What are the factors that affect the material properties of neodymium magnets n35
The demand for neodymium magnets n35 in the market continues to increase, and the production process and magnet performance of neodymium magnets n35 are also constantly developing and improving.
The demand for neodymium magnets n35 in the market continues to increase, and the production process and magnet performance of neodymium magnets n35 are also constantly developing and improving. The raw material composition and production processing of neodymium magnets n35 determine the magnetic properties of the produced neodymium iron boron magnets. After turning into finished magnets, the natural environment of the neodymium magnets will endanger the full use of their innate magnetic properties. , Demagnetization will occur. Let’s take NdFeB magnets as an example. Let’s take a look at the factors that harm the performance of NdFeB magnets.
1. The hazards of the production process to the performance of neodymium magnets n35
In order to obtain high-performance neodymium iron boron magnets as quickly as possible, the important difficulty in the production process of calcined neodymium iron boron magnets is to prevent the precipitation of its elements and the oxidation of aluminum alloy profiles. The big advantage of adding anti-oxidant to the NdFeB magnet production and manufacturing project is to reduce the oxygen content of the final magnet. In addition, the magnetic particle inspection can be ground finer, which is beneficial to increase the magnetic energy product. In addition, due to the reduced oxygen content, It also helps to increase the magnetic energy product. Coupled with lubricant, the sliding friction in the middle of magnetic particle inspection is reduced, the fluidity of magnetic particle inspection is improved, the degree of orientation is improved, and the magnetic loss is increased.
2. The hazards of natural environment to the performance of neodymium magnets n35
Temperature: NdFeB magnets have strict working temperature limits. When the working temperature is higher than the working temperature, the magnet is likely to be demagnetized, and when the Curie temperature is higher, the magnet demagnetization will be irreversible.
Relative humidity of the air: Forged NdFeB magnets are permanent ferrites that are made by powder metallurgy industry processing technology to inhibit forming. The internal structure has voids and is very easy to oxidize. Therefore, the forged NdFeB magnets are all coated with coatings. Corrosion resistant treatment.
3. The harm of raw material composition to the performance of neodymium magnets n35
In short, neodymium iron boron magnets are neodymium iron boron magnets made of rare earth oxide neodymium, pure aluminum and boron using powder metallurgy industrial processing technology. In order to better further improve the magnetic properties of neodymium iron boron magnets, Other elements can be added, but the addition of elements may have a two-way impact on the performance of the magnet. It should be established according to the specific requirements of the application site of the neodymium iron boron magnet for the performance of the magnetic material, and the elements should be added.
