Magnetic materials mainly include permanent magnetic materials, soft magnetic materials, signal magnetic materials, special magnetic materials, etc., covering many technical 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, special equipment technology for magnetic materials, etc., a huge industrial group has been formed. Among them, the annual market sales of permanent magnetic materials alone have exceeded 10 billion US dollars.

What products can magnetic materials be used for?

First, 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 cordless phones installed abroad has accounted for more than half of the total number of fixed-line phones. This type of phone requires a large number of soft magnetic ferrite components. Moreover, videophones are also rapidly popularizing. It also requires a large number of magnetic components.

Second, in the IT industry, hard disk drives, CD-ROM drives, DVD-ROM drives, monitors, printers, multimedia audio, laptops, etc. also need to use a large number of NdFeB, ferrite soft magnetic, permanent magnetic materials and other components.

Third, in the automotive industry, the annual output of automobiles is about 55 million. Based on the calculation that each car uses 41 ferrite permanent magnet motors, the automotive industry needs about 2.255 billion motors each year. In addition, the demand for car speakers is also in the hundreds of millions. In short, the automotive industry consumes 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, the demand for magnetic materials is also very large. For example, in the lighting industry, the output of LED lamps is very large, and it consumes a large amount of ferrite soft magnetic materials. In short, tens of billions of electronic and electrical products need to use magnetic materials every year, and 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 my country's electronic and electrical industries, my country 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 my country's national economy
