Magnetic materials mainly include permanent magnets, strong magnets, special-shaped magnets, Nd-Fe-B magnets, etc., covering many high-tech fields. In the fields of rare earth permanent magnet material technology, permanent ferrite technology, amorphous soft magnetic material technology, soft ferrite technology, microwave ferrite device technology, special equipment technology for magnetic materials and so on, a huge industrial cluster has been formed all over the world.
Where can magnets be used? With the development of society, magnets are more and more widely used, from high-tech products to the simplest packaging magnets. At present, neodymium iron boron magnets and ferrite magnets are the most widely used.
Firstly, in the communication industry, billions of mobile phones around the world need a large number of ferrite microwave devices, ferrite soft magnetic devices and permanent magnetic components. Tens of millions of SPC exchanges around the world also need a large number of high-tech magnetic cores and other components.
Secondly, in the IT industry, hard disk drives, CD-ROM drives, DVD-ROM drives, displays, printers, multimedia audio, laptops, etc. also need to use a large number of neodymium iron boron, ferrite soft magnetic, permanent magnet materials and other components.
Subsequently, in the automotive industry, the global annual output of automobiles was about 55 million. According to the calculation of 41 ferrite permanent magnet motors per vehicle, the automotive industry needs about 2.255 billion motors every year.
At present, ferrite magnet is still the most used permanent magnet material, but the output value of NdFeB magnet has greatly exceeded that of ferrite permanent magnet material. The production of NdFeB magnet has developed into a major industry
In short, magnet materials can cover a large number of electronic and electrical products. It is one of the basic and backbone industrial departments of the material industry. In the next few years, the demand for magnet materials will rise at a rapid speed.
