ALL MAGNETIC PRODUCTS ARE A POTENTIAL SWALLOW HAZARD FOR CHILDREN AND VIGILANT PARENTAL SUPERVISION IS REQUIRED AT ALL TIMES.

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. 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.
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.
