Neodymium Block Magnet - 10mm x 2.3mm x 3.3mm | N50 | Black Epoxy Coating

Neodymium Block magnets with Epoxy coating overcome the corrosion problems associated with traditional Nickel based coatings. This makes them ideal for outdoor use and locations where exposure to corrosive elements occurs, including Marine, Industrial and Agricultural environments. Epoxy also increases mechanical strength to the normally brittle Neodymium material and makes the magnet more durable. However, the added cost and the air gap created by the coating make Epoxy coated magnets slightly less powerful and more expensive. Higher magnetic grades like this N50 item are used to help overcome this reduction in power. For specialised, long term use in exposed environments, Epoxy coated Neodymium magnets can provide long-lasting performance and increased durability in situations where uncoated magnets would degrade and eventually fail.

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.
