English to French Tech/Engineering Engineering: Industrial Magnetic Materials Ferrite

Hard ferrite magnets are made by pre-sintering the required chemical components and then fine milling the resulting ceramic.

This powder is then wet or dry pressed and again sintered before being ground to size.
Ferrite stands out in the magnet industry for three key reasons:

1. It’s the least expensive of the commercial magnetic materials (Samarium Cobalt, Alnico, and Neo)
2. It has the lowest physical properties of all the magnetic materials
3. It has high energy product to cost ratios
