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 magnetic material technology, permanent magnetic ferrite technology, amorphous soft magnetic material technology, soft magnetic ferrite technology, microwave ferrite device technology, magnetic material special equipment technology, etc., a huge industrial group has been formed. Among them, the annual market sales of permanent magnet materials alone have exceeded $10 billion.

What products can magnetic materials be used for?

First of all, in the communications industry, billions of mobile phones require a large number of ferrite microwave devices, ferrite soft magnetic devices and permanent magnetic components. Tens of millions of program-controlled switches also require a large number of magnetic cores and other components. In addition, the number of foreign cordless telephone installations has accounted for more than half of the total fixed telephone. This type of telephone requires a large number of magnetically soft ferrite elements. Moreover, videophones are rapidly spreading. It also requires a large number of magnetic elements.

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 components such as neodymium iron boron, ferrite soft magnetic, and permanent magnetic materials.

Third, in the automotive industry, the annual output of automobiles is about 55 million. Based on 41 ferrite permanent magnet motors per car, the automotive industry needs about 2.255 billion motors per year. In addition, the demand for car speakers is also in the hundreds of millions. In short, 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, and electric kitchen appliances, there is also a large demand for magnetic materials. For example, in the lighting industry, the output of LED lamps is very large, and it needs to consume a lot of ferrite soft magnetic materials. In short, tens of billions of electronic and electrical products need to use magnetic materials every year. In many fields, even core magnetic devices with high technical content are needed. 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 materials industry. With the rapid rise of China's electronics and electrical industry, China has become a producer and consumer of magnetic materials. In the near future, more than half of the magnetic materials will be used in the supply 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 China's national economy.
