Magnetic materials mainly include permanent magnetic materials, soft magnetic materials, signal 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 magnet ferrite technology, microwave ferrite device technology, and magnetic material specialized equipment technology, a huge industrial cluster 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?
Firstly, in the communication 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 Stored program control also need a large number of magnetic cores and other components. In addition, the number of Cordless telephone installed abroad has accounted for more than half of the total number of fixed telephones. This type of phone requires a large number of soft magnetic ferrite components. Moreover, videophones are also rapidly becoming popular. It also requires a large number of magnetic components.
Secondly, in the IT industry, hard drives, CD-ROM drives, DVD-ROM drives, monitors, printers, multimedia audio systems, laptops, etc. also require the use of a large amount of neodymium iron boron, ferrite soft magnets, permanent magnet materials and other components.
Thirdly, in the automotive industry, the annual production of automobiles is approximately 55 million units. Based on the use of 41 ferrite permanent magnet motors per car, the automotive industry requires approximately 2.255 billion motors annually. In addition, the demand for car speakers is also in the billions. In short, the automotive industry consumes a large amount of magnetic materials every year.
Fourthly, there is also a high demand for magnetic materials in industries such as lighting equipment, color televisions, electric bicycles, vacuum cleaners, electric toys, and electric kitchen utensils. For example, in the lighting industry, the production of LED lamps is large, and it requires a large amount of ferrite soft magnetic materials to be consumed. In short, billions of electronic and electrical products require the use of magnetic materials every year, and in many fields, even core magnetic devices with extremely high technological content are needed.
In short, magnetic materials can cover a large number of electronic and electrical products, and are one of the foundation 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
