These magnets are nickel coated, weigh 2 grams and are 2.5mm high and 5mm in diameter. They have an individual pull force of 0.6210kg, Gauss4841, GradeN45 with the direction of magnetisation through height.

Although they are still mini magnets, these nickel coated Rare Earth disc magnets pack a punch. Weighing just two grams, each one has a pull force of more than half a kilogram - not bad for a disc that’s just 5 mm in diameter. Because of their superior strength, these Neodymium magnets are your ‘go to’ when you need strong hold but don’t need a big, bulky magnet to do the work. These deceptively powerful mini magnets can do the heavy lifting of magnets much larger than they are, but they can be discreetly hidden in applications where they would normally distract from the aesthetics. Neodymium Rare Earth disc magnets have a multitude of applications in the fashion and jewellery field, in hobby and craft, model-making and electronics and in any application that needs strong, discreet hold.

Production Flow Diagram
Demagnetization Curves
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.
