Magnet Shape
Sintered magnets: A magnet formed user powder and metalworking technologies involving the heating below the melting point of a green product compressed from metal or powder material.
Many permanent materials can be manufactured using a sintering process. The preform materials are mixed and compressed to the required shape under pressure. Magnets with anisotropic properties are compressed in a magnetic field using specially manufactured electromagnetic tools. After being shaped, these so-called "green products" undergo a high-temperature treatment known as sintering. During this treatment, they increase in density and rigidity and the magnets acquire their final form and strength.

The sintered materials are very hard and brittle.
