Research development of bonded permanent magnet materials in China

Bonded permanent magnet materials are widely applied due to its easy preparation, one -step molding into various complex shape. By consulting large volumes of materials, attending conferences and combining self search, this paper analyzes the research development of bonded permanent magnet materials in China in detail, involving raw material, parameters of preparation process, composite bonded magnet, anti -oxidation, anti -corrosion and heat resistance of the bonded magnet. Moreover, this paper also brings forth the target of future research: exploring new fields of application, changing composition and technology, employing new equipment to enhance the magnetic property, carrying out more engineering application research to strength its generalization and industrialization.
