Types of metal pollution

There are three types of metal pollution:

Iron and steel particles (ferrous metals)

Through the ferritic or martensitic structure they have a high relative magnetic permeability, making them strongly magnetic. These particles are powerfully drawn to magnets.
 

Stainless steel contaminants

These are often wear particles from your production line. Stainless steel has a structure that, in principle, is not attracted to magnets. Mechanically processed or deformed stainless steel, such as a wear particle, is, however, magnetic because the structure changes. With the strongest magnets we can now often also filter these weakly magnetic stainless steel particles from your product stream.
 

Non-ferrous metals, such as aluminium and copper

These are not magnetic and are therefore not attracted by a magnet. However, you can often separate these metals magnetically with eddy current separators.
