At present, the global production of magnetic material magnets for magnetizers is mainly concentrated in Asia, Japan mainly uses high-end magnets; my country uses medium and low-end magnets as the main body, and divides parts of high-end product markets; other Southeast Asian countries divides parts of medium and low-end product markets.


Because my country has a good market and investment environment for complete machine equipment, it has accelerated the transfer of ferrite magnet manufacturing in Japan, Europe and the United States to my country. It is estimated that by 2010, my country's output of ferrite magnets will account for more than 60% of global output, and NdFeB magnets will account for 80% of global output. my country now has 1,096 companies producing magnetic materials, including 359 companies producing ferrite, 226 companies producing rare earth magnets and metal magnets, and the rest are manufacturers of supporting equipment and auxiliary materials. There are 197 permanent ferrite production companies with an output of 410,000 tons (360,000 tons of sintered magnets, 50,000 tons of bonded magnets), and 162 companies producing soft ferrites with an output of 300,000 tons (260,000 tons of manganese zinc, 40,000 tons of nickel-zinc and magnesium-zinc), 40,000 tons of neodymium iron boron magnets, and 3,500 tons of aluminum nickel cobalt metal magnets.


my country's ferrite industry basically maintains a growth rate of more than 20%, doubling the output every five years on average. In recent years, the output, quality and grade of ferrite magnets in my country have been greatly improved. Now permanent ferrite products account for 42% of applications in high-tech fields, such as home appliances (microwave ovens, air conditioners, small household appliances), office supplies (copiers, fax machines), cars, motorcycles, high-fidelity audio, and surface sensor components. The application of traditional medium and low-end products accounted for 58%, such as speakers, adsorption magnets, toy motors, and magnetic separation devices. On the whole, the functions of my country's ferrite magnets are mostly in the middle and low grades. Although the output ranks first in the world, the output is not ambition. At present, my country’s total output of magnetic materials is 26.5 billion yuan, permanent ferrite output is 6.2 billion, soft ferrite output is 9.3 billion, and the remaining samarium cobalt magnets, neodymium iron boron magnets and metal magnets account for 11 billion yuan in the market.


With the development of consumer products towards digitalization and high functionality, higher requirements are put forward for magnetic material products, such as high-definition and digitalization of color TVs, and the power loss, magnetic permeability, and operating frequency of soft ferrite are more demanding than analogue machines. high. Other digital video cameras, audio equipment, and inverter air conditioners also put forward higher requirements for advanced magnetic materials. In addition, the development of the car, communications, and computer industries has also led to the development of advanced and sub-magnetic materials.
