With High precision of size It can be made of complex shapes and also be bonded with other components.

Smco magnets have very high magnetic properties and temperature properties. Their Curie temperature can be as high as 710 to 880°C.Maximum working temperature can be 250ro 350°C. So this kind of magnets have the best magnetic stability. They are very good magnetic material for motors and other application with very strict working environment requirement.
