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 magnetic material technology, permanent ferrite technology, amorphous soft magnetic material technology, soft ferrite technology, microwave ferrite device technology, magnetic material special equipment technology, etc., a huge industrial group has been formed globally. 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 around the world require a large number of ferrite microwave devices, ferrite soft magnetic devices, and permanent magnet components. Tens of millions of program-controlled switches worldwide also require a large number of high-tech magnetic cores and other components. In addition, the number of foreign cordless telephone installations has accounted for more than half of the total fixed telephone. This type of telephone requires a large number of soft ferrite components. Moreover, video phones are also rapidly spreading. It also requires a lot of magnetic components.
Second, in the IT industry, hard drives, CD-ROM drives, DVD-ROM drives, monitors, printers, multimedia audio, notebook computers, etc. also need to use a large number of neodymium iron boron, ferrite soft magnetic, permanent magnetic materials and other components.
Third, in the automotive industry, the global annual output of automobiles is about 55 million. According to the calculation of 41 ferrite permanent magnet motors per car, the automotive industry needs about 2.255 billion motors per year. In addition, the global automotive speaker demand is in the hundreds of millions. In short, the automotive industry consumes a lot 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 great. For example, in the lighting industry, the output of LED lamps is very large, it needs to consume 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 in the world. In many fields, even core magnetic devices with extremely 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 material industry. With the rapid rise of China's electronics and electrical industries, 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-tech magnetic materials and components will also be mainly produced and purchased by Chinese companies. Magnetic materials will also become one of the pillar industries in our national economy.
