Neodymium Disc Magnet - 6mm x 3mm | N42SH

Magnetic Product Description:

This rare earth disc magnet has a diameter of 6mm and a height of 3mm. It has a magnetic flux reading of 4667 Gauss and a pull force of 890 grams. It is identified by the AMF magnet part number 93003A.


Uses for our rare earth disc magnets:

This small Neodymium disc magnet may look like the other neo discs we have in the same size, however, there is one major difference. The N42SH grade of this magnet allows it to withstand temperatures of 150 degrees Celsius without losing its magnetic integrity and pull force. These unique physical qualities are created during the manufacturing process in the factory. Most Neodymium magnets of a lower grade can only withstand temperatures of 80 degrees Celsius. The benefit of this product is its versatility and can be used in industrial and commercial applications where there is an exposure to higher temperatures.

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.
