Neodymium magnet, also called NdFeB magnet, is a tetragonal crystal formed by neodymium, iron, and boron (Nd2Fe14B). This kind of Neodymium Disc Magnet factory is the most commonly used rare earth magnet and is widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. N35 and N52 magnets are two common grades of neodymium magnets. But many people don’t know what is the difference between N35 and N52 magnets. So in this article, we try to make a comparison between them.
The two magnets have the same intrinsic coercivity Hcj level, which is higher than 12kOe (in CGS units) or 955kA/m (in SI units). Their maximum magnetic energy product (BH) max is about 35 and 52 MGOe, respectively. This huge difference means that N52 magnets have about 49% more energy than N35 magnets. In other words, the performance of a motor or device using N52 magnets will be much higher than that of a motor or device using N35 magnets, and it will be smaller and lighter.
Although the N52 magnet has a very high (BH)max at room temperature, which is currently the highest level among commercial magnets, its application is limited to a certain extent due to its high cost (about 50% higher than N35 magnets). In fact, among sintered NdFeB magnets, N35 magnets are the most widely used in various applications. Compared with other permanent magnets, such as ceramic/ferrite magnets, which have a maximum BH of about 4MGOe, N35 magnets are nearly 8 to 9 times powerful than them.
In some cases, neodymium-iron-boron magnets with higher (BH) max are really needed, but magnets of N45, N48, and N50 are already strong enough. By structural design and optimization, these lower-grade magnets can replace the N52 magnet, which can meet the target performance at a relatively lower cost.
Conclusion
Now you may have a better understanding of the difference between N35 and N52 magnets.
