And Our technology is introduced from Japan and Germany. The major technical leader in our factory is from Japan and has been studying this field for over 15 years.Wish Printing Machinery our best technology can solve your production problems.1. Product Details

Samarium Cobalt permanent magnet is widely used second generation high energy material. Using Samarium and Cobalt as its rare earth element, it exhibits high magnetic performance characteristics in energy product and coercive force. There are two compositions of magnets in this family: Sm1Co5 and Sm2Co17. The highest commercially available energy products of Sm2Co 17 are in the 30MGOe range.
