Magnetic materials mainly include permanent magnet materials, soft magnetic materials, magnetic materials, special magnetic materials, covering a lot of high-tech fields. In rare earth permanent magnet material technology, permanent magnet ferrite technology, amorphous soft magnetic material technology, soft magnetic ferrite technology, microwave ferrite device technology, magnetic material special equipment technology and other fields, has formed a huge industrial group. Among them, the annual market sales of permanent magnet materials alone has exceeded $10 billion.
In what products can magnetic materials be used?
First, 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 programmed switches also require a large number of components such as magnetic cores. In addition, the number of cordless phones installed abroad has accounted for more than half of the total number of fixed lines. This type of telephone requires a large number of soft magnetic ferrite components. And video phones are spreading fast. 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, laptop computers also need to use a large number of Ndfeb, ferrite soft magnetic, permanent magnetic materials and other components.
Third, in the automobile industry, the annual production of cars is about 55 million. If 41 ferrite permanent magnet motors are used per vehicle, the automobile industry needs about 2.255 billion motors per year. In addition, car speakers are in demand by the billions. In short, the automotive industry needs to consume a large amount of magnetic materials every year.
Fourth, in lighting equipment, color TV, electric bicycles, vacuum cleaners, electric toys, electric kitchen utensils and other industries, the demand for magnetic materials is also great. For example, in the lighting industry, the production of LED lamps is large, it needs to consume a lot of ferrite soft magnetic material. In short, every year, tens of billions of electronic and electrical products require the use of magnetic materials, and in many fields, even the need for highly technical core magnetic devices.
In short, magnetic materials can cover a large number of electronic and electrical products, and is one of the basic and backbone industrial sectors of the material industry. With the rapid rise of electronic and electric industry, our country has become the production and consuming country 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, components will also be mainly produced by enterprises, procurement. Magnetic material will also become one of pillar industries in our national economy.
