The development prospect of magnetic material industry

Magnetic materials mainly include permanent magnetic materials, soft magnetic materials, letter magnetic materials, special magnetic materials, etc., covering many high-tech fields. In the fields of rare earth permanent magnet material technology, permanent magnet ferrite technology, amorphous soft magnetic material technology, soft ferrite technology, microwave ferrite device technology, and special equipment technology for magnetic materials, a huge industrial group has been formed. Among them, the annual market sales of permanent magnet materials alone have exceeded 10 billion US dollars.

What products can magnetic materials be used for?

First of all, in the communication industry, billions of mobile phones require a large number of ferrite microwave devices, ferrite soft magnetic devices and permanent magnet elements. Tens of millions of program-controlled switches also require a large number of components such as magnetic cores. In addition, the number of foreign cordless telephone installations has accounted for more than half of the total number of fixed telephones. Such phones require a large number of soft ferrite components. Moreover, videophones are 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, monitors, printers, multimedia audio, notebook computers, etc. also need to use a large number of NdFeB, ferrite soft magnetic, permanent magnet materials and other components.

Third, in the automobile industry, the annual output of automobiles is about 55 million. Calculated based on the use of 41 ferrite permanent magnet motors per vehicle, the automotive industry needs about 2.255 billion motors every year. In addition, the demand for car speakers is also in the hundreds of millions. In conclusion, the automotive industry needs to consume a large amount of magnetic materials every year.

Fourth, in industries such as lighting equipment, color TVs, electric bicycles, vacuum cleaners, electric toys, electric kitchen utensils, etc., magnetic materials are also in great demand. For example, in the lighting industry, the output of LED lamps is very large, and it needs to consume a large amount of ferrite soft magnetic materials. In short, every year, tens of billions of electronic and electrical products need to use magnetic materials, and in many fields, even core magnetic devices with extremely high technical content are required.

In short, magnetic materials can cover a large number of electronic and electrical products, and are one of the basic and backbone industrial sectors of the material industry. With the rapid rise of my country’s electronics and electrical industries, my country has become a producer and consumer of magnetic materials. In the near future, more than half of all magnetic materials will be used to supply the market. Many high-tech magnetic materials and components will also be mainly produced and purchased by enterprises. Magnetic materials will also become one of the pillar industries in my country’s national economy
