China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Neodymium magnets is a very strong magnetic material, which is the first choice of many customers. Some netizens want to know the main composition and percentage of neodymium iron boron magnets. Now, the chinese neodymium magnet manufacturer courage magnet xiaofu will introduce it to you.
The main components of neodymium magnet are metallic neodymium, pure iron and ferroboron alloy. In order to improve the Coercivity, dysprosium will be added, and sometimes others, such as aluminum, cobalt, praseodymium, terbium, will also be added. Its chemical formula is Nd2Fe14B. The following is the proportion of some constituent elements in neodymium magnet:
Neodymium strong magnet main element composition proportion;
Neodymium (Nd): Approximately 25% to 30% of the total mass of ferromagnets.
Iron (Fe): accounts for approximately 63% to 68% of the total mass of ferromagnets.
Boron (B): Approximately 1% to 2% of the total mass of ferromagnets.
Aluminium (Al) : about 0.3 to 0.5%.
Dysprosium (Dy) : about 0.6 to 1.2%.
The following table provides concrete information on the composition of neodymium magnets, It's going to be different at different grades.;
Weight of these elements directly affects the magnetic properties of neodymium iron boron permanent magnets.
Nowadays, many magnetic material manufacturers provide magnet manufacturers with neodymium iron boron magnet blank materials. Due to their different production capabilities and processing methods, the proportion of ingredients is still slightly different.
