Micro Neodymium Magnets

Definition of micro neodymium magnets

Micro neodymium magnets are also known as tiny neodymium magnets. They are very small, and their dimensions are less than 1mm. Micro neodymium magnets are made from NdFeB blanks. A variety of shapes are available: micro ring magnets, micro disc magnets, micro block magnets and micro cylinder magnets, etc.

Grades of micro neodymium magnets

Designers of micro magnets often choose high grade magnets because they need to achieve the highest energy possible with a small magnet volume. In addition, micro magnets are prone to demagnetization against high opposing magnetic field. For this reason, high coercivity (e.g. UH grade) is required in many micro magnet applications.

Coatings of micro neodymium magnets

Generally, it’s difficult to use conventional coating methods on magnets that are under 1mm. Tengye has tiny magnet coating line that is capable of coating nickel, gold and biocompatible coatings such as parylene.

Manufacture of micro neodymium magnets

Conventionally, neodymium magnets are cut and sliced by EDM (Electrical discharge machining) and diamond multi-wire saw. However, to manufacture micro neodymium magnets, laser cutting technology is needed.
