Main features of NdFeB

NdFeB permanent magnet materials have relatively good magnetic properties and are widely used in electronics, electric machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. The more common ones are permanent magnet motors, speakers, magnetic separators, Computer disk drives, magnetic resonance imaging equipment, etc. The following is a brief introduction for you, hoping to bring you some help. NdFeB, also called NdFeB magnet, is a tetragonal crystal formed by neodymium, iron, and boron. Neodymium magnets were discovered in 1982 by a real person from Sagawa, Japan. The magnetic energy product of this magnet was greater than that of samarium cobalt magnet, and it was the substance with the largest magnetic energy product at that time in the world. Later, Sumitomo Special Metals successfully developed the powder metallurgy method. General Motors has successfully developed a spin-blown smelting process capable of preparing NdFeB magnets. This magnet is the most magnetic permanent magnet today, and the most commonly used rare earth magnet. NdFeB is simply a kind of magnet, which is different from the magnets we usually see.

 Yes, it is called "Magnetic King" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth element neodymium, as well as iron and boron. Its characteristics are hard and brittle. Because the surface is easily corroded by oxidation, NdFeB must be surface-coated. Surface chemical passivation is one of the good solutions. NdFeB is a rare earth permanent magnet material with high magnetic energy product and coercive force. At the same time, the advantages of high energy density have made NdFeB permanent magnet materials widely used in modern industry and electronic technology, making it possible to miniaturize, lighten and thin instruments, electro-acoustic motors, and magnetic separation magnetization. NdFeB has the advantages of high cost performance and good mechanical properties, but its disadvantages are low operating temperature, poor temperature characteristics, easy powdering and corrosion. Must be adjusted by its chemical composition and adoption

 Surface treatment methods to improve its performance to meet the requirements of practical applications. Nd-Fe-B magnetic materials are the latest achievements in the development of rare earth permanent magnet materials, and are known as "the king of magnets" for their excellent magnetic properties. Nd-Fe-B magnetic material is made of rare earth, neodymium metal, ferro-boron and other alloys, also known as magnetic steel.
