Feature

Sintered Sm-Co Permanent Magnetic Alloys are a group of rare-earth permanent magnetic materials manufactured by Powder metallurgy. They take on a good temperature stability, high coercive force and high energy produc.

Application

Red Sm-Co Permanent Magnetic Alloys are typically used for manufacturing timekeepers, mini high efficiency instruments, magnetic apparatus, and traveling wave tubes, etc.
