Features and Applications of Bonded Rare Earth Magnets

Abstract

　High-performance rare earth bonded magnets, along with sintered counterpart, have been playing an important role in the technological innovations for ICT (Information and Communication Technologies), FA (Factory Automation), automotive, and green technology areas. Three types of bonded magnet materials; Sm-Co, Nd-Fe-B, and Sm-Fe-N, were commercialized, and their worldwide production has now reached about 10,000 ton/year. In this paper, features and application examples of the rare earth bonded magnets are described.
