Neodymium Disc Magnet - 22mm x 12.7mm

Magnetic Product Description:

This rare earth disc has a diameter of 22mm and a height of 12.7mm. It is identified by the AMF magnet part number 20008A and has a pull force of 14.6 kilos.


Uses for our rare earth disc magnets:

Turnkey solution. Rotary motion. From turning water into wine or a frog into a prince, the world turns and so do turnkey solutions in the exacting standards of detailing in the retail joinery industry. No matter how complex, for retail joinery attention to detail is paramount. No excuses.

The phrase turnkey was originally used to describe a person who held the keys to the prison. In retail joinery the phrase has come to mean fitting out a retail space with equipment fit for purpose yet not so specific that it would not satisfy many other buyers in the same industry. Magnets were used in some of the earliest prison locks, to hold or release the various components, to keep prisoners securely inside their cells.

Today these neodymium disc magnets are used in some of the locks to protect retail spaces from those who prefer to visit retail spaces after closing time. Magnetisation plays a significant role throughout the retail joinery production process. When simplicity and discretion, attention to detail and cost are important, many skilled joiners turn to 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.
