[Types of metal pollution]

Types of metal pollution

Most metal pollution is magnetically attractable or repellent

There are three types of metal pollution:

  1. 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.
     
  2. 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.
     
  3. 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.
