NdFeB 38EH is a high coercivity, high-temperature-resistant rare earth permanent magnet material. Compared to conventional N38 and N38SH grades, N38EH offers superior temperature resistance, with a maximum operating temperature of around 200°C. Today, we will introduce the primary applications of this grade of NdFeB magnets and their rough price range.
Neodymium Grade 38EH Main Applications - Electric Vehicle Drive Motors
Electric vehicle drive motors are one of the most important application markets for 38EH. During the operation of the permanent magnet synchronous motor in new energy vehicles, the rotor temperature often reaches 150-180 ° C, with a peak value exceeding 200 ° C. Under such high temperature conditions, ordinary grades of neodymium iron boron will undergo irreversible demagnetization, leading to a decrease in motor performance or even failure. The high coercivity and 200 ° C temperature resistance of 38EH perfectly match this requirement, ensuring stable magnetic performance of the motor throughout its entire lifecycle. Especially in extreme working conditions such as fast charging, climbing, and high speed, where the motor temperature surges, the safety redundancy of 38EH material is even more important, and AH grade is currently being used.

Neodymium Iron Boron 38EH Primary Applications II - Industrial Servo Motors and High-Performance Permanent Magnet Motors
Precision CNC machine tools, industrial robots, high-speed electric spindles, and similar equipment demand exceptionally high motor performance: high power density, low torque ripple, rapid response, and long-term stability. These motors typically operate under continuous heavy loads, with rotor temperatures sustained between 120-160°C. Consequently, magnets must exhibit superior temperature resistance, making 38EH an excellent choice.
In addition, aerospace and defense applications often use 38EH or even higher grades. Regardless of the application, there is a common feature that requires high performance and reliability, and is relatively insensitive to cost.
In terms of price, based on the market situation in late January 2026, the overall price of 38EH raw materials is in the mid to high range, about 380-400 yuan/kg.
The above is an introduction to the application and raw material prices of neodymium 38EH grade. If your company needs to use high-temperature resistant sintered neodymium iron boron strong magnets, please contact the website customer service for quotation and sample processing.
