Magnetic Product Description:

This rare earth ring magnet has an outside diameter of 20mm, an inside diameter of 10mm and a thickness or height of 8mm. It has a pull force of 7.30 kg. It is identified by the AMF magnet part number 23013.

Uses for our rare earth ring magnets:

All coatings impact the strength and holding ability of a magnet and Epoxy Coatings are no different. In some way compensating for the gap between surfaces that the coating creates, is the N45H Grade material of this ring, which is both high in magnetic energy and can also withstand operating temperatures up to 120° Celcius without failure or demagnetisation. As you would expect, the epoxy protects the Neodymium Ring from abrasive forces and protects it against moisture corrosion. These quality and performance-enhancing characteristics are reflected in the high unit price it attracts.

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.
