What are the components of magnets (elements), in this article will be a detailed introduction to the composition of magnets and its characteristics and some types of magnets.
We know that magnets are made of iron, cobalt, nickel and other atoms, and the internal atomic structure of these components has its own magnetic moment, so it is special. The main elements of NdFeb this kind of strong magnet are divided into rare earth (Re), boron (B), iron (Fe); In order to obtain different properties, rare earth can also be partially replaced by dysprosium (Dy), prasoddymium (Pr) and other rare earth metals, iron can also be replaced by cobalt (Co), aluminum (Al) and other parts of other metals, the boron content of NdFeb strong magnet is small, but it plays a very important role in the formation of tetragonal crystal structure intermetallic compounds, compounds with high saturation magnetization Degree, high uniaxial anisotropy and high distance temperature.
The ternary permanent magnet material of NdFeb is based on Nd2Fe14B compound, whose composition should be similar to the molecular formula of Nd2Fe14B compound. If the Nd2Fe14B composition ratio is completely, the magnetic properties of the magnet will be very low, or even no magnetic. Only when the content of neodymium and boron in the actual magnet is more than that of Nd2Fe14B compound can better permanent magnet performance be obtained.
