Many people are unfamiliar with neodymium segment magnets, but I believe most people have heard of them for solid magnets. A strong magnet is another name for a neodymium segment magnet. This kind of magnet is prevalent in modern industry and has a super-strong magnetic force. In addition, neodymium segment magnets are usually tiny and can be used in various spaces and working environments.
If it is stored at an appropriate temperature and humidity without a strong external magnetic field, radiation, and other factors affecting magnetic properties, it can be maintained almost forever.The main factors affecting the magnetism of neodymium segment magnet we should know: temperature and oxidation. When the temperature exceeds the magnet's working temperature range, the magnet's magnetism will weaken or even disappear. When the electroplated layer is damaged, the inner part will be oxidized, and the magnetism of the magnet will also be weakened.
We all know that magnets are widely used daily, and the industry has an excellent demand for magnets. However, there are many kinds of magnets on the market. It is not easy to choose the most suitable magnet. When choosing magnets, many people do not pay enough attention to the production process or types of magnets. Therefore, there will be some problems in the actual use of magnets.
For example, some magnets do not have a long service life, while others cannot withstand high temperatures. However, neodymium segment magnets are produced by special processes and materials. It has the characteristics of small volume, lightweight, strong magnetism and long service life.
Neodymium segment magnet is a permanent magnet based on intermetallic compound Nd2Fe14B. The main components of neodymium segment magnet are neodymium (Nd), iron (FE) and boron (B).
Among them, the rare earth element is mainly neodymium (Nd). Still, to obtain different properties, some rare earth metals such as dysprosium (Dy) and praseodymium (PR) can be used to replace neodymium. It can also be partially replaced by other metals, such as cobalt (CO), aluminium (AL), etc. the boron content is negligible. Still, it plays a vital role in forming intermetallic compounds with tetragonal crystal structures. It makes the compounds have high saturation magnetization, high uniaxial anisotropy and high Curie temperature.
Neodymium segment magnet has high coercivity and will not demagnetize or change under natural and general magnetic field conditions. Assuming that under the appropriate setting, even if it is used for a long time, the magnetic properties of the magnet will not be significantly reduced. Therefore, in practical application, we often ignore the influence of time on the magnetic properties of neodymium segment magnets.
Meank Magnetics, located in the home of Neodymium-Iron-Boron magnets -Ningbo City, have been engaging in the production of rare earth neodymium magnets for over 10 years. After so many years' development in the field of rare-earth permanent magnets, we not only produce the highest grade NdFeB power magnets, but also make different kinds of magnets assemblies (such as holding magnets, pot magnets, separate magnets and other kinds of magnetic tools).
