N35H and N38H are branches of neodymium magnets, which are commonly used in various industries such as medical imaging equipment (MRI machines), motors, microwave communication, lithography machines, and even SpaceX’s artificial rockets. These magnets also find wide applications in other fields like hard disk drives and magnetic separation technology. You can explore many unknown applications of neodymium magnets on the “TENGYE” platform. In fact, many customers who consulted with “TENGYE” via email specifically mentioned their requirements for N35H and N38H grade neodymium magnets, and made parameter comparisons between these two products.
What does N35H grade neodymium magnet mean?
N35H grade neodymium magnet refers to a magnet with a maximum energy product of 35 MGOe, which can operate normally in environments with a maximum temperature of 248 degrees Fahrenheit. This can be represented by the magnetic hysteresis loop. In Sintered Neodymium (NdFeB) Magnets, you can learn about different grades of neodymium magnets, where higher grades indicate stronger coercivity. In this context, higher coercivity means that the magnet has a stronger resistance to demagnetization as the temperature increases, assuming other external factors remain constant.
During the manufacturing process of neodymium magnets, over a dozen complex processes are employed to produce the desired neodymium iron boron magnets. Different grades of neodymium magnets are formed based on the selection of materials and various manufacturing techniques throughout the production process.
What does N38H mean?
Compared to the N35H grade, N38H has advantages in terms of both coercivity and residual magnetism. However, both of them can withstand a maximum operating temperature of 248 degrees Fahrenheit. Among our existing customer base, N35H and N38H arc motor magnets are commonly used in motors.
Shapes of N35H and N38H Magnets
Below are the product images of neodymium magnets, including their shapes and sizes, provided by “TENGYE” for customers.
Why did 1/3 of “TENGYE” customers choose N35H and N38H neodymium magnets in 2023?
The N35H and N38H arc motor magnets we sell have distinct advantages in terms of coercivity and heat resistance below 248 degrees Fahrenheit. Although their heat resistance is lower than that of N38TH (H38TH neodymium magnet with a maximum energy product of 310 Kj/m3 and a maximum operating temperature of 500 degrees Fahrenheit), N35H and N38H have respective maximum energy products of 287 Kj/m3 and 310 Kj/m3. From an economic perspective, customers find N35H and N38H more affordable. Additionally, higher-grade neodymium magnets correspond to higher prices.
For instance, if your product requires the use of neodymium magnet components, but you are unsure of “what type of neodymium magnet to choose,” you should first calculate the required magnetic energy product to ensure proper product operation. Then, determine the temperature at which your product will operate (the highest temperature generated during operation or the highest temperature it will face). Subsequently, select the appropriate grade of neodymium magnet from the Sintered Neodymium (NdFeB) Magnets section and inquire about the price. We will recommend suitable product grades for your application.
Conclusion
We hope that this article has provided you with a better understanding of N35H and N38H neodymium magnets, making it easier for you to choose the right products for your needs.
