First of all, in the communications industry, billions of mobile phones need a large number of ferrite microwave devices, ferrite soft magnetic devices and permanent magnetic components. Tens of millions of SPC exchanges also need a large number of magnetic cores and other components. In addition, the number of cordless phones installed abroad has accounted for more than half of the total number of fixed phones. This type of telephone requires a large number of soft ferrite components. Moreover, video phones are rapidly becoming popular. It also requires a large number of magnetic components.
Second, 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 NdFeB, ferrite soft magnets, permanent magnet materials and other components.
Third, in the automobile industry, the annual output of automobiles is about 55 million. If 41 ferrite permanent magnet motors are used for each vehicle, the automobile industry needs about 2.255 billion motors every year. In addition, the demand for car speakers is also in the hundreds of millions. In short, the automotive industry needs to consume a lot of magnetic materials every year.
Fourth, magnetic materials are also in great demand in lighting equipment, color TV sets, electric bicycles, vacuum cleaners, electric toys, electric kitchen appliances and other industries. 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 technology content are needed.
In a word, 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 China's electronic and electrical industries, China has become a producer and consumer of magnetic materials. In the near future, more than half of the 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 China's national economy.
