Neodymium Ring Magnets
Rare earth magnetic material gives Neodymium magnets their superior strength compared to other variants of permanent magnets. Ring shaped Neodymium magnets like this N45 Grade example are popular with Frenergy customers who value versatility and find the endless range of practical holding or attracting capabilities associated with ring shaped magnets is very appealing. Although the circular central hole reduces the overall amount of magnetic material and magnetic power these magnets produce, the hole is ideal for attaching these ring-type magnets to another surface with wire, a nail or a suitable screw. This non-invasive form of attachment allows a magnetic bond to be quickly installed in a temporary way and then removed without damaging the magnet. Choose the Ring Magnet with the dimensions and pull-for that best suit your needs by browsing the website and using our secure online store. Frenergy customer orders over $50 qualify for free shipping Australia wide.

Surface Treatment
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.
Range and Tolerance
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.
Magnetic Properties
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.
