Magnetic Product Description:

This neodymium magnetic disc has a diameter of 7mm and a height of 1mm. It has a magnetic flux reading of 1991 Gauss and a pull force of 0.426 kilos. It is identified by the AMF magnet part number D-D7H1-N50.

Uses for our Neodymium disc magnets:

Neodymium magnets have superior magnetic strength compared to other types of permanent magnetic material. This super strong magnetic material has influenced many commercial designs since its adoption in the industrial world during the 1980s. Consumer products that utilise this heavy-duty Rare Earth material are typically smaller in size, while also more powerful with higher capabilities than their predecessors. Neodymium Disc magnets offer low height dimensions and relatively large magnetic pole surface areas. This makes the disc ideal for concealment inside thin electronic devices and hi-tech communications equipment where they can turn on or off electrical circuitry. AMF supplies disc shaped magnets that are manufactured using magnetic grades from N35 to N52. The higher the grade the stronger the Neodymium material and Gauss reading. Neodymium magnets also offer reductions in weight and are utilised throughout industries where weight to power ratios are extremely important. These industries can include Aviation, Aerospace, Robotics and the Military. The size and weight reductions as well as reliability, often compensate for the additional cost associated with Neodymium magnetic products.

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.
