SmCo permanent magnet, as the second generation of rare earth permanent magnet, is mainly composed of metallic samarium (Sm), metallic cobalt (Co) and metallic iron (Fe). According to the structure type, it can be divided into 1:5 and 2:17.
FeCrCo permanent magnet is a new type of permanent magnet material in the early 1970s. Its magnetic properties are similar to that of AlNiCo permanent magnet. It can be magnetized by planar octapole and planar multipole, and it can be machined. It is especially suitable for making small and thin permanent magnet components wi...
AlNiCo is one of the earliest permanent magnet materials developed. It is an alloy composed of aluminum, nickel, cobalt, iron and other trace metal elements. Al - ni - co permanent magnet material was developed successfully in the 1930s. At that time, its magnetic properties are the best, and the temperature coefficient is sm...

Maglev transportation is a kind of transportation mode which makes the maglev train float up and run by the magnetic force. It can be divided into electromagnetic levitation and electric levitation in terms of the suspension mechanism. The former is the German TR train adopted by the maglev Shanghai demonstration line, the Ja...
Rare earth permanent magnet material has become an important material in electronic technology communication, used in satellites, radar, traveling wave tubes, circulators, and micro motors, micro recorders, aviation instruments, electronic watches, seismograms and other electronic instruments.The application of rare earth per...
The distribution and concentration of rare earth resources in the world is high. According to the data released by the United States Geological Survey (USGS), the world's total reserves of rare earth resources are about 120 million tons, among which China's reserves are 44 million tons, accounting for about 37.8%, Vietnam's r...
Rare earth permanent magnet motor is one of the three important components of new energy vehicles, which are different from traditional vehicles. It is also the power source of new energy vehicles. There are two kinds of permanent magnet synchronous motor and AC asynchronous motor. Motor is a kind of electromagnetic device wh...
NdFeB, a rare earth permanent magnet material, can produce a strong static magnetic field: the effect of static magnetic field on the human body, there is no clear conclusion in the scientific community. At present a lot of data propagandize magnetic field is beneficial to human body, there are a lot of magnetic therapy instr...
