Magnetic Product Description:

This neodymium magnetic disc has a diameter of 6.35mm and a height of 3.17mm. It has a magnetic flux reading of 4842 Gauss and a pull force of 1.1 kilos. It is identified by the AMF magnet part number D-D6.35H3.175-N45.

Uses for our rare earth disc magnets:

The thin profile of this Neodymium disc magnet makes it an appropriate choice for attachment and holding applications. The reduced thickness of this circle magnet means it is unlikely to be accidentally dislodged by a passerby knocking it out of position, providing a secure and reliable hold. Popular as a component in electronic devices, this small magnet enables magnetic power to be utilised within the product without the need for a bulky magnet to be accommodated in the design.

Small and strong Neodymium magnets are also fantastic for a surprising array of home applications. Ideal for situations that have limited space such as the clearance of a door jam or the back of a drawer cavity. Customers can use these to help control a wayward door or an independent minded drawer. Tiny circular magnets are popular for craft purposes as they can be disguised into most designs without causing disruption to the aesthetic appearance.

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.
