Product Introduction

high temperature neodymium magnets with grade SH (120-150

Description

Reviews

High Temperture Neodymium Magnets classified by temperature as SH (120-150 ), UH (150-180 ), EH (180-200 ), AH (200-220 ), RH (220-240 ),TH (240-260 ) . The magnetic strength of NdFeB magnets is closely related to the change of ambient temperature. Within the working temperature range, the corresponding magnetic force will be weakened when the temperature rises by 1 . Sepcail grade Neodymium magnets with low reversible temperture coefficient are available , such as aB from -0.09% to -0.11% aHcj from -0.45 to -0.55 instead of common grade with aB from 0.12% to -0.13% aHcj from -0.55 to -0.65% .Special Grade magnets means can work more stable in high temperature.

These High Temperture Neodymium Magnets is best choice for Electric Vehicles motor,
