Neodymium Disc Magnet - 200mm x 20mm
Magnetic Product Description:
This strong rare earth disc has a diameter of 200mm and a height of 20mm. It is identified by the AMF Magnets part number 19990.
Uses for our strong rare earth disc magnets:
This is our largest diameter Disc and must be HANDLED WITH EXTREME CAUTION to avoid serious injury. Our Neodymium magnets are commonly used for metal separation, picking up nails & screws, water purification, filtration and conditioning, generators, magnetic stirrers and metal detectors. These powerful magnets are also widely used for swarf removal and metal decontamination on construction and demolition sites, and for site remediation and fabrication site cleaning.

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.
