General Description:

Neodymium magnets offer the highest energy density than all other permanet magnets.As the strip casting and HD process were used in our factory , we developed high corrosion resistant grade that give superiour weight loss test results,some grade even less than 1.5mg/cm2 in HAST test. Most of such magnets were used in motor ,generator. The size ,shape and coating can be supplied according to customer’s requirement.

Surface Treatment Method:

Due to its low Curie temperature, poor temperature characteristics and easy oxidization to powder, NdFeB magnet must be protected by surface treatment to improve corrosion resistance. According to customers’ requirements, we may provide following platings:

Physical Properties:
