Suggested English Text for Performance Table
The above table lists the key magnetic and physical properties of our sintered NdFeB (Neodymium-Iron-Boron) magnets.
Br (Remanence) represents the magnetic flux remaining in the magnet after external magnetization. Higher Br means stronger magnetic force for the same volume.
Hc and Hcj (Coercivity / Intrinsic Coercivity) indicate the magnet's resistance to demagnetization, particularly under external magnetic fields or high temperatures. Higher values ensure stable magnetic performance in demanding applications.
BHmax (Maximum Energy Product) measures the energy density of the magnet, reflecting how much magnetic power is packed in a given volume. Magnets with higher BHmax can provide stronger magnetic force in compact designs.
μr (Relative Permeability) indicates the magnet’s response to external magnetic fields. Lower μr contributes to better field concentration and efficiency in devices.
Operating Temperature shows the maximum continuous temperature at which the magnet maintains its magnetic performance. Selecting the correct grade (M/H/SH/UH/EH) ensures reliability in different thermal environments.
Magnetization Direction determines the internal orientation of magnetic domains, affecting installation and magnetic field distribution in your application.
Understanding these parameters helps you choose the right magnet grade and specification for optimal performance in electric motors, sensors, magnetic assemblies, and industrial equipment.
