China's rapid development of magnetic materials

After 20 years of construction and development, China's magnetic material industry has formed its own industrial system. The output of magnetic materials in various categories ranks first in the world, establishing the status of the world's largest producer of magnetic materials and magnetic materials industry. In 2007, China’s output of ferrite magnets reached 460,000 tons, ferrite production reached 350,000 tons, rare earth neodymium-iron boron magnets reached 55,000 tons, and aluminum-nickel-cobalt metal magnets reached 0.35 million tons.
China magnetic material has gone through 3 stages
In 1988, there were 160 magnetic material manufacturers in China, with a total output value of 880 million yuan. By 2007, there were more than 1,200 companies with a total output value of 27.57 billion yuan.
China's soft ferrite has grown from 0.7 million tons in 1988 to 350,000 tons in 2007, an increase of nearly 50 times. China's ferrite magnets have increased from 17,000 tons in 1988 to 460,000 tons in 2007. About 40 times; China's rare earth NdFeB magnets from 9 tons in 1988, developed to 55,000 tons in 2007, an increase of about 6000 times.
China has now become the world's magnetic material center. In 1990, China's aluminum-nickel-cobalt magnets accounted for the first place in the world. In 1995, China's permanent magnet ferrite accounted for the first place in the world. In 2000, China's NdFeB magnets accounted for the world's first. After entering the 21st century, the output of various kinds of magnets in China has already ranked first in the world.
China's magnetic material industry has gone through three stages: First, during the extensive development of the 1980s, the rapid development of China's magnetic material industry, township enterprises have mushroomed. Since the 1980s, China began to form a magnetic material industry system. Due to the needs of the development of the situation and the requirements of enterprises, the China Magnetic Materials Industry Association was established in the mid-1980s. Second, during the period of steady improvement in the 1990s, China’s magnetic material industry has not only developed in terms of quantity, but also noted the improvement in quality and the formation of distinctive backbone enterprises within the industry. Third, the 21st century has entered a period of international development, and joining the WTO has intensified the process of marketization and faces new challenges and opportunities. Chinese ethnic enterprises have expanded outwards to take over foreign bankruptcies and join international large companies. At the same time, foreign companies have also continued to expand into China, which can be said to be in a period of coexistence and competition.
Doing a good job of making fine magnetic materials based on the international market
After joining the WTO, foreign companies entered China to seek low-cost labor, and occupied its high-end application market with its technological superiority, resulting in the development of China's magnetic material industry at a disadvantage. The association timely proposed that enterprises must be bigger, better, and better in order to survive and develop in market competition. In order to be big, the company must have a certain economic scale, become the top of the industry, must have economic strength; do a good job, product quality must keep up with the world's level, product structure is not out of date; do fine, must have its own characteristics Products, in a certain area (price, quality and market share) leading the industry, so that other companies can not compete and replace. With the above three points, companies can stand the test of marketization and can stand undefeated in market competition.
At present, China's soft ferrite applications: high-tech products account for 22% of applications, such as digital communications, electromagnetic compatibility (EMC), radio frequency broadband, anti-electromagnetic interference (EMI), high-definition display and automotive electronics. The application of traditional middle and low-end products accounted for 78%, such as televisions, power adapters, electronic ballasts, ordinary switching power supply transformers and antenna rods.
Application of NdFeB magnets in China: 37% of applications in high-tech products, such as magnetic resonance imaging (MRI), mobile phone vibration, hard disk drive voice coil (VCM), optical disk (DVD, CD-ROM) drive spindles, Electric tools and electric cars. The application of traditional middle and low-end products accounted for 63%, such as audio devices, magnetic adsorption devices, magnetic separators and magnetizers.
China's magnetic material industry will continue to develop rapidly
With the development of industry and changes in consumer electronics, magnetic materials will have a longer development period of 10 years to 20 years. However, the structure of products will undergo major changes and begin to become digital, flat, and integrated. Energy-saving development. Nowadays, China has become one of the largest magnetic material production bases and sales markets in the world and has a good development prospect. It is predicted that in the next 20 years, China's magnetic material industry will also develop at a speed of 10%-20%. The above conclusions are mainly drawn from the following market applications:
Changes in China's home appliance market. Flat-panel TVs, air-conditioning conversion, energy-saving refrigerator compressors and washing machines, electrified kitchen supplies, promote the use of magnetic grades have also changed.
Industrial class machine application development. The automobile industry has become the fifth pillar industry of China's economy. It ranked third in the world in 2007, producing 8 million vehicles in total, and it will reach 10 million in 2010. This is one of the biggest benefits to magnetic materials. The average motor used is 30. With more than 5 speakers, the development of electric vehicles brings a bright prospect to NdFeB magnets.
The IT industry has driven the development of related supporting components, in particular, 300 million hard disk drives (HDDs) worldwide. One-inch hard disk drives have been used in digital video cameras, and digital television hard disk drives have replaced video tape recorders. In 2010, there will be more than 500 million hard disk drives, DVDs, DVD-ROMs, and more than one billion devices worldwide. Laptops are becoming smaller, thinner, and lighter, but their performance is comparable to that of previous supercomputers. This is a huge market for soft-magnetic and NdFeB magnets.
In the communications industry, mobile phones continue to incorporate a variety of functions. Not only do they have the ability to receive and send mobile images and navigation, but they must also have camera functions. These have imposed higher requirements on ferrites.
The requirements for energy conservation and emission reduction have enabled magnetic materials to develop in new areas. The State plans to replace incandescent lamps with electronic energy-saving lamps in 2008. This has brought about positive effects on the development of soft ferrite; wind power generation and renewable energy are new energy sources for the world's development, and China will increase investment in wind power generation in the future. This brings new opportunities for the development of NdFeB magnets.
