Neodymium Cylinder Magnet - 3mm x 20mm
Magnetic Product Description:
This rare earth cylinder magnet has a diameter of 3mm and a height of 20mm. It has a 650 gram pull force. Its part number is 21058.
Uses for our rare earth cylinder magnets:
The elongated shape of this Neodymium cylinder magnet coupled with its small diameter produces a highly concentrated magnetic field through each of the end surfaces. This is a specialty magnet produced from N42 SH material lending it resistance to high temperatures and superior magnetic power. Able to withstand temperatures up to 150º Celsius, this magnet is used in industrial and commercial operations involving heat treatment or prolonged heat exposure that would reduce the effect of lower grade Neodymium material.
No FAQ available
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.
