Magnetic Product Description:

This neodymium magnetic disc has a diameter of 10mm and a height of 2.5mm. It has a magnetic flux reading of 3063 Gauss and a pull force of 1.56 kilos. It is identified by the AMF magnet part number D-D10H2.5-N45.

Uses for our rare earth disc magnets:

This rare earth disc magnet is always a popular choice, particularly for those who are new to magnets. With modest dimensions, this circular magnet has a 1.56 kilogram holding power that is suitable for all sorts of home projects. As magnets can be quite brittle, it is always a good idea to match the appropriate thickness to the diameter. Too thin and the magnets can be difficult to handle, cracking and chipping with the impact of attachment.
Nickel plating is the most common type of Neodymium magnet coating, it provides a good resistance to corrosion in general atmospheric conditions. It is not a suitable coating for applications that will be exposed to high levels of moisture. If the magnets will be stored or situated in a humid environment, it is worth considering alternative coatings like Gold, Parylene-C or Teflon that provide greater levels of moisture protection.

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.
