Generally speaking, the weight loss is over 150mg/cm2 in the NdFeB industry, but our NdFeB magnets can reach less than 1mg/cm2, (Testing condition: HAST 168 hrs), due to the very low weight loss, the corrosion resistance is excellent, the reliability and working life of low weight loss NdFeB magnets have been improved obviously, and they can meet the strict requirement of corrosion resistance in the application of permanent motors and other fields. Low weight loss NdFeB magnets mainly used in elevator, radar, wind generators, military aerospace, industrial motors and other fields.

High temperature stability NdFeB magnet (Low temperature coefficient NdFeB magnet)
NdFeB magnets are very sensitive to temperature, and their magnetic properties gradually decrease with the gradual increase of temperature, showing a certain linear relationship.
High temperature stability NdFeB magnets are mainly used in car motors, EPS, industrial motors, wind turbine, Elevator etc, it is suitable for all industrial product which operating in high temperature.
Note:  αBr and βHcj are related to the length-diameter ratio and square degree of the product, and the higher the length-diameter ratio and square degree, the higher the maximum operating temperature. We suggest that the length-diameter ratio > 0.5 is the best. Please consult our professional engineers for details.
