Given that magnets are inherently brittle materials, fine machining them is very challenging.
Therefore, traditional miniature magnets are mainly bonded magnetic products.
Nevertheless, with the advancement of machining machines and technology, more hard magnetic materials are being used to process micro-magnets. Such as samarium cobalt, neodymium iron boron, alnico, ferrite and so on. Currently, samarium cobalt and neodymium iron boron micro magnets are selected more.
