Magnetic Product Description:
This rare earth ring magnet has an outside diameter of 18mm, an inside diameter of 10mm and a thickness of 4mm. It is identified by the AMF magnet part number 23008A.
Uses for our rare earth ring magnets:
All Neodymium magnets have more magnetic intensity than other magnetic materials. Ring-shaped magnets have a reduction in volume because of the void, but their ability to fit over shafts or moldings for positioning, make them easy to incorporate into many of today's electronic product designs where light weight and high performance is a mandatory requirement for new and innovative devices. Rare Earth magnets are found in the world's newest technologies, from scientific research and development to the design and manufacture of electric and hybrid automotive technology. While the importance of Permanent Neodymium- based Ring magnets on the development of new technology designs is not to be underestimated, there are many low-tech, yet equally convenient applications where they also assist to make life easier. Simple attachment methods can be applied to Ring magnets because of the void area. String, rope, nails and cable ties can quickly hold a Ring magnet in position for temporary or occasional use. This can be convenient in places where other methods of attachment are impractical or unavailable due to remoteness.
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.
