Neodymium Disc Magnet 9mm x 2mm N48 Black Nickel
Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
This Neodymium disc magnet is coated in black nickel, has a pull force of 1.19kg, Gauss 2884, Grade N48. It is 2mm in height and has a diameter of 9mm, with a direction of magnetization through height.
These disc shaped Neodymium magnets are useful in a surprising range of applications where space is limited but a precise level of magnetized force is required. The low height dimension is perfect for products with slimmer and sleeker profiles, such as electronic and communications designs where precision and control are vital. Neodymium discs have excellent strength-to-size ratios which means the magnets can be incorporated into design and integrated into performance and operation. In fact, the influential or attractive fields of permanent Neodymium magnets play an increasingly important role in a vast range of modern technologies, from mobile phones to modern automobiles, including electric and hybrid vehicles.
Aerospace projects, where fuel loads and energy are largely finite, also rely on the permanence of magnetic power which is often crucial to their success. The N48 Grade magnetic material used in this magnet is among the highest available and increases the field intensity of this magnet to that of a magnet with larger dimensions.

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.
