Iron boron, also known as NdFeB magnet, is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). Neodymium magnets were discovered by Masato Sagawa of Sumitomo Metal in Japan in 1982. The magnetic energy product (BHmax) of this magnet is greater than that of samarium cobalt magnets, and it was the material with the highest magnetic energy product in the world at that time.
Strong NdFeB magnets are like electricity, invisible and intangible. Only when iron is close can you feel the magnetic force. Magnets are easy to make and are quite common. Everyone knows that there is a gravitational field between substances. Similar to the magnetic field, it is a field that fills the space around the magnet. The size of the magnetic field can be expressed by the number of imaginary magnetic lines of force. The denser the magnetic lines of force, the stronger the magnetic field. On the contrary, the sparser the magnetic lines of force, the weaker the magnetic field.

In the past two years, the price of high-temperature resistant samarium cobalt magnets has been rising and rising again. Why do the prices of high-temperature resistant samarium cobalt magnets and many other magnets continue to rise instead of falling? In fact, this is mainly because our high-temperature resistant samarium cobalt magnets and other magnets require various rare earth elements in rare earths. These elements are indispensable in our conventional magnet production process, so the price of high-temperature resistant samarium cobalt magnets rises with the price of rare earths. The main reasons for the rise in rare earth prices are the following two points:

Magnetic materials mainly include permanent magnetic materials, soft magnetic materials, signal magnetic materials, special magnetic materials, etc., covering many technical fields. In the fields of rare earth permanent magnetic material technology, permanent magnetic ferrite technology, amorphous soft magnetic material technology, soft magnetic ferrite technology, microwave ferrite device technology, special equipment technology for magnetic materials, etc., a huge industrial group has been formed. Among them, the annual market sales of permanent magnetic materials alone have exceeded 10 billion US dollars.

After two years of effective control, the price of rare earths has stabilized. The rational development and utilization of rare earth minerals has been effectively controlled, and the production of raw materials for rare earth magnets has gradually stabilized. For the entire market, the price of raw materials is stable, so the price of NdFeB strong magnets is relatively stable. Now it is the Internet era, and the price of products is very transparent. When everyone's product quality is the same, the unit price of the product is naturally transparent. If you put a product online for quotation, the price advantage is very obvious. Therefore, product competition depends on products and product competition depends on quality.

NdFeB strong magnet is a common magnet material. With the global mass production of NdFeB strong magnet in recent years, the global production pattern has also changed significantly. The United States, once a strong production country, stopped production at the end of 2003, Europe also basically stopped production, and Japan's growth has greatly reduced. So what exactly caused this situation? What is the industry development status of NdFeB strong magnet? Let us introduce it to you in detail:
