The Development Prospect of Magnetic Material Industry

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 magnetic material technology, permanent ferrite technology, amorphous soft magnetic material technology, soft ferrite technology, microwave ferrite device technology, and special equipment technology for magnetic materials, a huge industry group has been formed around the world. Among them, the annual market sales of permanent magnet materials alone have exceeded US$10 billion.


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 magnetic components. Tens of millions of program-controlled switches in the world also require a large number of high-tech magnetic cores and other components. In addition, the number of installed cordless phones has accounted for more than half of the total number of fixed phones, which require a large number of soft ferrite components. Moreover, videophones are rapidly spreading, and 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, notebook computers, etc. also require a large number of components such as neodymium iron boron, ferrite soft magnetic, and permanent magnetic materials.


Third, in the automotive industry, the global annual output of automobiles is approximately 55 million. According to the calculation of 41 ferrite permanent magnet motors used in each car, the automobile industry needs about 2.255 billion motors every year. In addition, the global demand for car speakers is also hundreds of millions. In short, the automotive industry needs to consume 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, there is also a great demand for magnetic materials. For example, in the lighting industry, the output of LED lamps is very large, and it needs to consume a lot of ferrite soft magnetic materials. Every year, tens of billions of electronic and electrical products in the world need to use magnetic materials. 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 are one of the basic and backbone industrial sectors of the materials industry. With the rapid rise of the electronics and electrical industries, magnetic materials will become one of the pillar industries in the national economy.
