Neodymium Block Magnets
The neodymium block magnet has a length of 5mm, a width of 5mm and a thickness of 2mm. With a high grade of N50, its pull force is 653 grams. It has a light weight of 3 grams and a maximum operating temperature of 80 degrees celsius.
Neodymium rare earth magnets are stronger than other permanent magnets such as Ferrite, Samarium Cobalt or Alnico magnets. These neo blocks are Nickel coated which is a silver surface that makes them look contemporary. The compact rare earth blocks are extremely popular magnets because even though they are small, they are extremely powerful.
Areas of use for these small rare earth magnets are many. They are favoured with many people who create crafts. They are also used with woodworking as they can be incorporated into many designs including ones that may need to stack the magnetic blocks. This activity serves to create a specific pull force.

Surface Treatment
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.
Range and Tolerance
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.
Magnetic Properties
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.
