Neodymium Cylinder Magnet - 12.7mm x 12.7mm

Rated 4.8 out of 5
4 Reviews
Product Code 21020
Pull Force* 6 kg
Weight 12 gm
Style Neodymium Cylinder magnet
Coating Nickel (NiCuNi)
Direction of Magnetisation Axially magnetised
Dimensions Height:12.7mm, Diameter:12.7mm

Magnetic Product Description:

This neo cylinder magnet has a diameter of 12.7mm and a height of 12.7mm, the imperial equivalent size of half an inch. It has a flux density reading of 5635 Gauss and a pull force of 6 kilos against 3mm mild steel. Its part number is 21020.

Uses for our rare earth cylinder magnets:

This small but powerful Neodymium magnet is of equal dimensions in height and diameter and can also substitute exactly for 1/2 inch Imperial dimension requirements. North and South pole surfaces are located at each flat, end of the magnet. Holes drilled into a material or where round plastic recesses exist are the most common methods of securing these cylinders for bonding materials together magnetically. Any industry can utilise powerful Neodymium magnetic fields in their products or production methods but those involving plastic bonding, audio and communication equipment and metal fabrication or removal are the most common users. Magnets provide instant, repeatable and non-penetrative bonding,  unlike their outdated predecessors, such as nails, screws and staples. They also provide endless opportunities for holding applications, where they can hold many times their own weight, for displaying graphic or advertising material without the need for glues.

Neodymium Cylinder Magnet - 12.7mm x 12.7mm (21020)

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.

Good strong magnets

Ok firstly if you plan on smashing these together they will chip. For fixed applications they are super strong. I used them to locate metal studs behind plasterboard wall and worked perfectly although something plasticized would be better. Will buy again. Thanks!

Fun

On arrival my kids were immediately testing the limits of the magnets and getting them to fly together. A part of the magnet chipped off, but it still works. we have used it for a monopole motor which was very cool! Then my son dunked it in iron filings. That wasn't so fun....
