Neodymium Disc - 20 mm x 3 mm | N42
Product code: 20018
Neodymium Disc - 20 mm x 3 mm | N42
Product Description:
This neodymium disc measures 20 mm (D) x 3 mm (H). It has a magnetic flux reading of 1810 Gauss and a pull force of 4.3 kg.
Product Information:
Magnetism is a well-known technology. Neodymium disc magnets find their way into the design and manufacturing of components across many industries. These rare earth magnets are the most powerful magnetic material available. When high performance is required, choose powerful neodymium magnets.
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.
