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.
Sintered NdFeB is an anisotropic magnet produced by powder sintering. Generally, only blanks can be produced after sintering, and then they can be made into magnets of various shapes after mechanical processing (such as wire cutting, slicing, grinding, etc.). Sintering of sintered NdFeB refers to the process of heating the green body to a temperature below the melting point of the powder matrix phase and keeping it warm for a period of time in order to further improve the performance and usability of the magnet, improve the contact properties between powders, increase strength, and make the magnet have high-performance microstructural characteristics.

As the third generation of rare earth permanent magnet materials, NdFeB strong magnets have high performance and are widely used in energy, transportation, machinery, medical, IT, microwave, home appliances, aerospace technology and other industries. Especially with the development of knowledge economy represented by information technology, magnet manufacturers continue to bring new uses to rare earth permanent magnet NdFeB industry and other functional materials, which brings a broader market prospect for the NdFeB industry.

I believe everyone knows that in our daily life, magnets are a very common thing, and NdFeB strong magnets are a type of magnet that is widely used. As early as thousands of years ago, the working people of our country made the compass, one of the four great inventions, based on the characteristics of magnets. Until today, magnets are still very useful things. From various electronic devices to daily teaching aids and toys, magnets can often be seen. For this reason, we will take you to learn about the common sense of NdFeB strong magnets in detail:

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.
