Development Status of Rare Earth Permanent Magnet Materials and Their Applications

  One of the most important application fields of rare earth permanent magnet NdFeB materials is an important basic material supporting the modern electronic information industry. , as large as automobiles, generators, medical instruments, etc., permanent magnet materials are ubiquitous. It is precisely because of the wide application of rare earth permanent magnet materials that the size of many electronic products has been further reduced and the performance has been greatly improved.   The current situation of the global rare earth permanent magnet industry:   In recent years, due to the high production cost in developed countries and the continuous decline in the price of magnets in the international market, it is unsustainable to continue to produce magnets in these countries. Therefore, the magnetic material enterprises in western developed countries represented by the United States and Europe have carried out industrial adjustment. Great changes have taken place in the international pattern of NdFeB industry. In terms of sintered magnets, Ugimag in the United States was sold to McQueen in 2000. In 2003, McQueen made an industrial adjustment to shut it down and transferred the production of magnetic materials to China. At the beginning of the 21st century, the British Morgan Group acquired the vacuum smelting company (Vacuumschmelze or VAC) of Germany's Siemens and the American Crucible Company, but in June 2003, the Morgan Group closed the American Crucible Company (Crucible). In 2005, the Morgan Group sold the German vacuum smelting company to JPMorgan of the United States. At present, the rare earth industry in the United States has gone from the glory of the past to the decline of today. There are only two sintered NdFeB manufacturers in Europe, one is a vacuum smelting company in Germany and the other is Neorem in Finland. In June 2003, Hitachi Metals purchased the shares of Sumitomo Tekin under Sumitomo Metals, becoming the world's largest NdFeB manufacturer. In terms of bonded magnets, most of the global production capacity is concentrated in Japanese companies.

The history of rare earth permanent magnet materials

  Rare earth permanent magnet materials refer to permanent magnet materials made of alloys formed by rare earth metals and transition metals through a certain process. Now it is divided into the first generation (RECo5), the second generation (RE2TM17) and the third generation of rare earth permanent magnet materials (NdFeB).   As one of the most important application fields of rare earth materials, NdFeB materials are one of the important basic materials supporting the modern electronic information industry and are closely related to people's lives. With the popularization of communication equipment such as computers, mobile phones and car phones and the rapid development of energy-saving vehicles, the world's demand for high-performance rare earth permanent magnet materials has grown rapidly. In 1998, the world's output of NdFeB (including sintered magnets and bonded magnets) reached 11,300 tons, and the annual growth rate in recent years has remained above 30%. The rapid development of rare earth permanent magnet materials is eye-catching.

Which industry category does the production of rare earth permanent magnet materials belong to?

  [Rare earth permanent magnet material] refers to a permanent magnet material made of an alloy formed by rare earth metals and transition metals through a certain process. Rare earth permanent magnet materials have been widely used in the fields of machinery, electronics, instrumentation and medical treatment.   Rare earth permanent magnet material is a kind of magnetic material made of alloys composed of samarium and neodymium mixed rare earth metals and transition metals (such as cobalt, iron, etc.), which are pressed and sintered by powder metallurgy method and magnetized by a magnetic field.   Rare earth permanent magnets are divided into samarium cobalt (SmCo) permanent magnets and neodymium iron boron (NdFeB) permanent magnets. Among them, the magnetic energy product of SmCo magnet is between 15-30MGOe, and the magnetic energy product of NdFeB magnet is between 27-50MGOe. Although samarium cobalt permanent magnets have excellent magnetic properties, they contain rare rare earth metal samarium and cobalt, a scarce and expensive strategic metal cobalt. Therefore, its development has been greatly restricted. The development of my country's rare earth permanent magnet industry began in the late 1960s. At that time, the leading product was samarium-cobalt permanent magnets. The world's sales volume of samarium-cobalt permanent magnets was 630 tons, and 90.5 tons in my country (including SmCo magnetic powder), mainly used in military industry. Technology.

Rare earth permanent magnet properties

  With the development of computer, communication and other industries, the rare earth permanent magnet industry, especially the Nd-FeB permanent magnet industry, has developed rapidly.   Rare earth permanent magnet material is a permanent magnet material with the highest comprehensive performance now known, its magnetic performance is more than 100 times higher than that of the magnetic steel used in the 90th century, and its performance is much better than that of ferrite and aluminum-nickel-cobalt. The magnetic properties of expensive platinum-cobalt alloys are also twice as high.   Due to the use of rare earth permanent magnet materials, it not only promotes the miniaturization of permanent magnet devices, improves the performance of products, but also promotes the production of some special devices. Development is extremely rapid. The performance of various rare earth permanent magnet materials developed and produced in my country has approached or reached the international advanced level.

What is rare earth permanent magnet material?

  Rare earth permanent magnet materials, that is, permanent magnet materials contain rare earth metals as alloying elements. Permanent magnet material refers to the magnetic field that can be maintained for a long time by removing the external magnetic field after magnetization.   Rare earth permanent magnets are divided into: samarium cobalt (SmCo) permanent magnets and neodymium iron boron (NdFeB) permanent magnets. Among them, the magnetic energy product of SmCo magnet is between 15-30MGOe, and the magnetic energy product of NdFeB magnet is between 27-50MGOe. Although samarium cobalt permanent magnets have excellent magnetic properties, they contain rare rare earth metal samarium and cobalt, a scarce and expensive strategic metal cobalt. Therefore, its development has been greatly restricted.   The development of my country's rare earth permanent magnet industry began in the late 1960s.
