National Standard Evolution and Common Preparation Methods of Sintered NdFeB China's rare earth permanent magnets have the strength to reach the top of the world's magnetic materials market. This is not only because my country is rich in rare earth resources and undertakes the huge production volume of global permanent magnets, but also because the [...]
Grain Boundary Diffusion Technology With the wide application of sintered NdFeB materials in modern industry and electronic technology, especially in the fields of new energy vehicles, industrial robots and mobile intelligence, it is required that NdFeB products be developed towards lightness, thinness, miniaturization and high energy. The requirements for energy product, coercive force and thermal [...]
Common Magnetic Circuit Structure The use scenarios of NdFeB permanent magnets are roughly divided into adsorption, repulsion, induction, electromagnetic conversion, etc. In different applications, the requirements for magnetic fields are also different. The space structure of 3C products is extremely limited, and at the same time requires high adsorption strength. The space structure does not [...]
High Abundance Cerium Magnets With the continuous expansion of the application field of sintered NdFeB and the rapid growth of output, the corresponding rare earth resources have also been exploited in large quantities. Various rare earth elements in rare earth ores are symbiotic, but in the preparation process of NdFeB, mainly praseodymium Pr and neodymium [...]
Cutting process of sendust magnetic ring The sendust magnetic ring is a ring-shaped magnetic conductor, which is one of the most widely used magnetic rings. Simply put, the sendust magnetic ring is composed of aluminum-silicon-iron. Internationally, the sendust magnetic ring can be called It is a magnetic powder core. Its magnetic core loss is much [...]
Low frequency of air conditioner is changed to high frequency, magnetic powder core ushers in demand At the beginning of 2020, in addition to the medical market, production in many other industries was sluggish and demand was urgent. Especially in the home appliance industry, due to the objective reasons of the home economy, the demand [...]

Permalloy Foil with Magnetic Noise Suppression effect at low frequencies Contributing to weight and thickness reduction of devices used for electric and autonomous vehicles Daido Steel Co., Ltd. (President: Takeshi Ishiguro) has launched a new product "STARPAS®-50PC2S", permalloy*1 foil this month, which has excellent performance in suppressing EMC noise*2 (mainly magnetic noise) at low frequencies [...]
Using AI to optimize magnet and improve performance of motor magnet Research and development aimed at improving the performance of motor magnets is currently gaining momentum. This is because motors used in electric vehicles (EVs), which are increasingly in demand, are also urgently required to improve performance under the trend of decarbonization on a global [...]
Rare earth permanent magnets are basically used in almost high-tech industries Rare earth permanent magnet (the core product is NdFeB) is the most common rare earth material, which consumes about 57% of the total amount of rare earth, and has high added value. More than 85% of the output value of rare earth materials is [...]
The application of NdFeB rare earth permanent magnet Neodymium iron boron magnets (NdFeB) are one of the strongest rare earth permanent magnet types available, and their (BH)max is much larger than that of samarium cobalt magnets. Neodymium iron boron magnets have excellent properties, so they are often the magnet of choice for many applications across [...]
