Standard Tolerance of Neodymium Magnets

NdFeB magnet is a commonly used strong magnetic material, its standard tolerance depends on its size, shape and the required accuracy level, the following is the standard tolerance range of sintered NdFeB magnets in general is introduced, I hope it will help you.


In terms of dimensional tolerance, the dimensional tolerance of processed NdFeB magnets is usually within the range of ±0.03-±0.15, depending on the size of the magnets and the precision grade, and magnets of larger sizes usually have a larger tolerance range.


The following chart shows the national standards for dimensional and form tolerances of sintered NdFeB permanent magnet materials


National Standard for Dimension and Shape Deviation of Sintered NdFeB Permanent Magnetic Materials

Standard Tolerance of Neodymium Magnets


Sourced from the national standard GB/T 13560-2017 for sintered NdFeB permanent magnets.


In addition to standard tolerances, our company can also customize according to customer needs. Customized magnets can be adjusted according to the requirements of a specific application in terms of size, shape, magnetic properties, and surface treatment to ensure that the magnets can meet the specific needs of customers.
