Magnetic Product Description:

These Plastic Coated Neodymium Magnets are made from strong magnetic material and have a plastic coating to protect it from corrosion and from potential cracking. They have a countersunk hole in the centre, enabling it to be mounted onto surfaces and to be used for joinery and holding applications. It has an internal diameter of 4.5mm, an outside diameter of 16.5mm and a thickness of 6mm.

Uses for our Rare Earth ring magnets:

The countersunk hole in the centre of this plastic coated neodymium ring allows for the user to mount the magnet on a surface such as a wall or a door. This allows you to join or hold certain items in place. The plastic coating protects the strong magnet from damage. These magnets can also be used for water conditioning, picking up nails and screws, metal detectors and stud finders.

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.
