Rated 5.0 out of 5
3 Reviews
Product Code 20063
Pull Force* 1.7 kg
Weight 2 gm
Style Rare Earth Disc magnet
Coating Nickel (NiCuNi)
Direction of Magnetisation Axially magnetised
Dimensions Height:4mm, Diameter:8.5mm

This neodymium disc magnet has a diameter of 8.5mm and a height of 4mm. It is constructed from rare earth, strong magnetic material. This makes it extremely strong for its size. This disc magnet has a magnetic flux reading of 4318 Gauss and a pull force of 1.7kg. It is identified by the AMF magnet part number 20063.


Uses for our Rare Earth Disc Magnets:


Our neodymium rare earth magnets come in many shapes and sizes, but these discs are one of the most popular. This disc magnet is small enough to fit into any tight space yet thick enough to be easily handled. The ratio of diameter to thickness lend this magnet a surprisingly powerful holding capacity for its size.


Many of our customers glue this magnet to the back of cards or signs to create visual diagrams for anything that needs to be displayed clearly in the home, office or warehouse. Magnets can be easily concealed, this makes them a fantastic choice for customers who want a professional and aesthetically sympathetic finish. These magnets are also commonly found in electric motors, technical instruments and communications equipment.

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.
