NdFeB is a kind of hard magnet. Strong magnet manufacturers produce this kind of magnet because its function is much higher than that of ordinary magnets. Of course, its application range is wider than other magnets. So what are its main functions? In actual use, what aspects should we pay attention to?
NdFeB produced by magnet manufacturers is resistant to high temperatures, with a maximum temperature of 180 degrees Celsius. This mainly depends on its own structure. Even the same brand can reach such a high temperature due to the difference in intrinsic coercive force.
Although the magnet manufacturer says that it is resistant to high temperature, it will be demagnetized at a particularly high temperature. Therefore, many magnet manufacturers need to understand this characteristic of it. Its performance is different from that of ferrite magnets. Ferrite magnets are weak, but they can withstand a maximum temperature of 500 degrees Celsius.
Second, low temperature resistance. We said above that NdFeB can withstand high temperature, so will it affect its various functions in low temperature environment? the answer is negative. Even if the temperature is at a low temperature of -60 degrees Celsius, it will not have any effect on it. On the contrary, the low temperature will enhance its paramagnetism and enhance the stability of its electronic arrangement.
Third, high temperature salt water will affect its function. The magnet manufacturer introduced that although the influence of salt water on the magnetic field is very small, because the magnetic permeability of salt water is very low, but high temperature salt water is different. High temperature salt water contains a lot of ions, even if there is not much damage to NdFeB itself, but to a certain extent Will weaken its effective communication interval.
Therefore, the NdFeB produced by powerful magnet manufacturers is produced according to the customer's customization. According to the different magnetic grades, their performance is also differentiated. Pay attention to the required environment of the magnet to select the working temperature of NdFeB.
