Production Process Of Neodymium Iron Boron
Due to the characteristics of the metal, neodymium iron boron is particularly prone to oxidation, so there are high requirements for preservation during the production process from raw materials to blank electroplating and spraying, and the residual materials during the production process are difficult to reuse. Generally, neodymium iron boron enterprises have hydrogen production stations and nitrogen production stations. Hydrogen is used for the crushing of castings, while nitrogen is used to protect materials from oxidation.

The Difference Between Bonded Neodymium Iron Boron And Sintered Neodymium Iron Boron
The main differences between bonded neodymium iron boron and sintered neodymium iron boron are production process, physical properties, application areas, as well as cost and price. 12 Production process: Bonded neodymium iron boron is made by mixing rapidly quenched NdFeB magnetic powder and binder, and then by "pressing molding" or "injection molding". This type of magnet contains a binder, and its density is generally 80% of the theoretical density. In contrast, sintered neodymium iron boron adopts powder metallurgy process, which pulverizes the melted alloy and compresses it into a compact in a magnetic field, and then sinter it in inert gas or vacuum to achieve densification.

The Relationship Between Surface Magnetism And Remanence
Magnetic field refers to the magnetic induction intensity at a certain point on the surface of a magnet, measured in Gauss (Gs) or Tesla (T). Residual magnetism refers to the magnetic induction intensity retained within a ferromagnetic material when it is magnetized to saturation by an external magnetic field and then gradually reduced to zero. Its full name is residual magnetic induction intensity (Br), and the unit is also Gauss (Gs) or Tesla (T).

Do Permanent Magnet Motors Need To Be Magnetized? What Are The Types Of Magnetizing Devices?
With the continuous development of industry and the promotion of rare earth permanent magnet materials, the demand for magnetization equipment in the application industry of permanent magnet motors and other permanent magnet materials is gradually increasing; At the same time, new requirements have been put forward for the energy consumption, volume, magnetization effect and other performance aspects of magnetization equipment. Due to the fact that the magnetization process is completed in a very short period of time, the magnetic field variation is a spatial function. When using simple magnetic circuit empirical calculations, many parameters are difficult to accurately determine and require three-dimensional electromagnetic field numerical calculations. With the rapid development of computer hardware and software technology, finite element method has become a key technology for accurately calculating and analyzing the electromagnetic field of magnetization systems.
