Neodymium Cylinder - 12 mm x 20 mm | N42
Product code: 21019
Neodymium Cylinder - 12 mm x 20 mm | N42
Product Description:
This neodymium cylinder magnet measures 12 mm (D) x 20 mm (H). It has a magnetic flux reading of 6034 Gauss and a pull force of 5.8 kilos against 3 mm mild steel. GRADE N42.
About cylinder magnets:
Neodymium cylinder magnets are ideal for applications such as acrylic signage, picture frames, joinery. With superior size to strength ratio, magnetic cylinders are suitable for a wide range of applications. AMF Magnets neodymium cylinders come in a variety of sizes and grades. They are handy, all-purpose magnets commonly used in the art displays, mining, engineering, construction, lighting, teaching facilities and for many other commercial and industrial purposes.
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.
