These rare earth alloys are absolutely the ones with the highest specific energy now available. On the same performances, they allow significant size and weight reductions, never reached until now.

Coercive field that degrades significantly when temperature raises.

To avoid irreversible losses, make sure that the operating point is above the knee joint at the maximum operating temperature.

These alloys are very sensitive to corrosion and oxidizing; a protective coating is therefore always suggested.
