Neodymium Disc Magnet - 8mm x 3mm | N52

Magnetic Product Description:

This neodymium magnetic disc has a diameter of 8mm and a height of 3mm. It has a magnetic flux reading of 4440 Gauss and a pull force of 1.76 kilos. It is identified by the AMF magnet part number D-D8H3-N52.

Uses for our small Rare Earth Disc Magnets:

Small Neodymium disc magnets are generally used to bond lightweight material, such as plastic, cardboard or cloth, with metal, steel and other surfaces that have some degree of ferrous content. Circular shape magnets made from heavy-duty Neodymium material have incredible holding ability for their size and weight. Strong, Rare-earth magnetic products with permanent magnetism have in recent decades provided important attachment alternatives and greatly contributed to changing the perception of how bonding is performed for both small and large scale product designers and manufacturers.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

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.
