As an important material widely used in modern technology and industrial fields, the brittleness of neodymium iron boron magnets is an important concern for people. Brittleness causes neodymium iron boron magnets to easily fracture or break under external forces, thereby affecting their practical application effectiveness and lifespan. In order to reduce the brittleness of neodymium iron boron magnets, we can take a series of effective measures, starting from material design, processing technology, and usage methods.
First of all, in the material design stage, the brittleness of NdFeB magnets can be improved by reasonably selecting the added elements and adjusting the grain structure. For example, adding alloying elements such as rare earth elements and transition metals in appropriate amounts can effectively improve the toughness and tensile strength of NdFeB magnets, thus reducing their brittleness. In addition, optimizing the grain boundary structure by controlling the grain size and distribution can also effectively reduce the material's brittleness and improve its tensile properties.

In terms of processing technology, some measures can also be taken to reduce the brittleness of NdFeB magnets during processing. For example, in the cutting, grinding and other processing processes, the processing speed and tool selection can be controlled to avoid excessive stress concentration and reduce the risk of material rupture. At the same time, in the heat treatment process, reasonable control of temperature and time to avoid excessive hard grain boundaries and interactions can also effectively reduce the brittleness of NdFeB magnets.
There are also some measures that can be taken to minimize the brittleness of NdFeB magnets in terms of use. First, avoid violent collision or twisting to maintain the integrity of the magnet. Secondly, when storing and transporting, care should be taken to avoid environments such as moisture, high temperatures or strong magnetic fields, so as not to cause damage to the magnet. Also, during installation and use, care should be taken to avoid overloading to avoid excessive stress, thus reducing the risk of magnet rupture.
In addition to the above, you can also coat the surface of neodymium magnets with a layer of polymer materials, such as epoxy resin （Epoxy Coated Magnets）. How the magnetic strength is not so big requirements can also be used bonding process（Bonded neo magnets）, toughness and mechanical strength significantly improved.
