Magnetic materials mainly include permanent magnet materials, soft magnetic materials, magnetic materials, special magnetic materials, 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, and magnetic material special equipment technology, a huge industrial cluster has been formed all over the world. Among them, the annual market sales of only permanent magnet materials have exceeded 10 billion US dollars.
What products can magnetic materials be used for?
First, in the communications industry, billions of mobile phones worldwide require a large number of ferrite microwave devices, ferrite soft magnetic devices, and permanent magnet components. Tens of millions of program-controlled switches around the world also require a large number of components such as high-tech magnetic cores. In addition, the number of foreign cordless phones installed has accounted for more than half of the total number of fixed phones. This type of phone requires a large number of soft ferrite components. Moreover, videophones are also rapidly gaining popularity. It also requires a lot of magnetic components.
Second, in the IT industry, hard disk drives, CD-ROM drives, DVD-ROM drives, displays, printers, multimedia audio, notebook computers, etc. also need to use a large number of components such as neodymium iron boron, ferrite soft magnetic, permanent magnet materials.
