In 1983, Japan's Sumitomo Special Metals Co., Ltd. (later became a subsidiary of Hitachi Metals) invented the neodymium iron boron magnet for the first time, and began mass production the followin...
High-end neodymium-iron-boron magnets need a large amount of heavy rare earths: as the temperature rises, the magnetic properties of NdFeB will deteriorate sharply. The current increase in coercivity ...
Everyone knows about rare earth NdFeB magnets. The main reason most customers choose it is its super strong magnetism. However, it is easy to corrode and oxidize but its shortcomings. Therefore, some ...
As the core midstream material in the electronic information industry, magnetic materials have strong functionality, wide applications and broad market prospects. In the context of vigorously developi...
In 1983, the third generation of neodymium-iron-boron magnet came into being. Its magnetic field strength is more than ten times that of ordinary magnets and its service life is more than ten years. I...
Al-Ni-Co permanent magnet is one of the first permanent magnet materials widely used. Its preparation process and technology are relatively mature.1. Level of developmentThe preparation technology and...
The Al-Ni-Co permanent magnet is an alloy of aluminum, nickel, cobalt, iron, and other trace metals. The composition of Al-Ni-Co permanent magnetic metal is different, the magnetic properties are diff...
Magnetic materials are generally divided into hard magnetic materials and soft magnetic materials.Permanent magnetic materials are materials that have a wide hysteresis loop, high coercivity, and high...
