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 magnet material technology, soft magnet ferrite technology, microwave ferrite device technology, and special equipment technology for magnetic materials, a huge industry group has been formed worldwide. 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 communication industry, billions of cell phones around the world need a large number of ferrite microwave devices, ferrite soft magnetic devices and permanent magnetic components. Tens of millions of program-controlled switches around the world also need a large number of high-tech magnetic cores and other components. In addition, the number of foreign cordless phones installed has accounted for more than half of the total number of fixed-line telephones. These phones require a large number of soft magnetic ferrite components. Moreover, the video phone is also rapidly popular. It also needs a large number of magnetic components.
Secondly, in IT industry, hard disk drive, CD-ROM drive, DVD-ROM drive, monitor, printer, multimedia audio, notebook computer, etc. also need to use a lot of neodymium iron boron, ferrite soft magnetic, permanent magnetic materials and other components.
Thirdly, in the automobile industry, the annual output of global automobiles is about 55 million units. According to the calculation of 41 ferrite permanent magnet motors for each car, the automotive industry needs about 2.255 billion motors every year. In addition, the global demand for automotive speakers is also hundreds of millions. In short, the automotive industry needs to consume a large amount of magnetic materials every year.
Fourth, in the lighting equipment, color TV, electric bicycle, vacuum cleaner, electric toys, electric kitchen appliances and other industries, magnetic materials are also in great demand. For example, in the lighting industry, the production of LED lamps and lanterns is large, and it needs to consume a large amount of ferrite soft magnetic materials. In short, tens of billions of electronic and electrical products worldwide need magnetic materials every year, 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 is 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 the world's largest producer and consumer of magnetic materials. In the near future, more than half of the world's magnetic materials will be used to supply the Chinese market. Many high technology magnetic materials and components will be mainly produced and purchased by Chinese enterprises. Magnetic materials will also become one of the pillar industries in China's national economy.
