As we all know, the third-generation rare earth NdFeB permanent magnet is the most powerful magnet in contemporary magnets and is widely used. Its main raw materials are: metal neodymium, pure iron and boron-iron alloy. In order to improve the coercivity, an appropriate amount of metal dysprosium can be added. (Sometimes aluminum, cobalt, praseodymium, dysprosium, terbium, gallium, etc. are added) The general expression is: RE2TM14B (RE=Nd, Pr, Dy TM=Fe, Co).
What is the proportion of NdFeB strong magnet raw materials?
1. Rare earth metal neodymium accounts for 29%-32.5%;
2. The metallic element iron accounts for 63.95-68.65%;
3. The non-metallic element boron accounts for 1.1-1.2%;
4. A small amount of dysprosium is added to account for 0.6-1.2%;
5. Niobium accounts for 0.3-0.5%, and aluminum accounts for 0.3-0.5%;
6. Copper accounts for 0.05-0.15% element;
The quality of these raw materials will be directly related to the magnetic properties of NdFeB permanent magnets.
Now there are many magnet manufacturers that also provide you with neodymium strong magnets, but due to their different production capacity and processing methods, the proportion of ingredients is still slightly different, if you want to know more about magnet information or prices, Welcome to contact Courage Magnet Factory.
