These super slim Neodymium magnets have a pull Force of 0.1990kg, are nickel-coated, 4mm in diameter and 1 mm in height. Gauss3308, GradeN52, direction of magnetisation through height.
Neodymium Disc Magnets are the super heavyweights of the magnet world. Rare Earth disc magnets measuring just a millimetre in thickness are capable of mighty strength, but these nickel coated super strong disc magnets are so unobtrusive, they can perform a vast array of functions and applications - and you’d barely notice them. Because they are so slim and so strong, they are easily incorporated into all sorts of designs, from fashion and jewellery to home decor, DIY, craft, modelmaking, tools. electronics and automotive parts, in fact anything where two surfaces need to be held together. The magic ingredient is the Rare Earth Neodymium, which means they have amazing magnetic strength and hold.
The N52 Grade Neodymium material contained inside this magnet amplifies its strength to the maximum power level possible for a magnet this size. These strong, permanent Neodymium Disc magnets are easily glued into position on any non-metallic surface with epoxy glue so ferrous metal objects can be attached or removed quickly and easily Genius.

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.
