The right procedure for every metal

The treatment (pickling, passivating) of various types of metals (alloys) is our core business. Each metal requires its own, specific and specialized metal surface treatment. Thanks to our 70 years of experience with metals, Vecom knows exactly what is needed to ensure that the machined, affected or contaminated metal will be in optimum condition again.

In addition, Vecom can help you to quickly determine which alloys you are dealing with with our metal analyzer. The alloy partly determines the choice of the correct cleaning method. You can read more about the metal analyzer in our Technical Bulletin.

Ferrous and non-ferrous metal

Metals can be subdivided into ferrous metals and non-ferrous metals. Iron products and alloys with iron are called ferrous metals. Non-ferrous metals are all other metals in their pure form, binary, tertiary and more complex metal alloys without iron.

Ferrous metals: steel, cast iron, stainless steel
Non-ferrous metals: aluminium, copper, lead, zinc, bronze, brass

Further highlighted

Below we highlight a number of metal types. We explain what it is and what metal surface treatments are applicable for each metal type.


Stainless steel

Stainless steel is mainly used because of its specific corrosion resistant properties. This corrosion resistance is the result of the natural ability of stainless steel to form a protective oxide skin.

Duplex stainless steel

Duplex stainless steel finds its application mainly because of its high corrosion resistance and mechanical properties. Because of this high resistance to many types of corrosion, in particular stress corrosion, Duplex is preferred over austenitic stainless steel.

Aluminium is one of the most common elements on earth. It is almost twice as prevalent as iron. Because of its many advantageous properties, such as low specific gravity and good corrosion resistance it has an extensive range of applications.

Carbon steel

Carbon steel, also known as construction steel, is the collective name for a group of low-alloyed steels with a high carbon content compared to stainless steel. Rust, mill scale and annealing skin cause contamination of the product, reduce heat transfer and can cause damage.
