Xinfeng magnet found in the laboratory, the rare earth magnet alloy magnetic can often affected by many factors, over the years has been test, research and development to a new technology to improve the NdFeb permanent magnet coercive force and the Curie temperature, so that to enhance the stability of strong NdFeb rare earth magnetic under Normal Temperature or High Temperature, this performance upgrades to the strong NdFeb magnet industry has very big significance. There are two ways to study the improvement of the coercivity of rare earth permanent magnet alloy: one is to find out the relationship between the coercivity and the physical or geometric parameters of the alloy phase according to a certain physical model and through appropriate mathematical treatment. The other can directly observe the relationship between the microstructure of the alloy or the phase parameters and coercivity through experiments.
Xinfeng magnet company found that cobalt, aluminum with the use of neodymium iron boron alloy, add 10% cobalt, alloy coercivity peak at 4% aluminum; When add 16% cobalt, the peak coercivity of the alloy is at 2% aluminum. The addition of aluminum increases the coercivity of the alloy and cobalt increases the Curie temperature of the alloy. The combination of the two, both improve the neodymium iron boron coercivity, and can improve the Curie temperature of Neodymium iron boron. Xinfeng also found that if add the suitable amount of niobium, the Neodymium iron boron permanent magnet alloy can improve the Curie temperature at the same time, the coercivity will be greatly improved. Inspired by the experimental results, Xinfeng will continue to study the magnetic stability of rare earth permanent magnet alloy, and hope to apply it to the innovation of manufacturing process, the development of alloy components and production as soon as possible, to further improve the quality of products and enhance the core competitiveness of Xinfeng products.
