Friends who have bought neodymium iron boron powerful magnets know that neodymium iron boron magnetic materials have multiple performance grades, because when you inquire with the magnet manufacturer or take samples, you are usually asked what performance grades or grades of neodymium iron boron you need. Magnets used for general packaging handbags and leather goods are usually N series, N35 or lower. The magnets used in the motor usually need to withstand high temperatures of over 100 degrees Celsius, so there are more H and SH materials. Therefore, when purchasing magnets, it is also necessary to pay attention, otherwise it may result in the purchased magnets not working properly and wasting money in vain.

Below is an introduction to the main application fields of sintered neodymium iron boron magnetic materials of various grades. The N series and M series are mainly used in MRI, audio home appliance series products, VCM, magnetic separators, and consumer electronics. The H series is mainly used in the fields of motors and sensors, while the intrinsic coercivity of the SH series is further improved, gradually applied in fields such as wind turbines and industrial motors that require high magnetic material performance, The UH series is mostly used for automotive motors and air conditioning compressors, while the EH series with the best magnetic performance is widely used in fields such as hybrid vehicles, electromagnetic valves, and sensors.
