Ferrites

Hard and soft ferrites are the most cost-effective variant of permanent magnets and consist of barium ferrite or strontium ferrite and ferrite oxide. Due to the large deposits of these raw materials, they are inexpensive and most commonly used.

Basic data: can be used from -40 to 200°C, insensitive to oxidation

Available as a rubber magnet, plastic-bonded or as sintered magnet

Area of application: holding magnets, signal transmitters, motors, ...

NdFeB

NdFeB magnets are rare earth permanent magnets that impress with their enormous remanence values. However, due to the use of rare earth raw materials, they are more expensive than ferrites and are used for technologically demanding tasks.

Basic data: can be used from -40 to 220°C, sensitive to oxidation

Available as a plastic-bonded magnet or as a sintered magnet

Area of application: electric motor magnets, signal transmitters, ........

SmCo

SmCo magnets are temperature-insensitive magnets with high coercivity, which makes them insensitive to opposing fields.

Due to the use of rare earth raw materials and cobalt, these magnets are also more expensive than ferrites.

Basic data: can be used from -40 to 350°C, insensitive to oxidation

Available as plastic-bonded magnet or sintered magnet

Area of application: Applications with high temperatures or large stray fields

Plastic bonded magnets

Plastic-bonded magnets are based on either strontium ferrite, NdFeB or SmFeN. All materials can be processed either isotropically or anisotropically.

The impressive advantage of this group of materials lies in the free geometric design. In detail, there are serious magnetic, chemical, physical and economically relevant differences.
