Neodymium Disc Magnet - 18mm x 6mm | N48
Magnetic Product Description:
This neodymium magnetic disc has a diameter of 18mm and a height of 6mm. It has a magnetic flux reading of 3938 Gauss and a pull force of 8.80 kilos. It is identified by the AMF magnet part number D-D18H6-N48.
Uses for our Rare Earth Disc Magnets:
Neodymium magnets are the magnet of choice when heavy-duty holding power is required. They have superior holding ability compared to other discs made with other magnetic materials of the same dimensions. Although they require a higher initial outlay to purchase compared to other magnetic materials, this is often easily compensated for by their superior holding performance or their long term durability. Strong, round Neodymium magnets are used in a wide range of applications that can include simple holding requirements around the home or performing high-tech operations inside state of the art electronic devices.
Electric motors use permanent Neodymium magnets to transform electric currents into rotational movement. This important and unique ability performed by a magnetic field is also harnessed to transform sound waves into the amplified electrical signals and is the basis of how modern microphones and speakers operate. The flat, circular, disc shape of these Neodymium magnets is an important factor in how this transformation occurs.

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.
